CVE-2025-15500Public exploitNetwork attack vector

Unauthenticated command execution via sessionPath concatenation

Published Jan 9, 2026 · Updated Jan 9, 2026

OS command injection in Sangfor OSM 3.0.0 through 3.0.8 allows remote attackers to execute commands through a crafted POST request. WriterHandle.getHis passes the sessionPath parameter to WriterHandle.getCmd, which concatenates it into a shell command executed by ShellExecutor. No authentication or user interaction is required, and injected shell metacharacters run commands with the web service account's privileges.
