Technical Analysis
CVE-2026-10137 describes a stack-based buffer overflow vulnerability in the formUpload() function of the TOTOLINK X2000R router firmware version TOTOLINK-X2000R-Gh-V1.0.0-B20250421.1327. An attacker with authenticated HTTP access can send a specially crafted request to exploit this vulnerability, leading to arbitrary code execution. The vulnerability has a CVSS 3.1 base score of 9.1, indicating critical severity with network attack vector, low attack complexity, required privileges, no user interaction, and impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary code on the affected device, compromising system confidentiality, integrity, and availability. This can lead to full control over the device and potential further network compromise.
Mitigation Recommendations
No patch or official remediation information is currently available. Users should monitor vendor advisories for updates. Until a fix is released, restrict authenticated access to the device's HTTP interface to trusted users only and consider additional network-level protections to limit exposure.
