CVE-2026-29058 Details
Description
AVideo is a video-sharing Platform software. Prior to version 7.0, an unauthenticated attacker can execute arbitrary OS commands on the server by injecting shell command substitution into the base64Url GET parameter. This can lead to full server compromise, data exfiltration (e.g., configuration secrets, internal keys, credentials), and service disruption. This issue has been patched in version 7.0.
A vulnerability allowing unauthenticated OS command injection has been identified in AVideo versions prior to 7.0. The issue arises in the 'objects/getImage.php' file, where the 'base64Url' GET parameter is decoded and directly interpolated into a double-quoted 'ffmpeg' shell command without adequate escaping. This flaw can be exploited to execute arbitrary commands on the server, potentially leading to a full server compromise, unauthorized data access (including configuration secrets, internal keys, and credentials), and disruption of services.
Users are advised to update to AVideo version 7.0 or later. Additionally, access to 'objects/getImage.php' can be restricted at the web server or reverse proxy level, and Web Application Firewall (WAF) rules can be applied to block suspicious patterns until the update is deployed.
