Summary

CVE-2025-8060 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Ac23 Firmware. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 21.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).

Deeper analysis

CVE-2025-8060 is a stack-based buffer overflow vulnerability affecting the Tenda AC23 wireless router running firmware version 16.03.07.52. It resides in the sub_46C940 function of the /goform/setMacFilterCfg endpoint inside the httpd component and is triggered by unsanitized input to the deviceList argument. The issue is tracked under CWE-119 and CWE-121 and carries a CVSS 4.0 score of 7.4.

An authenticated remote attacker can send a crafted HTTP request to the affected endpoint, causing memory corruption that may result in arbitrary code execution or a crash of the web server process. Public proof-of-concept code has already been released, confirming that the attack requires no user interaction beyond valid credentials and can be launched over the network.

The listed references point to a detailed technical write-up and VulDB entries but contain no vendor-supplied patch or mitigation guidance at the time of publication. The associated EPSS score remains flat at 0.0110 with no observed rise after disclosure.

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?

Stack-based buffer overflow in the httpd web interface (/goform/setMacFilterCfg) allows remote unauthenticated attackers to achieve arbitrary code execution by manipulating the deviceList parameter, enabling exploitation of a public-facing application.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly remediates the stack-based buffer overflow vulnerability by applying vendor firmware patches or updates to the affected Tenda AC23 httpd component.

prevent

Validates and sanitizes the deviceList argument in the /goform/setMacFilterCfg endpoint to prevent the buffer overflow triggered by malformed input.

prevent

Implements memory protections such as stack canaries, ASLR, and DEP to block arbitrary code execution from the stack-based buffer overflow even if triggered.
