Docker : falsification de requêtes côté serveur (SSRF)

1. Vérifier si vous êtes concerné

   Comparer la version installée aux versions corrigées ci-dessous.

   docker version
   containerd --version
   runc --version

2. Corriger

   Versions corrigées : voir l'avis de l'éditeur (lien dans les sources).

   Mettre à jour Docker Engine, containerd et runc, puis redémarrer le démon et les conteneurs.

   sudo apt update && sudo apt install --only-upgrade docker-ce docker-ce-cli containerd.io

3. En attendant le correctif

   Ne pas lancer d'images non fiables ; éviter les conteneurs privilégiés.

4. Contrôler

   docker version doit afficher les versions corrigées.

Commandes indicatives (Debian ou Ubuntu) : à adapter à chaque serveur, après sauvegarde.

Docker Model Runner (DMR) is software used to manage, run, and deploy AI models using Docker. Prior to version 1.1.25, Docker Model Runner contains an SSRF vulnerability in its OCI registry token exchange flow. When pulling a model, Model Runner follows the realm URL from the registry's WWW-Authenticate header without validating the scheme, hostname, or IP range. A malicious OCI registry can set the realm to an internal URL (e.g., http://127.0.0.1:3000/), causing Model Runner running on the host to make arbitrary GET requests to internal services and reflect the full response body back to the caller. Additionally, the token exchange mechanism can relay data from internal services back to the attacker-controlled registry via the Authorization: Bearer header. This issue has been patched in version 1.1.25. For Docker Desktop users, enabling Enhanced Container Isolation (ECI) blocks container access to Model Runner, preventing exploitation. However, if the Docker Model Runner is exposed to localhost over TCP in specific configurations, the vulnerability is still exploitable.
