Vulnerability from variot - Updated: 2025-08-09 23:18

TOTOLINK LR350 V9.3.5u.6698_B20230810 was discovered to contain a stack overflow via the password parameter in the function loginAuth. TOTOLINK of lr350 Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK LR350 is a 4G LTE router released by China's TOTOLINK Electronics. It converts 4G signals into wired signals and is suitable for home and office use.

The TOTOLINK LR350 suffers from a buffer overflow vulnerability. This vulnerability stems from the failure to properly validate the length of the input data in the password parameter of the loginAuth function. An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
