Unauthenticated shell 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 arbitrary shell commands without authentication. WriterHandle.getCmd concatenates the sessionPath HTTP parameter into a shell command that ShellExecutor executes without sufficient validation or escaping. No credentials or user interaction are required; successful exploitation runs commands with the web service account and permits data access, modification, or service interruption.
