Name of the Vulnerable Software and Affected Versions D-Link DIR-823-Pro version 1.0.2

Description The issue is related to the implementation of the SetNTPserverSeting() function in the D-Link DIR-823-Pro wireless router's firmware, which fails to properly sanitize data at the management level. This allows a remote attacker to execute arbitrary commands using the system time timezone parameter.

Recommendations For D-Link DIR-823-Pro version 1.0.2, consider disabling the SetNTPserverSeting() function until a patch is available to prevent exploitation via the system time timezone parameter. Restrict access to the vulnerable function to minimize the risk of arbitrary command execution. Avoid using the system time timezone parameter in the affected function until the issue is resolved.
