DokuWiki spellcheck Arbitrary Code Execution Vulnerability

Vulnerability Assessment Summary
Executes arbitrary PHP code via DocuWiki spellcheck

Detailed Explanation for this Vulnerability Assessment

Summary :

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 rights of the web server user id.
