Description Jan Lieskovsky 2012-04-22 17:09:33 UTC

A cross-site scripting (XSS) and cross-site request forgery (CSRF) flaws were found in the way DokuWiki, a standards compliant, simple to use Wiki, performed sanitization of the 'target' parameter when preprocessing edit form data. A remote attacker could provide a specially-crafted URL, which once visited by a valid DokuWiki user would lead to arbitrary HTML or web script execution in the context of logged in DokuWiki user.
