Tenda AC10 v4.0 Firmware | v16.03.10.20
How the Exploit Works
The vulnerability resides in the get_parentControl_list_Info function of the Tenda AC10 v4.0 firmware v16.03.10.20. An attacker can exploit this vulnerability by sending a specially crafted packet to the targeted system. This oversized packet would trigger a stack overflow in the function, causing the system to crash or execute arbitrary code, leading to potential system compromise or data leakage.
Conceptual Example Code
Given the nature of this vulnerability, a potential exploitation could occur in the form of a HTTP request as illustrated below:
POST /get_parentControl_list_Info HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "[INSERT OVERFLOW PAYLOAD HERE]" }
The “malicious_payload” would contain an oversized data string designed to trigger the stack overflow in the get_parentControl_list_Info function.
Mitigation
Users and network administrators are advised to apply the vendor-supplied patch to address this vulnerability. In the absence of a patch, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation, configured to detect and block attempts to exploit this vulnerability.
