CWE ID 400


CVE-2023-40584 is a vulnerability affecting all versions of Argo CD starting from v2.4. The vulnerability lies in the repo-server component, which is susceptible to a Denial-of-Service attack vector. This occurs because the component does not validate the size of inner files in a user-controlled tar.gz file, allowing a malicious, low-privileged user to exploit the vulnerability and disrupt the system's functionality and availability. Additionally, another vulnerability exists where the repo-server does not check extracted file permissions before attempting to delete them. An attacker can craft a malicious tar.gz archive that prevents deletion of its inner files, further compromising the system. A patch has been released in versions 2.6.15, 2.7.14, and 2.8.3, and users are advised to upgrade to mitigate these vulnerabilities which pose a medium risk with high availability impact according to CVE scoring.
