What it detects

This rule detects POST or M-POST requests to the Citrix Session Recording broker rem endpoints carrying a SOAPAction header. This maps to the .NET deserialization vulnerability where crafted SOAP requests to the RestApiStat and Player broker interfaces execute arbitrary code. An attacker uses this to gain remote code execution on the session recording server.
