DSiWare VulnList

This lists DSiWare that might have vulnerabilities, like strcpy or sprintf from savedata. If you know of DSiWare that has English-only string(high-scores, player name, high-scores that use username from system settings, etc) input, mention it on IRC EFNet #dsidev. Or contact yellowstar 6 at gmail dot com. Before you contact anyone about your dsiware, please make sure your dsiware is _not_ listed on this page anywhere.

DSiWare savedata is extracted and modified with these tools: https://github.com/neimod/dsi

For these lists status "None" means code reversing engineering for the DSiWare wasn't started. Status "Started" means code reversing engineering for that DSiWare was started. Status "Done" means code reverse engineering was finished.

DSiWare that can be crashed

Name	Input type(s)	Status	Description
Dark Void Zero	High-Scores	Done	No limit on length of drawn record names, no vuln with high-scores. The level var from savedata doesn't have any bounds check, this is used with array indexes. This is not exploitable since the array structs only contain char* strings and other fields, and that var is used with level class init. Level class init fail is most likely the cause of the crash which isn't exploitable, level paths are determined by if statements and the level object is used uninitialized when the level var is out-of-bounds.
Frogger Returns	High-scores	Started	Has ASCII null-terminated high-scores. Manged to crash this game. The high-score draw function uses strcpy to copy the records' name to a static buffer, it's unknown if this is exploitable.
Legends of Exidia	Player name	None	Has ASCII player name in one file, and UCS-2 player name in a profile file. This game was crashed by modifying strings in the profile savedata file.
Sudoku	Player name	None	Has ASCII player name for each of the 3 save slots. Game was crashed with an excessively long player name.

DSiWare with incomplete analysis

Name	Input type(s)	Status	Description
Escapee Go	None	Started	Has high-scores without names, scores are ASCII null-terminated strings. Managed to semi-crash this, but system reset still worked so this probably isn't exploitable.

DSiWare with finished analysis

Name	Input type(s)	Description
Arcade Hoops Basketball	High-Scores, names via settings	Has ASCII high-scores with null terminated strings, no string bugs.
Bookworm	High-scores and word list	Has ASCII null-terminated high-score list names and null-terminated word list strings. ( No crash, just nice very high scores, and very long words displayed. )
