github.com/hashicorp/go-getter 1.7.1 (golang) pkg:golang/github.com/hashicorp/[email protected] Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') Affected range >=1.5.9 <1.7.4 Fixed version 1.7.4 CVSS Score 9.8 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H EPSS Score 0.043% EPSS Percentile 11th percentile Description When go-getter is performing a Git operation, go-getter will try to clone the given repository. If a Git reference is not passed along with the Git url, go-getter will then try to check the remote repository’s HEAD reference of its default branch by passing arguments to the Git binary on the host it is executing on. An attacker may format a Git URL in order to inject additional Git arguments to the Git call. Consumers of the go-getter library should evaluate the risk associated with these issues in the context of their go-getter usage and upgrade go-getter to 1.7.4 or later. Improper Neutralization of Special Elements used in a Command ('Command Injection') Affected range <1.7.5 Fixed version 1.7.5 CVSS Score 8.4 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H EPSS Score 0.043% EPSS Percentile 11th percentile Description HashiCorp’s go-getter library can be coerced into executing Git update on an existing maliciously modified Git Configuration, potentially leading to arbitrary code execution. When go-getter is performing a Git operation, go-getter will try to clone the given repository in a specified destination. Cloning initializes a git config to the provided destination and if the repository needs to get updated go-getter will pull the new changes . An attacker may alter the Git config after the cloning step to set an arbitrary Git configuration to achieve code execution.

The documentation for ServerConfig.PublicKeyCallback says that "A call to this function does not guarantee that the key offered is in fact used to authenticate." Specifically, the SSH protocol allows clients to inquire about whether a public key is acceptable before proving control of the corresponding private key. PublicKeyCallback may be called with multiple keys, and the order in which the keys were provided cannot be used to infer which key the client successfully authenticated with, if any. Some applications, which store the key(s) passed to PublicKeyCallback (or derived information) and make security relevant determinations based on it once the connection is established, may make incorrect assumptions. For example, an attacker may send public keys A and B, and then authenticate with A. PublicKeyCallback would be called only twice, first with A and then with B. A vulnerable application may then make authorization decisions based on key B for which the attacker does not actually control the private key. Since this API is widely misused, as a partial mitigation golang.org/x/[email protected] enforces the property that, when successfully authenticating via public key, the last key passed to ServerConfig.PublicKeyCallback will be the key used to authenticate the connection. PublicKeyCallback will now be called multiple times with the same key, if necessary. Note that the client may still not control the last key passed to PublicKeyCallback if the connection is then authenticated with a different method, such as PasswordCallback, KeyboardInteractiveCallback, or NoClientAuth. Users should be using the Extensions field of the Permissions return value from the various authentication callbacks to record data associated with the authentication attempt instead of referencing external state. Once the connection is established the state corresponding to the successful authentication attempt can be retrieved via the ServerConn.Permissions field. Note that some third-party libraries misuse the Permissions type by sharing it across authentication attempts; users of third-party libraries should refer to the relevant projects for guidance. Insufficient Verification of Data Authenticity Affected range <0.17.0 Fixed version 0.17.0 CVSS Score 5.9 CVSS Vector CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N EPSS Score 94.860% EPSS Percentile 99th percentile Description Summary Terrapin is a prefix truncation attack targeting the SSH protocol. More precisely, Terrapin breaks the integrity of SSH's secure channel. By carefully adjusting the sequence numbers during the handshake, an attacker can remove an arbitrary amount of messages sent by the client or server at the beginning of the secure channel without the client or server noticing it. Mitigations To mitigate this protocol vulnerability, OpenSSH suggested a so-called "strict kex" which alters the SSH handshake to ensure a Man-in-the-Middle attacker cannot introduce unauthenticated messages as well as convey sequence number manipulation across handshakes. Warning: To take effect, both the client and server must support this countermeasure. As a stop-gap measure, peers may also (temporarily) disable the affected algorithms and use unaffected alternatives like AES-GCM instead until patches are available. Details The SSH specifications of ChaCha20-Poly1305 ([email protected]) and Encrypt-then-MAC (*[email protected] MACs) are vulnerable against an arbitrary prefix truncation attack (a.k.a. Terrapin attack). This allows for an extension negotiation downgrade by stripping the SSH_MSG_EXT_INFO sent after the first message after SSH_MSG_NEWKEYS, downgrading security, and disabling attack countermeasures in some versions of OpenSSH. When targeting Encrypt-then-MAC, this attack requires the use of a CBC cipher to be practically exploitable due to the internal workings of the cipher mode. Additionally, this novel attack technique can be used to exploit previously unexploitable implementation flaws in a Man-in-the-Middle scenario. The attack works by an attacker injecting an arbitrary number of SSH_MSG_IGNORE messages during the initial key exchange and consequently removing the same number of messages just after the initial key exchange has concluded. This is possible due to missing authentication of the excess SSH_MSG_IGNORE messages and the fact that the implicit sequence numbers used within the SSH protocol are only checked after the initial key exchange. In the case of ChaCha20-Poly1305, the attack is guaranteed to work on every connection as this cipher does not maintain an internal state other than the message's sequence number. In the case of Encrypt-Then-MAC, practical exploitation requires the use of a CBC cipher; while theoretical integrity is broken for all ciphers when using this mode, message processing will fail at the application layer for CTR and stream ciphers. For more details see https://terrapin-attack.com. Impact This attack targets the specification of ChaCha20-Poly1305 ([email protected]) and Encrypt-then-MAC (*[email protected]), which are widely adopted by well-known SSH implementations and can be considered de-facto standard. These algorithms can be practically exploited; however, in the case of Encrypt-Then-MAC, we additionally require the use of a CBC cipher. As a consequence, this attack works against all well-behaving SSH implementations supporting either of those algorithms and can be used to downgrade (but not fully strip) connection security in case SSH extension negotiation (RFC8308) is supported. The attack may also enable attackers to exploit certain implementation flaws in a man-in-the-middle (MitM) scenario.

While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function.

The protocol does not require the client and server to coordinate the cancellation in any way, the client may do it unilaterally. The client may also assume that the cancellation will take effect immediately when the server receives the RST_STREAM frame, before any other data from that TCP connection is processed. Abuse of this feature is called a Rapid Reset attack because it relies on the ability for an endpoint to send a RST_STREAM frame immediately after sending a request frame, which makes the other endpoint start working and then rapidly resets the request. The request is canceled, but leaves the HTTP/2 connection open. The HTTP/2 Rapid Reset attack built on this capability is simple: The client opens a large number of streams at once as in the standard HTTP/2 attack, but rather than waiting for a response to each request stream from the server or proxy, the client cancels each request immediately. The ability to reset streams immediately allows each connection to have an indefinite number of requests in flight. By explicitly canceling the requests, the attacker never exceeds the limit on the number of concurrent open streams. The number of in-flight requests is no longer dependent on the round-trip time (RTT), but only on the available network bandwidth. In a typical HTTP/2 server implementation, the server will still have to do significant amounts of work for canceled requests, such as allocating new stream data structures, parsing the query and doing header decompression, and mapping the URL to a resource. For reverse proxy implementations, the request may be proxied to the backend server before the RST_STREAM frame is processed. The client on the other hand paid almost no costs for sending the requests. This creates an exploitable cost asymmetry between the server and the client. Multiple software artifacts implementing HTTP/2 are affected. This advisory was originally ingested from the swift-nio-http2 repo advisory and their original conent follows. swift-nio-http2 specific advisory swift-nio-http2 is vulnerable to a denial-of-service vulnerability in which a malicious client can create and then reset a large number of HTTP/2 streams in a short period of time.

This can easily overwhelm an EventLoop and prevent it from making forward progress. swift-nio-http2 1.28 contains a remediation for this issue that applies reset counter using a sliding window. This constrains the number of stream resets that may occur in a given window of time. Clients violating this limit will have their connections torn down. This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors.

Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection.

This was addressed by adding a recursion limit while decoding the packet. ASA-2024-0013 Nested messages in a transaction can consume exponential cpu and memory on UnpackAny calls. Themax_tx_bytes sets a limit for external TX but is not applied for internal messages emitted by wasm contracts or a malicious validator block. This may result in a node crashing due to resource exhaustion. This was addressed by adding additional validation to prevent this condition. Patches The issues above are resolved in Cosmos SDK versions v0.47.15 or v0.50.11. Please upgrade ASAP.

Improper Input Validation Affected range <=0.47.8 Fixed version 0.47.9 CVSS Score 6.5 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H Description ASA-2024-003: Missing BlockedAddressed Validation in Vesting Module Component: Cosmos SDK Criticality: Low Affected Versions: Cosmos SDK versions <= 0.50.3; <= 0.47.8 Affected Users: Chain developers, Validator and Node operators Impact: Denial of Service Description A vulnerability was identified in the x/auth/vesting module, which can allow a user to create a periodic vesting account on a blocked address, for example a non-initialized module account. Additional validation was added to prevent creation of a periodic vesting account in this scenario. If this case is triggered, there is the potential for a chain halt if the uninitialized account in question is called by GetModuleAccount in Begin/EndBlock of a module. This combination of an uninitialized blocked module account is not common. Next Steps for Impacted Parties If your chain has uninitialized blocked module accounts, it is recommended to proactively initialize them, as they are often initialized during a chain migration or during init genesis. If you are a chain developer on an affected version of the Cosmos SDK, it is advised to update to the latest available version of the Cosmos SDK for your project. Once a patched version is available, it is recommended that network operators upgrade. A Github Security Advisory for this issue is available in the Cosmos-SDK repository. For more information about Cosmos SDK, see https://docs.cosmos.network/. This issue was found by Dongsam who reported it to the Cosmos Bug Bounty Program on HackerOne on January 30, 2024. If you believe you have found a bug in the Interchain Stack or would like to contribute to the program by reporting a bug, please see https://hackerone.com/cosmos. Addendum A variant trigger of this issue via the x/authz and x/feegrant modules was discovered by Richie who reported it to the Cosmos Bug Bounty Program on HackerOne on April 6th, 2024, and was subsequently fixed by the Cosmos SDK team on April 21st, 2024. The guidance for mitigating this additional variant is the same as the parent advisory, so it is suggested that all chains proactively initialize module accounts if they have not already done so.

Affected range <0.46 Fixed version 0.46 Description Component: Cosmovisor Criticality: Medium Affected Versions: Cosmovisor < v1.0.0 (distributed with Cosmos-SDK < 0.46) Affected Users: Validators and Node operators utilizing unsupported versions of Cosmovisor Impact: DOS, potential RCE on node depending on configuration An issue has been identified on unsupported versions of Cosmovisor which may result in a Denial of Service or Remote Code Execution path depending on configuration for a node or validator using the vulnerable version to manage their node. If a validator is utilizing an affected version of Cosmovisor with DAEMON_ALLOW_DOWNLOAD_BINARIES set to true, a non-default configuration, it may be possible for an attacker to trigger a Remote Code Execution path as well on the host. In this configuration it is recommended to immediately stop use of the DAEMON_ALLOW_DOWNLOAD_BINARIES feature, and then proceed with an upgrade of Cosmovisor. It is recommended that all validators utilizing unsupported versions of Cosmovisor to upgrade to the latest supported versions immediately. If you are utilizing a forked version of Cosmos-SDK, it is recommended to stop use of Cosmovisor until it is possible to update to a supported version of Cosmovisor, whether through your project’s fork, or directly compiled from the Cosmos-SDK. At the time of this advisory, the latest version of Cosmovisor is v1.5.0. Additionally, the Amulet team recommends that developers building chains powered by Cosmos-SDK share this advisory with validators and node operators to ensure this information is available to all impacted parties within their ecosystems. For more information about Cosmovisor, see https://docs.cosmos.network/main/tooling/cosmovisor This issue was discovered by Maxwell Dulin and Nathan Kirkland, who reported it to the Cosmos Bug Bounty Program. If you believe you have found a bug in the Interchain Stack or would like to contribute to the program by reporting a bug, please see https://hackerone.com/cosmos. How to tell if I am affected? Running the following command will output whether your cosmovisor version is vulnerable to this issue or not. Vulnerable to this issue: strings ./cosmovisor | grep -q "NEEDED at" && echo "vulnerable" || echo "NOT vulnerable" vulnerable NOT vulnerable to this issue: strings ./cosmovisor_new | grep -q "NEEDED at" && echo "vulnerable" || echo "NOT vulnerable" NOT vulnerable A Note from Amulet on the Security Advisory Process In the interest of timely resolution of this issue for validators and node operators, the Amulet team has chosen to use existing processes and resources for distributing security advisories within the Cosmos and Interchain Ecosystems. Stay tuned as we implement an improved, more robust security advisory distribution system that will provide equitable access to information about security issues in the Interchain Stack. Incomplete Internal State Distinction Affected range <=0.47.9 Fixed version 0.47.10 Description ASA-2024-005: Potential slashing evasion during re-delegation Component: Cosmos SDK Criticality: Low Affected Versions: Cosmos SDK versions <= 0.50.4; <= 0.47.9 Affected Users: Chain developers, Validator and Node operators Impact: Slashing Evasion Summary An issue was identified in the slashing mechanism that may allow for the evasion of slashing penalties during a slashing event. If a delegation contributed to byzantine behavior of a validator, and the validator has not yet been slashed, it may be possible for that delegation to evade a pending slashing penalty through re-delegation behavior. Additional validation logic was added to restrict this behavior. Next Steps for Impacted Parties If you are a chain developer on an affected version of the Cosmos SDK, it is advised to update to the latest available version of the Cosmos SDK for your project.

This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors.

cosmossdk.io/math 1.0.1 (golang) pkg:golang/cosmossdk.io/[email protected] Integer Overflow or Wraparound Affected range <=1.3.0 Fixed version 1.4.0 CVSS Score 8.7 CVSS Vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N Description Name: ASA-2024-010: Mismatched bit-length in sdk.Int and sdk.Dec can lead to panic Component: Cosmos SDK / Math Criticality: High (Considerable Impact, and Possible Likelihood per ACMv1.2) Affected versions: cosmossdk.io/math package versions <= math/v1.3.0 Affected users: Chain Builders + Maintainers, Validators Impact The bit-length in sdk.Int and sdk.Dec are not aligned, which may present a possible panic condition when interacting with Dec types in an Int context. This issue was resolved by aligning the max size between the data types in the cosmossdk.io/math package. This issue impacts consumers of the cosmossdk.io/math, which includes popular modules including IBC-Go and tokenfactory (permissionless). If your chain interacts with APIs in the cosmossdk.io/math package, or utilizes a module that consumes this library, it is advised to update to the latest version at the time of the patch release by updating your project's go.mod dependency for cosmossdk.io/math. The patch can be applied without a hard-fork, and with a version bump in a chain's go.mod file like the following: go.mod - cosmossdk.io/math v1.3.0 + cosmossdk.io/math v1.4.0 [!NOTE] When on a lower version than cosmossdk.io/math v1.3.0, please do a coordinated upgrade before upgrading to >= 1.3.0 Patches The new release of cosmossdk.io/math v1.4.0 resolves this issue. Chains that utilize the cosmossdk.io/math library or modules that utilize the cosmossdk.io/math library should update to avoid this condition.

This was addressed by adding a recursion limit while decoding the packet. ASA-2024-0013 Nested messages in a transaction can consume exponential cpu and memory on UnpackAny calls. Themax_tx_bytes sets a limit for external TX but is not applied for internal messages emitted by wasm contracts or a malicious validator block. This may result in a node crashing due to resource exhaustion. This was addressed by adding additional validation to prevent this condition. Patches The issues above are resolved in Cosmos SDK versions v0.47.15 or v0.50.11. Please upgrade ASAP.

github.com/cometbft/cometbft 0.38.12 (golang) pkg:golang/github.com/cometbft/[email protected] Improper Validation of Array Index Affected range >=0.38.0 <0.38.15 Fixed version 0.38.15 CVSS Score 8.3 CVSS Vector CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N Description Name: ASA-2024-011: Vote Extensions: Panic when receiving a Pre-commit with an invalid data Component: CometBFT Criticality: High (Considerable Impact, and Possible Likelihood per ACMv1.2) Affected versions: >= 0.38.x, unreleased v1.x and main development branches Affected users: Chain Builders + Maintainers, Validators Impact A CometBFT node running in a network with vote extensions enabled could produce an invalid Vote message and send it to its peers. The invalid field of the Vote message is the ValidatorIndex, which identifies the sender in the ValidatorSet running that height of consensus. This field is ordinarily verified in the processing of Vote messages, but it turns out that in the case of a Vote message of type Precommit and for a non-nil BlockID, a logic was introduced before this ordinary verification to handle the attached vote extension. This introduced logic (not present in releases prior to 0.38.x) does not double-check the validity of the ValidatorIndex field. The result is a panic in the execution of the node receiving and processing such message. Impact Qualification This condition requires the introduction of malicious code in the full node sending this Vote message to its peers. Namely, nodes running upstream code cannot produce invalid Vote messages, with non-existing ValidatorIndex. Moreover, networks utilizing default behavior, where vote extensions are not enabled, are not affected by this issue. Patches The new CometBFT release v0.38.15 fixes this issue. Unreleased code in the main and v1.x branches, and experimental code in the v0.38-experimental and v1.x-experimental branches are patched as well. Workarounds When the consensus code panics after receiving an invalid Vote message, the operator can identify the peer from which that message was received. This may require increasing the logging level of the consensus module. This peer can then be subsequently banned at the p2p layer as a temporary mitigation.

We'll add more detail once chains had a chance to upgrade.) Mitigations Apart from upgrading, it is recommended to not open the gRPC and REST APIs of validator nodes to the public internet. Use isolated and resource-constrained environments for running separate public RPC nodes instead. These can then easily be thrown away and replaced with new instances in case of problems. Applying the patch Official Wasmd patch The patch will be shipped in a wasmd release. You will also have to update libwasmvm if you build statically. If you already use the latest / close to latest wasmd, you can update more or less as follows: Check the current wasmd version: go list -m github.com/CosmWasm/wasmd Bump the github.com/CosmWasm/wasmd dependency in your go.mod to 0.53.2 (Cosmos SDK 0.50 compatible); go mod tidy; commit. If you use the static libraries libwasmvm_muslc.aarch64.a/libwasmvm_muslc.x86_64.a, make sure that you use the same version as your wasmvm version. Check the updated wasmd version: go list -m github.com/CosmWasm/wasmd and ensure you see 0.53.2. Follow your regular practices to deploy chain upgrades. To double check if the correct library version is loaded at runtime, use this query: <appd> query wasm libwasmvm-version. It must show 2.1.4. The patch is not consensus breaking if you are already using wasmvm 2.1.3. If you are instead using wasmvm 2.1.2, then upgrading to 2.1.4 includes the consensus breaking changes of 2.1.3. DIY Patch If you are unable to upgrade to the latest version, you can backport the wasmd patch to your version. The patch is available at Wasmd 0.53.2. However, if you are on an older version of wasmd, you will also be using a different version of wasmvm. We provide the required patches for wasmvm in versions 2.1.4, 2.0.5, 1.5.6. To upgrade using this method: Check the current wasmvm version: go list -m github.com/CosmWasm/wasmvm and upgrade to the closest patched version. Bump the github.com/CosmWasm/wasmvm dependency in your go.mod to the closest compatible patched version (either 2.1.4, 2.0.5 or 1.5.6); go mod tidy; commit. Apply the patch linked above to your version of wasmd. If you use the static libraries libwasmvm_muslc.aarch64.a/libwasmvm_muslc.x86_64.a, make sure that you use the same version as your wasmvm version. Follow your regular practices to deploy chain upgrades. To double check if the correct library version is loaded at runtime, use this query: <appd> query wasm libwasmvm-version. It must show 2.1.4, 2.0.5 or 1.5.6 and must be the same as the wasmvm version in your go.sum. The patch is not consensus breaking as long as you were using the previous patch version of wasmvm before.

Why are we adding this to the chain repo? wouldn't it make more sense in xion.js repo?

We already have a script that generates protobufs, why are we forking a second process to do the same?
