Lake Overflow

You found an old internal login tool used by Crystal Lake staff.
It seems to have a small buffer for your name... maybe you can convince it you're an admin?

Files
- chal - the binary you run

How to play
1. Download both files
2. Make chal executable: chmod +x chal
3. Run: ./chal
4. Send input at the prompt

Goal
Upgrade your access level to "admin" and read the secret company memo.

Hint
Look at the source code - buffer sizes and unsafe functions are important.
