Technical Analysis

This appliance is targetted towards small to medium enterprise which means it more valuable to an attacker than attacks against home user equipment.

If compromised access to this device could be used to perform network-level compromise via DNS attacks or reveal sensitive information about the network.

It requires local network access in order to exploit the vulnerability. This device lists “Guest access control” as one of its features so depending on its configuration Local access my be available.

Devices like APs and embedded devices are often overlooked when applying security updates and patches.

At the time of analysis, there is no firmware update available to remediate the vulnerability although POC code does not yet appear to be publicly available.

Despite the absence of available POC code it is trivial to download the firmware and extract the files system. A determined attacker could then identify the exploit manually.
