Detailsinfo

A vulnerability was found in WWBN AVideo up to 29.0 and classified as critical. This issue affects the function exec of the file cloneServer.json.php. The manipulation of the argument url with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

WWBN AVideo is an open source video platform. In versions 29.0 and below, the `cloneServer.json.php` endpoint in the CloneSite plugin constructs shell commands using user-controlled input (`url` parameter) without proper sanitization. The input is directly concatenated into a `wget` command executed via `exec()`, allowing command injection. An attacker can inject arbitrary shell commands by breaking out of the intended URL context using shell metacharacters (e.g., `;`). This leads to Remote Code Execution (RCE) on the server. Commit 473c609fc2defdea8b937b00e86ce88eba1f15bb contains a fix.
