CERTFR-2020-ALE-012

Vulnerability from certfr_alerte - Published: - Updated:

De multiples vulnérabilités ont été découvertes dans les deux versions 2019 et 3000 de la solution SaltStack. Elles permettent à un attaquant de provoquer une exécution de code arbitraire et un contournement de la politique de sécurité.

Plusieurs incidents de sécurité ont été relayés en source ouverte suite à des attaques ciblées.

Le CERT-FR recommande l’application de la mise à jour dans les plus brefs délais selon les recommandations de l'éditeur.

Enfin, le CERT-FR recommande également d'appliquer les bonnes pratiques de cloisonnement des composants d'administration [1] et de renouveler les secrets d'authentification utilisés par la solution SaltStack. Il est enfin fortement recommandé de procéder à une vérification de la sécurité du Système d’Information afin de détecter une attaque éventuelle.

Solution

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

CVE-2020-11651 (GCVE-0-2020-11651)

Vulnerability from cvelistv5 – Published: 2020-04-30 16:58 – Updated: 2025-10-21 23:35

Summary

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.

Severity ?

9.8 (Critical)
