VAR-202401-0536
Vulnerability from variot - Updated: 2025-12-19 22:35A vulnerability, which was classified as critical, has been found in Totolink LR1200GB 9.1.0u.6619_B20230130. This issue affects the function setSmsCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument text 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 associated identifier of this vulnerability is VDB-250787. 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 dual-band 4G LTE wireless router manufactured by TOTOLINK, a Chinese company. It supports both 2.4GHz and 5GHz dual-band networks and is primarily used to provide mobile broadband connectivity and Wi-Fi coverage. This vulnerability stems from the fact that the text parameter of the setSmsCfg function in the /cgi-bin/cstecgi.cgi file fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code or cause a denial-of-service attack
