Description

ViewVC contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate input passed via the 'function name' line within the diff function in lib/viewvc.py before returning it to the user. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
