Security Advisory: XSS WUI Issue

TL;DR - Update your Vigor 3900/2960 firmware to version 1.4.3 in order to improve XSS Web UI Protection.

In March 2019, we became aware of a possible exploit of the Vigor 2960/3900.  It was identified during testing and reported to us*. It is somewhat limited in scope and likelyhood and requires some fairly specific factors, however as it is still possible, we have corrected the code and issued this advisory.  The exploit does not allow access to router settings, Internet traffic or your LAN.  The only advice necessary is to upgrade your firmware to version 1.4.3 - and always keep it up to date.

In order to protect users, no other information about the issue is being provided at present.

This issue is for Vigor 2960/3900 only and no other DrayTek products.

Firmware downloads are available from here (For UK/IE Region only).
