CVE-2021-43070Network attack vector

Authenticated file disclosure via relative path traversal

Published Mar 2, 2022 · Updated Oct 22, 2024

Path traversal in Fortinet FortiWLM 8.6.2 and earlier allows remote authenticated users to read arbitrary filesystem files. Fortinet has not disclosed the affected handlers or how crafted relative paths escape the intended directory before file retrieval. Successful exploitation requires valid management-interface credentials and exposes files readable by the FortiWLM service without changing or deleting them.
