ACal embed/day.php path Parameter Remote File Inclusion

high Nessus Plugin ID 21557

Language:

Synopsis

The remote web server contains a PHP script that is affected by a remote file include issue.

Description

The remote host is running ACal, an open source, web-based event calendar written in PHP.

The version of ACal installed on the remote host fails to sanitize user-supplied input to the 'path' parameter of the 'embed/day.php' script before using it in PHP 'include()' functions. Provided PHP's 'register_globals' setting is enabled, an unauthenticated attacker may be able to exploit this issue to view arbitrary files on the remote host or to execute arbitrary PHP code, possibly taken from third-party hosts.

Solution

Unknown at this time.
