CVE-2022-42470

Local code execution via named-pipe path traversal

Published Apr 11, 2023 · Updated Oct 23, 2024

Relative path traversal in Fortinet FortiClient for Windows allows local users to execute unauthorized code via a named-pipe request. The named-pipe request handler fails to restrict attacker-controlled relative paths, allowing file creation outside its intended directory. A low-privileged local account must reach the pipe; successful exploitation permits code or command execution without user interaction.
