Arbitrary directory exposure via path traversal
Published Nov 29, 2023 · Updated Aug 2, 2024
Path traversal in GL.iNet AX1800 3.215 and earlier allows remote authenticated users to expose arbitrary router directories over SMB. The Samba set API checks that a supplied path starts with /mnt/ without normalizing traversal segments, so /mnt/../tmp passes the check. An administrator token is required; successful exploitation makes files outside /mnt available through the configured network share.
