Vulnerability Assessment Details

Guestbook Script include_files Parameter Remote File Include Vulnerability

Vulnerability Assessment Summary
Tries to read /etc/passwd using Guestbook Script

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP application that is affected by
remote file include issues.

Description :

The remote host is running Guestbook Script, a free guestbook written
in PHP.

The version of Guestbook Script installed on the remote host fails to
sanitize input to the 'include_files' array parameter before using it
in a PHP 'include()' function in various scripts. 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.

Note that the application must be running under PHP 5 for a possible hacker
to take code from third-party hosts.
