TITLE

Tenda AX-1803 sub_4F55C function stack buffer overflow vulnerability

Trust: 0.6

sources: CNVD: CNVD-2025-28841

DESCRIPTION

Tenda AX-1803 v1.0.0.1 was discovered to contain a stack overflow via the wanMTU parameter in the sub_4F55C function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request. The Tenda AX-1803 is a dual-band gigabit WiFi 6 wireless router from Tenda, supporting both 2.4GHz and 5GHz bands with a maximum transmission rate of 1774Mbps, suitable for home or small office environments. This vulnerability stems from the fact that the wanMTU parameter in the sub_4F55C function fails to properly validate the length of the input data. An attacker could exploit this vulnerability to cause a denial-of-service attack
