An on-path attacker who can observe cleartext UDP traffic can inject arbitrary packets into any established session by forging the two-byte connection identifier, enabling session termination via TerminateConnectionPacket, arbitrary channel message forgery, and forged request responses without requiring IP address spoofing.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":32,"depthScoreParts":{"impact":32.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
