Incorrect Authorization
CVE-2023-23947
Summary
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. The packages github.com/argoproj/argo-cd and github.com/argoproj/argo-cd/v2 versions starting with 2.3.x prior to 2.3.17, 2.4.x prior to 2.4.23, 2.5.x prior to 2.5.11, and 2.6.x prior to 2.6.2 are vulnerable to an improper authorization bug which allows users who have the ability to update at least one cluster secret to update any cluster secret. The attacker could use this access to escalate privileges (potentially controlling Kubernetes resources) or to break Argo CD functionality (by preventing connections to external clusters). Two workarounds are available. Either modify the RBAC configuration to completely revoke all "clusters", "update", "access", or use the "destinations" and "clusterResourceWhitelist" fields to apply similar restrictions as the "namespaces" and "clusterResources" fields.

CWE-863 - Incorrect Authorization
Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
