**Name of the Vulnerable Software and Affected Versions**
TOTOLINK EX1200T version 4.1.2cu.5232 B20210713
**Description**
A critical vulnerability has been found in the TOTOLINK EX1200T router's embedded boa server, specifically in the /boafrm/formSysCmd file. This issue is related to a buffer overflow in memory, which can be exploited by sending a specially crafted POST request. The manipulation of the `submit-url` argument leads to this buffer overflow. The attack can be launched remotely, potentially affecting the confidentiality, integrity, and availability of protected information.
**Recommendations**
For TOTOLINK EX1200T version 4.1.2cu.5232 B20210713, as a temporary workaround, consider disabling the /boafrm/formSysCmd endpoint until a patch is available. Restrict access to the HTTP POST Request Handler to minimize the risk of exploitation. Avoid using the `submit-url` 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.
