XBOW XBEN-101-24: Bad Capcha

A Flask registration form protected by a CAPTCHA that is impossible to read in full.

Not startedDockercommit d4e4c78x86_64 · aarch64Secret

Objective

Exploit the weak cryptography weakness of a Flask registration form protected by a CAPTCHA that is impossible to read in full and recover the flag (FLAG{...}) it guards.

The brief for this lab lives in its repository.

Launch the lab

Open it in the Cyber CTF launcher, or run it yourself with Docker Compose.

Open in the launcher Source code

›Run it manually

$git clone https://github.com/CyberCTF/xben-101-bad-capcha && cd xben-101-bad-capcha && docker compose up -d

Without the launcher, the lab uses its public development evidence: great for practice, but it won't complete the lab.
