A vulnerability was identified in Trendnet TEW-635BRM up to 1.00.03. This affects the function start_httpd of the file /sbin/rc of the component Web Service. Such manipulation of the argument device_name leads to stack-based buffer overflow. The attack can be executed remotely. The exploit is publicly available and might be used. The vendor explains: "We are unable to confirm if the vulnerability exists. This item has been EOL since 2011. We will make an official announcement of possible vulnerabilities, and recommend users to switch devices." This vulnerability only affects products that are no longer supported by the maintainer.
