VAR-202401-0372
Vulnerability from variot - Updated: 2025-08-10 23:27A vulnerability was found in Totolink LR1200GB 9.1.0u.6619_B20230130. It has been rated as critical. This issue affects the function setLanguageCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument lang leads to stack-based buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-250793 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of lr1200gb A stack-based buffer overflow vulnerability exists in the firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK LR1200GB is a wireless dual-band 4G LTE router released by China's TOTOLINK Electronics. It supports both 2.4GHz and 5GHz bands.
The TOTOLINK LR1200GB suffers from a buffer overflow vulnerability. This vulnerability stems from the setLanguageCfg function in the /cgi-bin/cstecgi.cgi file failing to properly validate the length of the input data in the lang parameter. An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
