Detection & IOCsextracted from sources · hover to see the quote

  • →Detect WebDAV PROPFIND requests with Content-Type: text/xml targeting IIS — a large XML body with many attributes on elements is the attack vector for this DoS. ↗
  • →Monitor for repeated PROPFIND requests in a loop from a single source to the same IIS host/port, indicative of the blowout DoS pattern used in the PoC exploit. ↗
  • ·Vulnerability affects IIS versions 5.0, 5.1, and 6.0 only; the WebDAV Message Handler must be enabled for the attack surface to be exposed. ↗
  • ·The DoS impact includes memory and CPU exhaustion as well as application crash — detection should also include resource utilization monitoring on IIS worker processes. ↗
