CVE-2026-1413Public exploitNetwork attack vector

Authenticated command execution via unvalidated port parameter

Published Jan 26, 2026 · Updated Jan 26, 2026

Command injection in Sangfor OSM 3.0.0 through 3.0.12 allows remote authenticated users to execute OS commands via a crafted port value. The portValidate method appends the POST port value to a bash invocation of nmap_port.sh after blocking only one literal string. A valid FORTSESSIONID is required, and shell metacharacters in port run arbitrary commands with the service's operating-system privileges.
