Not exactly, read first link carefully:

Tested on D-Link DSL-G624T
Version: Firmware Version : V3.00B01T01.YA-C.20060616

Discovered by:

Jose Ramon Palanco: jose.palanco(at)eazel(dot).es

These firmware date is even newer than yours :)

Jose mentions both directory traversal and 3 examples of crossite
scripting. Crossite scripting examples are different from yours though
and require POST request. Your CSS is easier to exploit.

In fact, at least Russian D-Link support is very responsive to any bug
report, but it seems like only way to get a response is to post a
problem on their forum.
