This affects various Junos OS versions prior to specified releases. The vulnerability has a CVSS score of 5.3 (Medium), indicating a network-based attack with low complexity, requiring no user interaction. The potential impact is a bypass of intended security policies, leading to a loss of integrity as packets that should be blocked are allowed.

It is not listed in CISA's KEV catalog.
