Omer Singer has discovered multiple vulnerabilities in WikyBlog, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "key" parameter in index.php/Special/Main/keywordSearch, to the "revNum" parameter in index.php/Edit/Main/Home, to the "to" parameter in index.php/Special/Main/WhatLinksHere, to the "user" parameter in index.php/Special/Main/UserEdits, and appended after "index.php/" is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in the context of an affected site.
These vulnerabilities have been confirmed in version 1.7.1 RC2. Prior versions may also be affected.
Solution: Update to version 1.7.1.
