CVE-2023-40584

Summary

CVE-2023-40584 affects all versions of Argo CD starting from v2.4, introducing a Denial-of-Service vulnerability in the ArgoCD repo-server component. Malicious users can exploit this by sending oversized tar.gz files, potentially harming system functionality and availability. An additional vulnerability arises from the component's failure to check extracted file permissions before attempting deletion, enabling attackers to craft malicious tar.gz archives that prevent the deletion of inner files during manifest generation. Users are advised to upgrade to versions 2.6.15, 2.7.14, or 2.8.3, or implement Role-Based Access Control to limit administrator access to trusted Helm charts.
