Summary

Tookie: Arbitrary file write via path traversal in -u username / -U userfile output filename

Details

Tookie is a advanced OSINT information gathering tool. Prior to 4.1fix, modules/modules.py's writetxt, writecsv, writejson, and (commented-but-shipping) scanfile helpers open their output as open(f"{user}.<ext>"), where user comes unsanitized from the -u CLI flag or any line of a -U usernames file. A username that contains path-separator sequences (.., /, \, or an absolute path) causes tookie-osint to write the scan output to an arbitrary path the invoking user has write permission for. This vulnerability is fixed in 4.1fix.
