CVE-2025-71021 Details
Description
Tenda AX-1806 v1.0.0.1 was discovered to contain a stack overflow in the serverName parameter of the sub_65A28 function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.
A stack overflow vulnerability has been identified in the Tenda AX-1806 router, specifically in version 1.0.0.1. The issue arises in the 'sub_65A28' function, where the 'serverName' parameter is processed. The vulnerability allows attackers to cause a denial-of-service by sending a crafted request that exploits the lack of bounds checking in the 'strcpy' function. This oversight enables the 'serverName' value to overflow a fixed-size stack buffer, corrupting adjacent memory and crashing the device.
