What it detects

This rule detects POST requests to the Workspace ONE Access embedded auth broker callback endpoint used in the CVE-2022-22972 host header authentication bypass. This maps to exploitation where an attacker supplies a crafted Host header to trick the internal auth broker into issuing a valid session. Successful abuse grants unauthenticated administrative access to the appliance.
