The vulnerability was found by Check Point researchers and existed within the UPnP (Universal Plug and Play) service of the router. Attackers could exploit it by crafting a malicious SOAP XML message and sending it to the router. When the device processed this request, it would unknowingly execute whatever commands the attacker had embedded. This could allow an attacker to install malware, launch DDoS attacks, or take full control of the device.

A "fixed" status is achieved only when the software version is verified to be post-patch and the device is configured to deny WAN-side access to the UPnP service. Network administrators must transition from relying on endpoint patching to network segmentation, ensuring that even if a device is unpatched, it cannot be reached from the public internet.
