The following issues were identified:

It is reported that an attacker can bypass URI filters of the device.

The URI filter log viewer is reported prone to a cross-site scripting vulnerability.

The research report specified that FVS318 devices with firmware 2.4 are vulnerable to these issues. FVS318 and FVS318v2 are shipped with firmware 2.4, however, it is possible that FVS318v3 and other firmware versions are affected as well. This BID will be updated when more information about affected packages is available.
