device is 5.4.x prior to 5.4.3. It is, therefore, affected by a
cross-site redirection vulnerability in its web-based user interface
due to improper validation of input before returning it to users. An
unauthenticated, remote attacker can exploit this, via a specially

of the attacker's choosing.");
