**Name of the Vulnerable Software and Affected Versions** Totolink LR1200GB versions 9.1.0u.6619 B20230130 through 9.3.5u.6698 B20230810 **Description** A critical vulnerability has been found in the Web Interface component of Totolink LR1200GB, specifically in the `loginAuth` function of the file `/cgi-bin/cstecgi.cgi`. The manipulation of the `http host` argument leads to a stack-based buffer overflow, allowing a remote attacker to launch an attack. The exploit has been disclosed to the public and may be used. **Recommendations** For Totolink LR1200GB versions 9.1.0u.6619 B20230130 through 9.3.5u.6698 B20230810, consider disabling the `loginAuth` function of the `/cgi-bin/cstecgi.cgi` file as a temporary workaround until a patch is available. Restrict access to the vulnerable Web Interface component to minimize the risk of exploitation. Avoid using the `http host` argument in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
