Summary

The vulnerability in the D-Link DIR-1935 1.03 router allows network-adjacent attackers to bypass authentication protocols and execute arbitrary code on the device. The issue arises from improper validation of user-supplied strings in the SetIPv4FirewallSettings requests within the web management portal.
