Arbitrary file reads via path traversal
Published May 5, 2022 · Updated Sep 17, 2024
Directory traversal in F5 BIG-IP allows remote authenticated users to read arbitrary files through management interfaces. Undisclosed iControl REST endpoints and TMOS Shell commands in Guided Configuration fail to confine attacker-supplied paths to intended directories. Exploitation requires network access and at least the resource administrator role, and the documented consequence is file disclosure without integrity or availability impact.
