Produktbeschreibung: Vault ist ein identitätsbasiertes System zur Verwaltung von Geheimnissen und Verschlüsselung.

Angriff: Ein lokaler Angreifer kann eine Schwachstelle in Hashicorp Vault ausnutzen, um kryptografische Sicherheitsvorkehrungen zu umgehen.

Betroffene Betriebssysteme: - UNIX - Linux - Sonstiges

CVE-2023-2197

Es besteht eine Schwachstelle in Hashicorp Vault in Konfigurationen, die ein Hardware-Sicherheitsmodul (HSM) konfiguriert haben und CBC-basierte Verschlüsselung verwenden (Standard CKM_AES_CBC_PAD oder CKM_AES_CBC). HSM-Nachrichten sind in diesem Fall nicht ordnungsgemäß mit HMAC geschützt. Ein Angreifer mit bestimmten Rechten kann dies ausnutzen, um den Chiffretext abzufangen oder zu ändern, um den Root-Schlüssel von Vault abzuleiten.

Title

Vault Enterprise Vulnerable to Padding Oracle Attacks When Using a CBC-based Encryption Mechanism with a HSM

Summary

HashiCorp Vault Enterprise 1.13.0 up to 1.13.1 is vulnerable to a padding oracle attack when using an HSM in conjunction with the CKM_AES_CBC_PAD or CKM_AES_CBC encryption mechanisms. An attacker with privileges to modify storage and restart Vault may be able to intercept or modify cipher text in order to derive Vault’s root key. Fixed in 1.13.2
