Nessus contains a flaw that allows a reflected cross-site scripting (XSS) attack. This flaw exists because the Web GUI (nessusd_www_server.nbin) does not validate unspecified input to a GET parameter before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
