CVE-2024-8185
Description
A flaw was found in HashiCorp Vault. Clusters using Vault’s Integrated Storage backend are vulnerable to a denial of service (DoS) attack through memory exhaustion through a Raft cluster join API endpoint. This flaw allows an attacker to send a large volume of requests to the endpoint, which may cause Vault to consume excessive system memory resources, potentially leading to a crash of the underlying system and the Vault process itself.
Statement
This vulnerability is rated as important severity because it allows attackers to exploit the Raft cluster join API in HashiCorp Vault, leading to denial of service through memory exhaustion. The ability to send a high volume of requests can overwhelm system resources, potentially crashing both the Vault process and the underlying system
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
