CVSS v3.1
Official Description
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
Technical Analysis
CVE-2023-2197 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
