Renegade BBS Directory Traversal Tshirt



Renegade was a “freeware” BBS (bulletin board system) written for MS-DOS based PC-compatible computers in the early-to-mid 1990s. Renegade was originally written by Cott Lang in the Pascal programming language.

A BBS allows one to host a “pre internet” community on your own computer, which acts as a dialup “Server” that people can connect to to share messages, files and play games called “Doors”.

This t-shirt highlights a publicized and well-known vulnerability in one of the earlier versions of the Renegade BBS software. In the file area of Renegade, there is a function to allow you to search the file archive database in order to find a particular file or archive that you are looking for. In the search field, the vulnerability allowed you to traverse the folder structure that renegade ran under and allowed you to access the coveted “renegade.dat” file. Renegade.dat was the data file that the BBS used to store all user account data, including the main administrator or “SysOp”. Downloading this file allowed a user to “own” an entire BBS and circumvent any access controls.

This t-shirt is everything you’ve dreamed of and more. It feels soft and lightweight, with the right amount of stretch. It’s comfortable and flattering for both men and women.
