Name of the Vulnerable Software and Affected Versions D-Link DIR-825 versions 2.10

Description The issue is related to the lack of input validation in the firmware of D-Link DIR-825 routers. This can be exploited by a remote attacker to execute arbitrary commands by sending a specially crafted POST request to the ntp sync.cgi endpoint through the ntp server parameter.

Recommendations For version 2.10, consider disabling the ntp sync.cgi endpoint or restricting access to it until a patch is available. Avoid using the ntp server parameter in the affected API endpoint until the issue is resolved.
