Detailsinfo

A vulnerability, which was classified as problematic, was found in argoproj argo-cd up to 2.8.13/2.9.9/2.10.4. Affected is the function loadRepoIndex. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. 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. A patch for this vulnerability has been released in v2.10.3, v2.9.8, and v2.8.12.

The advisory is available at github.com. This vulnerability is traded as CVE-2024-29893 since 03/21/2024. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.
