eGroupWare spellchecker.php Arbitrary Shell Command Execution

high Nessus Plugin ID 45023

Language:

Synopsis

The remote web server contains a CGI script that can be abused to execute arbitrary commands.

Description

The version of eGroupWare hosted on the remote web server fails to sanitize user-supplied input to the 'aspell_path' and/or 'spellchecker_lang' parameters of the 'spellchecker.php' script before passing it to a shell.

An unauthenticated, remote attacker can leverage these issues to execute arbitrary commands subject to the privileges under which the web server operates.

Note that the install likely has a cross-site scripting vulnerability, although Nessus has not checked for this.

Solution

Upgrade to eGroupWare 1.6.003 / eGroupWare version EPL 9.1.20100309 / 9.2.20100309 or later.
