CVE-2022-22157 – Junos OS: SRX Series: Traffic classification vulnerability when 'no-syn-check' is enabled
https://notcve.org/view.php?id=CVE-2022-22157
19 Jan 2022 — A traffic classification vulnerability in Juniper Networks Junos OS on the SRX Series Services Gateways may allow an attacker to bypass Juniper Deep Packet Inspection (JDPI) rules and access unauthorized networks or resources, when 'no-syn-check' is enabled on the device. JDPI incorrectly classifies out-of-state asymmetric TCP flows as the dynamic-application INCONCLUSIVE instead of UNKNOWN, which is more permissive, causing the firewall to allow traffic to be forwarded that should have been denied.
