Detection & IOCsextracted from sources · hover to see the quote
- →Monitor for unexpected or unauthenticated inbound connections to TCP port 1050 on FortiNAC appliances; this is the inter-server communication port targeted by CVE-2023-33299 deserialization exploitation. ↗
- →Monitor for unexpected or unauthenticated inbound connections to TCP port 5555 on FortiNAC appliances; this port is targeted by the related CVE-2023-33300 command injection vulnerability. ↗
- →The vulnerability is exploitable by a remote, unauthenticated attacker via a specially crafted deserialization payload; inspect traffic to TCP/1050 for Java/object deserialization patterns (e.g., 'ac ed 00 05' magic bytes) as an indicator of exploitation attempts. ↗
- ·FortiNAC versions 8.x (8.3 through 8.8, all versions) are confirmed vulnerable and will NOT receive a patch; organizations running any 8.x version must upgrade to a non-affected release. ↗
- ·TCP ports 1050 and 5555 are inter-server communication ports not commonly exposed to the public internet; however, internal network exposure still poses significant risk and patching remains critical. ↗
