Remote command execution via unsanitized upload filename
Published Jan 9, 2026 · Updated Jan 9, 2026
OS command injection in Sangfor OSM 3.0.0 through 3.0.8 allows remote authenticated users to execute arbitrary system commands. The uploadCN method in VersionController.java passes an escaped multipart filename into a concatenated bash command, but its filter leaves shell metacharacters usable. A low-privileged account can reach the upload endpoint; injected commands run with the application service account and can read, alter, or interrupt the host.
