CVE-2023-22657

Command execution via crafted tenant file names

Published Feb 1, 2023 · Updated Mar 26, 2025

Command injection in F5 F5OS-A 1.2.0 to before 1.3.0 and F5OS-C 1.3.0 to before 1.5.0 allows local users to execute commands. The tenant-file processing path passes attacker-controlled file-name content into a command context, but F5 has not disclosed the responsible handler or parsing operation. Exploitation requires local access, user interaction, and high-complexity conditions; injected commands can read or alter appliance data and interrupt service.
