CVE-2022-33962

Self IP access-control bypass via iRules commands

Published Aug 4, 2022 · Updated Sep 17, 2024

Access-control bypass in F5 BIG-IP allows local users to reach restricted self IP services through certain iRules commands. F5 identifies the locus only as certain iRules commands; it has not disclosed the affected commands or faulty authorization operation. Exploitation requires local access with high privileges and circumvents port lockdown, exposing services that a self IP was configured to reject.
