Here is the full write-up for that challenge. Top File Category: Web Exploitation Points: [Varies, usually ~30-50 pts] The Challenge Description: The challenge typically presents a simple website with a search bar or a file lookup interface. The prompt implies that there is a "top file" or a secret file that needs to be read. Hint (often implied): Can you see what's on top? Initial Analysis Upon opening the provided website URL, you are usually greeted with a minimalist interface, often mimicking a file retrieval system or a search engine for "top" items.
The server script (likely PHP, Python, or Node) is taking the file parameter and looking for a file with that name.
However, in the original challenge, the intended solution was often simpler. The "top" hint referred to the root directory / .
The goal is to break out of the intended directory (likely something like /var/www/html/files/ ) and access the root directory or the flag file. 1. Investigating the URL Parameter If the site has a URL structure like: https://website.tjctf.org/?file=hello.txt or https://website.tjctf.org/?page=about
(Note: Sometimes filters block ../ , requiring variations like ....// or URL encoding %2e%2e%2f ) .
We want to access the "top" file. In CTF context, "top" usually implies the root directory / , or specifically the file /flag.txt , /flag , or /home/flag.txt .
