Privilege escalation via traversal in file renaming
Published Dec 8, 2025 · Updated Dec 8, 2025
Path traversal in Yottamaster DM2 and DM3 through 1.9.12 and DM200 through 1.2.23 allows remote authenticated users to move files. The renaming feature accepts path input without directory-traversal checks, allowing file operations outside the caller's permitted directory. Low-privileged access is required, and successful exploitation changes file placement across horizontal or vertical privilege boundaries.
