+title: Camaleon CMS vulnerable to remote code execution through code injection (GHSL-2024-185)
+date: 2024-09-23
+description: |
+  The [actions](https://github.com/owen2345/camaleon-cms/blob/feccb96e542319ed608acd3a16fa5d92f13ede67/app/controllers/camaleon_cms/admin/media_controller.rb#L51-L52) defined inside of the MediaController class do not check whether a given path is inside a certain path (e.g. inside the media folder). If an attacker performed an account takeover of an administrator account (See: GHSL-2024-184) they could delete arbitrary files or folders on the server hosting Camaleon CMS. The [crop_url](https://github.com/owen2345/camaleon-cms/blob/feccb96e542319ed608acd3a16fa5d92f13ede67/app/controllers/camaleon_cms/admin/media_controller.rb#L64-L65) action might make arbitrary file writes (similar impact to GHSL-2024-182) for any authenticated user possible, but it doesn't seem to work currently.
+
+  Arbitrary file deletion can be exploited with following code path:
+  The parameter folder flows from the actions method:
+  ```ruby
+    def actions
+      authorize! :manage, :media if params[:media_action] != 'crop_url'
+      params[:folder] = params[:folder].gsub('//', '/') if params[:folder].present?
+      case params[:media_action]
+      [..]
+      when 'del_file'
+        cama_uploader.delete_file(params[:folder].gsub('//', '/'))
+        render plain: ''
+  ```
+  into the method delete_file of the CamaleonCmsLocalUploader
+  class (when files are uploaded locally):
+  ```ruby
+  def delete_file(key)
+    file = File.join(@root_folder, key)
+    FileUtils.rm(file) if File.exist? file
+    @instance.hooks_run('after_delete', key)
+    get_media_collection.find_by_key(key).take.destroy
+  end
+  ```
+  Where it is joined in an unchecked manner with the root folder and
+  then deleted.
+
+  ## Proof of concept
+  The following request would delete the file README.md in the top folder of the Ruby on Rails application. (The values for auth_token, X-CSRF-Token and _cms_session would also need to be replaced with authenticated values in the curl command below)
+  ```
+  curl --path-as-is -i -s -k -X $'POST' \
+      -H $'X-CSRF-Token: [..]' -H $'User-Agent: Mozilla/5.0' -H $'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' -H $'Accept: */*' -H $'Connection: keep-alive' \
+      -b $'auth_token=[..]; _cms_session=[..]' \
+      --data-binary $'versions=&thumb_size=&formats=&media_formats=&dimension=&private=&folder=..
+  2F..
+  2F..
+  2FREADME.md&media_action=del_file' \
+      $'https://<camaleon-host>/admin/media/actions?actions=true'
+  ```
+
+  ## Impact
+
+  This issue may lead to a defective CMS or system.
+
+  ## Remediation
+
+  Normalize all file paths constructed from untrusted user input before using them and check that the resulting path is inside the
+  targeted directory. Additionally, do not allow character sequences such as .. in untrusted input that is used to build paths.

+title: Use-after-free in libxml2 via Nokogiri::XML::Reader
+date: 2024-03-18
+description: |
+  ### Summary
+
+  Nokogiri upgrades its dependency libxml2 as follows:
+  - v1.15.6 upgrades libxml2 to 2.11.7 from 2.11.6
+  - v1.16.2 upgrades libxml2 to 2.12.5 from 2.12.4
+
+  libxml2 v2.11.7 and v2.12.5 address the following vulnerability:
+
+  CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062
+  - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604
+  - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970
+
+  Please note that this advisory only applies to the CRuby implementation of Nokogiri, and only if
+  the packaged libraries are being used. If you've overridden defaults at installation time to use
+  system libraries instead of packaged libraries, you should instead pay attention to your distro's
+  libxml2 release announcements.
+
+  JRuby users are not affected.
+
+  ### Severity
+
+  The Nokogiri maintainers have evaluated this as **Moderate**.
+
+  ### Impact
+
+  From the CVE description, this issue applies to the `xmlTextReader` module (which underlies
+  `Nokogiri::XML::Reader`):
+
+  > When using the XML Reader interface with DTD validation and XInclude expansion enabled,
+  > processing crafted XML documents can lead to an xmlValidatePopElement use-after-free.
+
+  ### Mitigation
+
+  Upgrade to Nokogiri `~> 1.15.6` or `>= 1.16.2`.
+
+  Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile
+  and link Nokogiri against patched external libxml2 libraries which will also address these same
+  issues.
