Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 41.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 CM-6 (Configuration Settings) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2025-25685 is a path traversal vulnerability (CWE-22) discovered in the GL-INet Beryl AX GL-MT3000 router running firmware version v4.7.0. The flaw allows attackers to download arbitrary files from the device's file system by creating symbolic links on an external drive configured as a Samba share. It has a CVSS v3.1 base score of 7.5, reflecting high confidentiality impact with network accessibility, low attack complexity, and no requirements for privileges or user interaction.

Attackers can exploit this vulnerability remotely without authentication by mounting an external drive as a Samba share on the router and manipulating symbolic links to traverse the file system paths. Successful exploitation enables unauthorized access to sensitive files on the device, such as configuration data or logs, potentially exposing credentials, network details, or other critical information.

References to the vulnerability include a Medium article detailing multiple path traversal issues in the Beryl AX GL-MT3000 router.
