Name of the Vulnerable Software and Affected Versions TOTOLink A7100RU version V7.4cu.2313 B20191024

Description The issue is related to the lack of input data sanitization in the staticGw function of the TOTOLink A7100RU router's firmware. This allows a remote attacker to exploit the vulnerability and execute arbitrary code. The vulnerability is specifically a command injection issue via the staticGw parameter at the "/setting/setWanIeCfg" API endpoint.

Recommendations For TOTOLink A7100RU version V7.4cu.2313 B20191024, as a temporary workaround, consider disabling the staticGw function until a patch is available. Restrict access to the "/setting/setWanIeCfg" API endpoint to minimize the risk of exploitation. Avoid using the staticGw 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.
