Description

Impact

A vulnerability was found in Argo CD that allows an attacker to spoof error messages on the login screen when SSO is enabled.

In order to exploit this vulnerability, an attacker would have to trick the victim to visit a specially crafted URL which contains the message to be displayed.

As far as the research of the Argo CD team concluded, it is not possible to specify any active content (e.g. Javascript) or other HTML fragments (e.g. clickable links) in the spoofed message.

Patched versions

A patch for this vulnerability has been released in the following Argo CD versions:

  • v2.3.4
  • v2.2.9
  • v2.1.15

Workarounds

No workaround available.

Mitigations

It is advised to update to an Argo CD version containing a fix for this issue (see Patched versions above).

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
