Summary

The vulnerability in D-Link DIR-818LW and DIR-822 routers arises from the improper handling of the RemotePort parameter in the /HNAP1/SetRouterSettings message. Without adequate regex validation, crafted XML messages can potentially allow attackers to inject shell metacharacters into the system configuration. This loophole can lead to significant security concerns, as it enables raw command execution through the device, putting users' networks at risk.
