CVE-2026-36786 Details
Description
Shenzhen Tenda Technology Co., Ltd Tenda FH451 V1.0.0.9 was discovered to contain a stack overflow in the list1 parameter of the fromDhcpListClient function. This vulnerability allows 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 FH451 router, specifically in version 1.0.0.9. The issue arises in the 'fromDhcpListClient' function, which is part of the device's CGI handler. This vulnerability allows attackers to cause a denial-of-service condition by sending a crafted HTTP request that exploits the 'list1' parameter. The overflow occurs because the parameter is not properly validated before being copied into a buffer, leading to a process crash or instability on the device.
