urlhttp://[email protected]/SomeNonExistantPath
  • Detect XSS exploitation attempts against IIS error pages by monitoring HTTP requests where the URL userinfo component (user@ syntax) contains a script URI or external domain reference, e.g. 'http://script@<target>/NonExistentPath' pattern.
  • Monitor for theft of cookie-based authentication credentials from Microsoft domains (e.g. Hotmail, Passport) as a downstream indicator of successful exploitation.
  • Flag HTTP requests to IIS servers containing a non-existent path combined with a userinfo (@ symbol) in the URL, which is the attack delivery mechanism for this CVE.
  • ·The vulnerability is in IIS itself (versions 4.0, 5.0, 5.1), not in Cisco products; Cisco products are affected only because they are installed on Windows systems running IIS.
  • ·The XSS payload executes within the context of the vulnerable site's origin, meaning cookie and session data scoped to that domain are at risk.
