Vulnerability Title
WWBN AVideo: Authenticated Arbitrary File Read in view/update.php
Source: CVE Program / CVE List V5
Vulnerability Description
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.
