Serendipity serendipity_event_bbcode.php Script serendipity[charset] Parameter Local File Inclusion

medium Nessus Plugin ID 23752

Language:

Synopsis

The remote web server contains a PHP application that is affected by a local file inclusion issue.

Description

The 'plugins/serendipity_event_bbcode/serendipity_event_bbcode.php' script included with the version of Serendipity installed on the remote host fails to sanitize input to the 'serendipity[charset]' parameter before using it to include PHP code.

Provided PHP's 'register_globals' setting is enabled, an unauthenticated, remote attacker may be able to exploit this issue to view arbitrary files or to execute arbitrary PHP code on the remote host, subject to the privileges of the web server user id.

Note that several other scripts included in Serendipity are reportedly affected by the same issue, although Nessus has not checked them.

Solution

Upgrade to Serendipity version 1.0.4 or later.
