Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability is triggered via a specially crafted SOAP request to the WS-Addressing plugin in gSOAP; monitor for malformed/unexpected WS-Addressing headers in inbound SOAP/HTTP traffic.
  • The vulnerable component is the WS-Addressing plugin functionality of Genivia gSOAP 2.8.107; flag or audit deployments running this specific version.
  • Attack is delivered over HTTP and is remotely exploitable with no authentication required (CVSS 9.8); prioritize perimeter detection on HTTP-exposed gSOAP services.
  • ·The vulnerability specifically requires the WS-Addressing plugin to be enabled in gSOAP; deployments not using this plugin are not affected.
  • ·Debian tracking shows the issue remains open across multiple releases (bookworm, bullseye, forky, sid, trixie) as of the last update; patch availability should be verified per distribution.
