CVE-2026-10132
CriticalCVSS 9.1Summary
A stack-based buffer overflow vulnerability exists in the boa formIpQos mac functionality of X2000R (TOTOLINK-X2000R-Gh-V1.0.0-B20250421.1327). A specially crafted HTTP request can lead to arbitrary code execution. An attacker can trigger this vulnerability with an authenticated HTTP request.
Risk Assessment
An authenticated attacker can remotely execute arbitrary code on the device and take control of it. This can lead to full compromise of confidentiality and integrity of the network where the router operates.
Recommendation
Update X2000R firmware to a version free of the vulnerability or apply the vendor patch. Until then, restrict access to the administrative interface and change default credentials.
