This challenge presents a scenario where we are given admin access to a CTFd instance. A bot (the "scraper") runs inside the infrastructure and automatically scrapes the CTFd instance every 30 seconds using JohnHammond/ctfd-download, a Python tool for downloading CTFd challenge data. The challenge involves exploiting a path traversal vulnerability combined with a URL fragment injection in an older version of this scraper tool to achieve arbitrary file write on the scraper's filesystem, ultimately leading to Python module hijacking and remote code execution on the scraper container, which holds the flag at…

Aros-25 is a reverse engineering and exploitation challenge featuring a custom virtual machine (VM) implemented as an ARM32 binary. The challenge presents competitors with a stripped, obfuscated ARM executable that implements a simple bytecode interpreter. Players must reverse engineer the VM's instruction set, understand its memory model, identify security constraints, and ultimately craft a payload that reads the flag file from the remote server.
