CVE-2022-40186
Description
A flaw was found in HashiCorp Vault and Vault Enterprise, where they could allow a locally authenticated attacker to gain unauthorized access to the system, caused by a flaw in the alias naming schema implementation for mount accessors with shared alias names in the Identity Engine. By conducting a specially-crafted operation, an attacker can overwrite metadata to the wrong alias, gaining unauthorized access to key/value paths using the metadata in Vault.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
