DokuWiki Spell Checker Embedded Link Arbitrary PHP Code Execution

high Nessus Plugin ID 21662

Language:

Synopsis

The remote web server contains a PHP application that is affected by an arbitrary code execution vulnerability.

Description

The remote host is running DokuWiki, an open source wiki application written in PHP.

The installed version of DokuWiki fails to properly sanitize input to the 'data' parameter of the 'lib/exe/spellcheck.php' script before evaluating it to handle links embedded in the text. An unauthenticated attacker can leverage this issue with PHP commands in 'complex curly syntax' to execute arbitrary PHP code on the remote host subject to the privileges of the web server user id.

Solution

Upgrade to DokuWiki release 2006-03-09 with hotfix 823 or later.
