VAR-202507-0504

Vulnerability from variot - Updated: 2025-07-30 23:18

A vulnerability, which was classified as critical, was found in Tenda O3V2 1.0.0.12(3880). Affected is the function fromSysToolTime of the file /goform/setSysTimeInfo of the component httpd. The manipulation of the argument Time leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. Shenzhen Tenda Technology Co.,Ltd. of o3 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. This vulnerability stems from the failure to properly validate the length of the input data in the "time" parameter in the file /goform/setSysTimeInfo. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
