CVE-2025-25685Public exploitNetwork attack vector

Arbitrary file read via Samba share symlinks

Published Mar 17, 2025 · Updated Mar 21, 2025

Path traversal in GL.iNet Beryl AX GL-MT3000 4.7.0 allows attackers to read arbitrary device files through an enabled Samba share. The router follows symbolic links placed in a shared directory on an ext4 USB drive, and the mobile application downloads each link target without confining resolution to the shared directory. Exploitation requires a prepared ext4 drive connected to the router, an enabled Samba share for its directory, and access through the mobile application; exposed files are readable but not modified.
