DS Station's web browser uses NetFront 3.3. This browser version has a stack smash bug in a function writing the URL from a tag field's value to the stack. This bug is present in at least one function, it's unknown if other functions have this bug as well.

It is currently unknown if Nintendo Zone uses a newer NetFront version with this bug fixed. A Nintendo Zone exploit couldn't be easily used by everyone, as Linux and a compatible hostapd wireless NIC is required. An SSID, and the WEP key generated from the SSID, from a real Nintendo Zone/DS Station AP is required.

At real Nintendo Zone APs, a laptop running Linux with a wireless NIC supporting monitor mode would be needed.

This exploit would be meant more for reverse engineers.

A DS Station exploit has been written by Yellows8. This DS Station exploit can't be adapted to Nintendo Zone until an Nintendo Zone AP capture and Nintendo Zone binary are obtained. A volunteer to capture Nintendo Zone AP traffic and the WMB binary was found a long while ago, but it is unknown when he'll capture. Perhaps sometime this month(March), but it's unknown. This exploit can only be used with html that is transferred over http. The html for the index main and sub screens is transferred over https. However, the html for the main screen for the pages after the index,(main server and third-party companies websites) is transferred with http. The sub screen html is transferred with https, with the main server. Sub screen html with third-party companies is transferred with http. Strangely, the back link from the menu after the index page for the main server, the main screen html URL uses http, rather than https.

A means of bootstrapping homebrew is being worked on. Bootstrapping a .nds embedded in the exploit has been done somewhat successfully, but Arm7 code doesn't work 100%. Bootstrapping the Arm7 works fine when done with the embedded .nds. There seems to be zero issues with homebrew bootstrapped from a loader embedded in the exploit. When attempting to use touch screen in the embedded .nds, the Arm7 code doesn't work at all for touch screen. Most of the time, Arm7 Wifi doesn't work, it only worked once. NetFront limits the size of html files that can be downloaded. The max size of a LZSS compressed .nds embedded in the exploit is roughly 200KB.
