CVE-2026-36789 Details
Description
Shenzhen Tenda Technology Co., Ltd Tenda AC1206 v15.03.06.23 was discovered to contain multiple stack overflows in the fromGstDhcpSetSer function via the username and password parameters. These vulnerabilities allow attackers to cause a Denial of Service (DoS) via a crafted HTTP request.
A stack-based buffer overflow vulnerability has been identified in the Tenda AC1206 router, specifically in version 15.03.06.23. The issue arises in the 'fromGstDhcpSetSer' CGI handler, where user-controlled 'username' and 'password' parameters are processed without proper length validation or sanitization. This vulnerability can be exploited by sending a crafted HTTP request to the 'fromGstDhcpSetSer' endpoint, causing a denial-of-service condition by crashing or rebooting the device. Additionally, this vulnerability could potentially be exploited for remote code execution.
