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.
DSiWare savedata is extracted and modified with these tools: https://github.com/neimod/dsi
DSiWare with incomplete analysis
| Name | Input type(s) | Status | Description |
|---|---|---|---|
| Bookworm | High-scores and word list | None | Has ASCII null-terminated high-score list names and null-terminated word list strings. |
| Escapee Go | None | None | Has high-scores without names, scores are ASCII null-terminated strings. |
| 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. But all the functions that copy to these lists seem to use strncpy, and it's unknown what code copies from savedata records to these lists. |
| Legends of Exidia | Player name | None | Has ASCII player name in one file, and UCS-2 player name in a profile file. |
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. |
| Dark Void Zero | High-Scores | 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. |
| Dracula | No manual input | Savedata contains ASCII high-scores from DSi username, and ASCII perks/powerups. High-scores doesn't have string bugs. |
| Paul's Shooting Adventure | High-Scores | Records are entered when you complete the game, names are ASCII strings null-terminated. Not exploitable. |
