Name of the Vulnerable Software and Affected Versions D-Link DIR-513 version 1.10

Description The D-Link DIR-513 version 1.10 device has a flaw where it doesn't properly check the FILECODE parameter when handling POST requests to the /goform/formLogin endpoint. This allows for a path traversal issue when the system processes requests through the /goform/getAuthCode function.

Recommendations Update to a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the /goform/formLogin endpoint to minimize the risk of exploitation.
