VAR-202401-0463

Vulnerability from variot - Updated: 2025-12-19 22:57

A vulnerability was found in Totolink LR1200GB 9.1.0u.6619_B20230130. It has been classified as critical. This affects the function setTracerouteCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument command 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. The associated identifier of this vulnerability is VDB-250791. 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 command parameter of the setTracerouteCfg 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
