CVE-2022-41328 is a path traversal vulnerability in Fortinet FortiOS execute commands. Improper pathname restrictions allow a privileged, authenticated attacker to use crafted CLI commands to read and write arbitrary files on the underlying Linux system outside permitted directories. Arbitrary file modification can enable unauthorized code execution and persistent malware deployment. Affected releases include FortiOS 7.2.0–7.2.3, 7.0.0–7.0.9, and older 6.x releases. The vulnerability was exploited as a zero-day, including in attacks attributed to UNC3886.
