Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly remediates the buffer overflow vulnerability in the formWifiWpsOOB function through timely application of vendor firmware patches.

prevent

Implements memory protections such as address space layout randomization and stack canaries to mitigate exploitation of the buffer overflow for arbitrary code execution.

prevent

Requires validation of inputs to the formWifiWpsOOB function to reject oversized or malformed data that could trigger the buffer overflow.

MITRE ATT&CK Enterprise TechniquesAI

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 buffer overflow in the router's web form (/goform/WifiWpsOOB) enables remote exploitation of a public-facing application via crafted HTTP POST requests, potentially leading to code execution or denial of service.

NVD Description

Tenda AC6 v15.03.05.16 was discovered to contain a buffer overflow via the formWifiWpsOOB function.

Deeper analysisAI

CVE-2025-29030 is a buffer overflow vulnerability (CWE-787) affecting Tenda AC6 routers running version v15.03.05.16. The flaw resides in the formWifiWpsOOB function and was published on 2025-03-14T14:15:18.200. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its potential for severe impact.

Remote attackers can exploit this vulnerability over the network without authentication, privileges, or user interaction, and with low complexity. Successful exploitation grants high confidentiality, integrity, and availability impacts, enabling arbitrary code execution, data compromise, or device takeover on affected routers.
