CVE-2026-10141
CriticalCVSS 9.1Summary
An unsigned firmware vulnerability exists in the boa Firmware Update functionality of X2000R (version TOTOLINK-X2000R-Gh-V1.0.0-B20250421.1327). A specially crafted firmware binary can lead to arbitrary firmware update. An attacker can make an authenticated HTTP request to trigger this vulnerability.
Risk Assessment
An authenticated attacker can upload unsigned, malicious firmware, gaining full control of the device. This may lead to persistent compromise of the router and the network.
Recommendation
Update the device firmware to a fixed version if the vendor provides one. Until then, restrict access to the administrative interface and change default credentials.
