Cross-site Scripting in Malcolm

A web interface reflects a portion of the request URL into a script context and a hyperlink attribute without adequate encoding, and does not require authentication to reach. This allows an unauthenticated network attacker to craft a link that, when visited by a user, executes arbitrary script in the context of the affected application and can redirect the user's browser to an arbitrary external site. Successful exploitation could allow an attacker to act with the compromised user's session privileges within the application.
