Voilà (Baby)

intro misc FCSC 2025 solved on

Description

Alice loves listening to music. Unfortunately, she misconfigured her firewall and accidentally exposed her music collection on the Internet. Alice organizes her personal collection in an unconventional way: instead of sorting by genre, album, or artist, she renames her music files based on her imagination.

To begin, connect to her music collection and find the hidden flag in the metadata.

Alice’s music collection is accessible at localhost:4000.

This challenge is also available in a more difficult version: Voilà.
