Vulnerability details

The vulnerability allows an unauthenticated remote attacker to bypass PostgreSQL query rules and request logging for an affected flow.

The vulnerability exists due to failed recovery in Suricata's PostgreSQL parser when valid PostgreSQL traffic follows a to-server TCP reassembly gap. An unauthenticated remote attacker can send valid PostgreSQL traffic after such a gap to permanently disable request inspection for that flow in deployments with PostgreSQL parsing enabled.
