Description

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Security Summary

CVE-2025-12622 is a buffer overflow vulnerability affecting the Tenda AC10 router running firmware version 16.03.10.13. The flaw exists in the formSysRunCmd function of the /goform/SysRunCmd file, where manipulation of the "getui" argument triggers the buffer overflow. It is classified under CWE-119 and CWE-120, with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.

The vulnerability enables remote exploitation by attackers who possess low privileges, such as authenticated users with network access. Exploitation requires low attack complexity and no user interaction, allowing adversaries to achieve high confidentiality, integrity, and availability impacts. This could result in arbitrary code execution, data leakage, system modification, or denial of service on the affected device.

MITRE ATT&CK Enterprise Techniques

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

The remote buffer overflow vulnerability in the Tenda AC10 router's web management interface (/goform/SysRunCmd) allows unauthenticated attackers to potentially achieve remote code execution by exploiting a public-facing application.
