CVE-2024-21652

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.8.13, 2.9.9, and 2.10.4, an attacker can exploit a chain of vulnerabilities, including a Denial of Service (DoS) flaw and in-memory data storage weakness, to effectively bypass the applications brute force login protection. This is a critical security vulnerability that allows attackers to bypass the brute force login protection mechanism. Not only can they crash the service affecting all users, but they can also make unlimited login attempts, increasing the risk of account compromise. Versions 2.8.13, 2.9.9, and 2.10.4 contain a patch for this issue.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

Affected Software

Potential Mitigations

• Common protection mechanisms include:

• Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].

• Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
