**Name of the Vulnerable Software and Affected Versions**
D-Link DIR-816 A2 version 1.10 B05
**Description**

For D-Link DIR-816 A2 version 1.10 B05, consider restricting access to the /goform/form2WizardStep4 endpoint and avoid using the `wizardstep4 pskpwd` parameter until a patch is available. As a temporary workaround, disabling the vulnerable component may help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
