How to Fix CVE-2022-31035

To remediate this vulnerability, upgrade all affected Github.com/argoproj/argo cd dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/argoproj/argo-cd fixed: 2.1.16
Upgrade github.com/argoproj/argo-cd to 2.1.16
github.com/argoproj/argo-cd/v2 fixed: 2.1.16
Upgrade github.com/argoproj/argo-cd/v2 to 2.1.16
github.com/argoproj/argo-cd/v2 fixed: 2.2.10
Upgrade github.com/argoproj/argo-cd/v2 to 2.2.10
github.com/argoproj/argo-cd/v2 fixed: 2.3.5
Upgrade github.com/argoproj/argo-cd/v2 to 2.3.5
github.com/argoproj/argo-cd/v2 fixed: 2.4.1
Upgrade github.com/argoproj/argo-cd/v2 to 2.4.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/argoproj/argo-cd

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-31035, inspect your project dependencies for Github.com/argoproj/argo cd:

inspect dependencies for github.com/argoproj/argo-cd

Analyze the terminal output to locate any version of Github.com/argoproj/argo cd in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.16), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Github.com/argoproj/argo cd, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact All unpatched versions of Argo CD starting with v1.0.0 are vulnerable to a cross-site scripting (XSS) bug allowing a malicious user to inject a `javascript:` link in the UI. When clicked by a victim user, the script will execute with the victim's permissions (up to and including admin). The script would be capable of doing anything which is possible in the UI or via the API, such as creating, modifying, and deleting Kubernetes resources. ### Patches A patch for this vulnerability has been released in the following Argo CD versions: * v2.4.1 * v2.3.5 * v2.2.10 * v2.1.16 ### Workarounds There are no completely-safe workarounds besides upgrading. **Mitigations:** 1. Avoid clicking external links presented in the UI. Here is an example of an Application node with an external link: ![Application node in the Argo CD UI with an external link](https://user-images.githubusercontent.com/350466/171678146-026bbf20-2116-4b9f-8af8-7bb5b7ee8dff.png) The link's title is user-configurable. So even if you hover the link, and the tooltip looks safe, the link might be malicious. The only way to be certain that the link is safe is to inspect the page's source. 2. Carefully limit who has permissions to edit resource manifests (this is configured in [RBAC](https://argo-cd.readthedocs.io/en/stable/operator-manual/rbac/)). ### References * [Documentation for the external links feature](https://argo-cd.readthedocs.io/en/stable/user-guide/external-url/) ### Credits Disclosed by ADA Logics in a security audit of the Argo project sponsored by CNCF and facilitated by OSTIF. Thanks to Adam Korczynski and David Korczynski for their work on the audit. ### For more information * Open an issue in [the Argo CD issue tracker](https://github.com/argoproj/argo-cd/issues) or [discussions](https://github.com/argoproj/argo-cd/discussions) * Join us on [Slack](https://argoproj.github.io/community/join-slack) in channel #argo-cd
