The developers of the Python-based MoinMoin Wiki system have closed two XSS vulnerabilities and a directory traversal hole. Insufficient filtering of submitted user names in the action/ login script allowed injected JavaScript code to be executed in the victim's browser. The same applied to the action/ file upload script containing JavaScript in the message, pagename and target parameters.

A directory traversal hole was reported to allow attackers to use specially crafted cookies to traverse the data/user/ directory and compromise systems by overwriting files. The flaw occurred in the script when processing certain IDs in the cookie. Only version 1.5.x contained the latter vulnerability. Apart from the updated version 1.6.1, the developers have also made patches for 1.6 and 1.5.x available for download.
