CVE-2024-37152
Published: 06 June 2024
Summary
CVE-2024-37152 is a medium-severity Improper Authentication (CWE-287) vulnerability in Argoproj Argo Cd. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 0.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Argo CD, a declarative GitOps continuous delivery tool for Kubernetes, contains an authentication bypass affecting the /api/v1/settings endpoint. The flaw permits unauthenticated access to sensitive configuration data; all fields remain masked except for passwordPattern, which is disclosed in plaintext. The issue is tracked under CWE-287 and CWE-306 and carries a CVSS 3.1 score of 5.3 reflecting network-reachable exposure without credentials.
An attacker with network access to an Argo CD instance can retrieve the exposed passwordPattern value and potentially leverage it to infer or validate password policies used by the deployment. Because the endpoint requires no authentication, the attack can be performed remotely by any party able to reach the API, resulting in limited confidentiality impact without affecting integrity or availability.
The vulnerability is resolved in Argo CD versions 2.11.3, 2.10.12, and 2.9.17. Official advisories and the accompanying commits on GitHub recommend immediate upgrade to one of the patched releases; no workarounds are documented in the referenced security notices. The EPSS score has remained at 0.8020 with no material increase observed after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Session content review can reveal authentication bypasses or failures in session establishment.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
Documented IA policy and procedures require proper authentication mechanisms to be defined and followed, reducing improper authentication.
Requires adaptive authentication under specific conditions, directly strengthening authentication mechanisms against improper or insufficient authentication.
Identity providers centralize and enforce authentication mechanisms, reducing improper authentication.
Requires unique identification and authentication of organizational users, directly preventing improper authentication.
Enforces unique device identification and authentication before any connection is established, directly mitigating improper authentication weaknesses.
Directly requires implementation of compliant authentication mechanisms to cryptographic modules, preventing improper authentication.
