Synopsis

The remote web server hosts a PERL module that is affected by a directory traversal vulnerability.

Description

The remote host appears to be using the CGI::Session PERL module to manage file-based sessions.

The version of this module hosted by the remote web server fails to properly sanitize input to the session cookie of directory traversal sequences. An unauthenticated, remote attacker can leverage this issue on a Windows system to bypass session-based controls.
