  • →Check for the Windows Message Queuing service running and TCP port 1801 actively listening — both conditions must be true for a host to be exploitable. ↗
  • →Exploitation requires the Windows Message Queuing (MSMQ) service to be enabled; hunt for unexpected enablement of this service on internet-facing or PGM Server hosts. ↗
  • →Trigger condition is a specially crafted file sent over the network to a PGM Server environment with MSMQ running; monitor for anomalous inbound network traffic to TCP/1801 from untrusted sources. ↗
  • ·The Talos Snort rule set covers multiple November 2023 Patch Tuesday CVEs, not exclusively CVE-2023-36397; confirm which specific rule IDs map to this CVE before deploying. ↗
