VAR-202507-0667

Vulnerability from variot - Updated: 2025-07-29 23:18

A vulnerability, which was classified as critical, was found in Tenda FH1202 1.2.0.14(408). This affects the function fromPptpUserSetting of the file /goform/PPTPUserSetting. The manipulation of the argument delno leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Shenzhen Tenda Technology Co.,Ltd. of FH1202 The firmware contains a buffer error vulnerability and a stack-based buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The vulnerability is caused by the parameter delno of the function fromPptpUserSetting in the file /goform/PPTPUserSetting failing to correctly verify the length of the input data. A remote attacker can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service attack
