CVE-2022-41328Known exploitation

Privileged file read and write via CLI traversal

Published Mar 7, 2023 · Updated Oct 21, 2025

Path traversal in affected Fortinet FortiOS 6.0 through 7.2 releases allows local users to read and write underlying system files. The execute wireless-controller hs20-icon upload-icon CLI path accepts crafted traversal sequences, allowing a TFTP-fetched file to be written outside its intended directory. Exploitation requires privileged CLI access; observed attacks replaced system binaries, established persistence, and triggered protective boot failures.
