CVE-2021-44167

Sensitive log disclosure via symbolic links

Published May 11, 2022 · Updated Oct 22, 2024

Incorrect resource permissions in Fortinet FortiClient Linux 7.0.2 and earlier allow local users to read sensitive logs via symbolic links. Symbolic links redirect access through incorrectly protected log files and directories, but Fortinet has not identified the affected paths or operation. The attacker needs local filesystem access to place the links, and the documented consequence is disclosure of sensitive data.
