Detailsinfo

A vulnerability was found in WWBN AVideo up to 29.0. It has been rated as critical. This issue affects an unknown code of the file view/update.php. The manipulation of the argument updateFile with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

WWBN AVideo is an open source video platform. In 29.0 and earlier, view/update.php reads $_POST['updateFile'] as a relative path under updatedb/ and passes it to PHP's file() for line-by-line execution as part of a database migration. An authenticated administrator can abuse this to read arbitrary text files reachable from the web-server process.
