TITLE

TOTOLINK of lr1200gb Command injection vulnerability in firmware

Trust: 0.8

sources: JVNDB: JVNDB-2025-019689

DESCRIPTION

An unauthenticated command injection vulnerability exists in the ToToLink LR1200GB Router firmware V9.1.0u.6619_B20230130 within the cstecgi.cgi binary (sub_41EC68 function). The binary reads the "imei" parameter from a web request and verifies only that it is 15 characters long. The parameter is then directly inserted into a system command using sprintf() and executed with system(). Maliciously crafted IMEI input can execute arbitrary commands on the router without authentication. The TOTOLINK LR1200GB is a dual-band 4G LTE router launched by TOTOLINK, a Chinese electronics company, supporting both 2.4GHz and 5GHz dual-band networks. This vulnerability stems from the cstecgi.cgi binary file failing to properly filter special characters and commands used in command construction. Detailed vulnerability information is currently unavailable
