CVE-2022-22167 – Junos OS: SRX Series: If no-syn-check is enabled, traffic classified as UNKNOWN gets permitted by pre-id-default-policy
https://notcve.org/view.php?id=CVE-2022-22167
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. While JDPI correctly classifies out-of-state asymmetric TCP flows as the dynamic-application UNKNOWN, this classification is not provided to the policy module properly and hence traffic continues to use the pre-id-default-policy, which is ... • https://kb.juniper.net/JSA11265 • CWE-863: Incorrect Authorization •
