Icinga 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 URL upon submission to the cgi-bin/status.cgi script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
