How do I check whether I am affected by CVE-2026-10132?

In the router admin UI (System/Status page) read the firmware version. If it is TOTOLINK-X2000R-Gh-V1.0.0-B20250421.1327 you are affected. Also check whether the admin interface is reachable from WAN (remote management setting).

What is the fix for CVE-2026-10132?

No fixed firmware published as of 2026-10-23. Mitigate: turn off WAN/remote management, restrict the admin UI to a trusted LAN, change the default admin password to a strong unique one, and check totolink.net downloads for X2000R firmware newer than B20250421.1327.

TOTOLINK X2000R router: stack overflow in web setup lets attackers run code

Authenticated stack-based buffer overflow in the boa web server's formIpQos handler on the TOTOLINK X2000R. The 'mac' POST parameter (used with sqosadvAdd=1) is strcpy'd into a 0x22-byte stack buffer. A logged-in attacker gets code execution as root-level boa process. Talos reproduced control of the PC. CVSS 9.1. No vendor patch is published.

Summary written from the sources below. Check the originals before acting.
