Name of the Vulnerable Software and Affected Versions ToToLink LR1200GB Router firmware version 9.1.0u.6619 B20230130

Description An unauthenticated command injection issue exists in the ToToLink LR1200GB Router firmware. The cstecgi.cgi binary, specifically the sub 41EC68 function, is affected. The binary receives the imei parameter from a web request and only validates its length (15 characters). This parameter is then directly incorporated into a system command using sprintf() and executed with system(). A crafted imei input can allow execution of arbitrary commands on the router without authentication.

Recommendations Update to a newer version that contains a fix for this vulnerability.
