How to Fix CVE-2024-29893

To remediate this vulnerability, upgrade all affected Github.com/argoproj/argo cd/v2 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/v2 fixed: 2.8.14
Upgrade github.com/argoproj/argo-cd/v2 to 2.8.14
github.com/argoproj/argo-cd/v2 fixed: 2.9.10
Upgrade github.com/argoproj/argo-cd/v2 to 2.9.10
github.com/argoproj/argo-cd/v2 fixed: 2.10.5
Upgrade github.com/argoproj/argo-cd/v2 to 2.10.5
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/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-29893, inspect your project dependencies for Github.com/argoproj/argo cd/v2:

inspect dependencies for github.com/argoproj/argo-cd/v2

Analyze the terminal output to locate any version of Github.com/argoproj/argo cd/v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.8.14), 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Github.com/argoproj/argo cd/v2, 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 versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, it's possible to crash the repo server component through an out of memory error by pointing it to a malicious Helm registry. The loadRepoIndex() function in the ArgoCD's helm package, does not limit the size nor time while fetching the data. It fetches it and creates a byte slice from the retrieved data in one go. If the registry is implemented to push data continuously, the repo server will keep allocating memory until it runs out of it. ### Patches A patch for this vulnerability has been released in the following Argo CD versions: v2.10.5 v2.9.10 v2.8.14 ### For more information If you have any questions or comments about this advisory: 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 ### Credits This vulnerability was found & reported by Jakub Ciolek The Argo team would like to thank these contributors for their responsible disclosure and constructive communications during the resolve of this issue
