Name of the Vulnerable Software and Affected Versions TOTOLINK EX1200L version 9.3.5u.6146 B20201023

Description A critical issue affects the UploadCustomModule function of the /cgi-bin/cstecgi.cgi file, caused by a buffer overflow when handling the File parameter. This allows a remote attacker to impact the confidentiality, integrity, and availability of protected information by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint.

Recommendations For version 9.3.5u.6146 B20201023, as a temporary workaround, consider disabling the UploadCustomModule function until a patch is available. Restrict access to the /cgi-bin/cstecgi.cgi endpoint to minimize the risk of exploitation. Avoid using the File parameter 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.
