CVE-2026-10141: TOTOLINK X2000R unsigned firmware in boa web interface

CVE-2026-10141 · Severity: critical · CVSS 9.1 · Published 2026-10-20

The TOTOLINK X2000R is a budget gigabit home router commonly used in Asia. An authenticated attacker can upload a specially crafted firmware binary to bypass signature verification, allowing arbitrary code execution on the device. This could give an attacker complete control over the router, enabling network interception, DNS hijacking, or using it as an attack platform against connected devices.

Technologies: TOTOLINK X2000r. Vendors: TOTOLINK.

Technical details

The vulnerability is an improper verification of cryptographic signatures (CWE-347) in the boa firmware update functionality. An authenticated HTTP POST request to /boafrm/formUpload can submit a firmware image that bypasses signature verification in the handleFirmwareFile function. The firmware update process does not properly validate the cryptographic integrity of the firmware partition, allowing an attacker to flash arbitrary code with the privileges of the web server process.
