CVE-2022-31034 : Exploit Details and Defense Strategies

Argo CD, a declarative GitOps continuous delivery tool for Kubernetes, has been found to have an insecure entropy vulnerability that affects versions starting from v0.11.0. This vulnerability allows attackers to exploit SSO login flows, potentially gaining admin access to Argo CD.

Understanding CVE-2022-31034

This section delves into the details of the CVE-2022-31034 vulnerability in Argo CD.

What is CVE-2022-31034?

Argo CD versions prior to v2.4.1, v2.3.5, v2.2.10, and v2.1.16 are susceptible to attacks through insufficiently random values in parameters during Oauth2/OIDC login flows. These vulnerabilities stem from using predictable seed values in a non-secure random number generator, reducing the randomness required for secure parameters.

The Impact of CVE-2022-31034

The CVE-2022-31034 vulnerability in Argo CD has a high severity rating with a CVSS base score of 8.3. The attack complexity is high, requiring no user privileges, and can lead to significant impacts on confidentiality, integrity, and availability. It can potentially grant attackers admin access to Argo CD.
