Vulnerability from variot - Updated: 2025-11-19 23:27

A security flaw has been discovered in Tenda AC18 15.03.05.19(6318). Affected by this issue is some unknown functionality of the file /goform/fast_setting_pppoe_set. Performing manipulation of the argument Username results in stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been released to the public and may be exploited. The Tenda AC18 is a dual-band wireless router launched by Shenzhen Jixiang Tengda Technology Co., Ltd. in July 2016, primarily for villa and large-sized home users.

The Tenda AC18 suffers from a stack buffer overflow vulnerability. This vulnerability stems from a failure to properly validate the length of the input data in the parameter Username in the file /goform/fast_setting_pppoe_set. An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
