OWASP SKF Pickle Deserialization

A Flask page that 'syncs' user preferences: it takes a hex-encoded Python pickle from the form and loads it with pickle.load.

Not startedDockercommit c2cd9fcx86_64 · aarch64Secret

Objective

Send a crafted pickle that runs a command on the server when it is deserialized (insecure deserialization).

The brief for this lab lives in its repository.

Submit evidenceSecret

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/skf-des-pickle && cd skf-des-pickle && docker compose up -d

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