Overview
CVE-2025-8060 is a critical vulnerability that has been discovered in Tenda AC23 version 16.03.07.52, a popular networking device. This vulnerability, if exploited, can potentially compromise the system and lead to data leakage. It is particularly concerning given its severity and the fact that the exploit has been made publicly available. This could potentially make it a target for malicious cyber actors looking to exploit unprotected systems.
The vulnerability occurs in the function sub_46C940 of the file /goform/setMacFilterCfg of the httpd component. The manipulation of the deviceList argument leads to a stack-based buffer overflow, which can be launched remotely. Therefore, it is crucial that system administrators and security professionals are aware of this vulnerability and take appropriate action to mitigate the risk.

How the Exploit Works
The exploit works by manipulating the deviceList argument in the httpd component’s sub_46C940 function. By inputting a specially crafted payload, an attacker can cause a stack-based buffer overflow. This condition can allow the attacker to execute arbitrary code or cause a denial of service. Given that the attack can be launched remotely and requires no user interaction or privileges, it poses a significant risk.
Conceptual Example Code
Below is a
conceptual
example of how the vulnerability might be exploited. This is a hypothetical HTTP request that may be used to trigger the vulnerability:
POST /goform/setMacFilterCfg HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "deviceList": "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"}This is a simple buffer overflow attack where the deviceList argument is filled with an excessive number of ‘A’ characters. Please note that this is purely for illustrative purposes and not a literal exploit code.
Mitigation
Users are advised to apply the vendor patch as soon as it’s available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and prevent the exploitation of this vulnerability.
