A vulnerability was found in Argo CD up to 2.1.15/2.2.9/2.3.4/2.4.0 and classified as problematic. This issue affects an unknown code of the component SSO Login. The manipulation of the argument random with an unknown input leads to a random values vulnerability. Using CWE to declare the problem leads to CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v0.11.0 are vulnerable to a variety of attacks when an SSO login is initiated from the Argo CD CLI or UI. The vulnerabilities are due to the use of insufficiently random values in parameters in Oauth2/OIDC login flows. In each case, using a relatively-predictable (time-based) seed in a non-cryptographically-secure pseudo-random number generator made the parameter less random than required by the relevant spec or by general best practices. In some cases, using too short a value made the entropy even less sufficient. The attacks on login flows which are meant to be mitigated by these parameters are difficult to accomplish but can have a high impact potentially granting an attacker admin access to Argo CD. Patches for this vulnerability has been released in the following Argo CD versions: v2.4.1, v2.3.5, v2.2.10 and v2.1.16. There are no known workarounds for this vulnerability.

The weakness was shared 06/27/2022 as GHSA-2m7h-86qq-fp4v. The advisory is shared at github.com. The identification of this vulnerability is CVE-2022-31034 since 05/18/2022. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

Upgrading to version 2.1.16, 2.2.10, 2.3.5 or 2.4.1 eliminates this vulnerability. Applying the patch 17f7f4f462bdb233e1b9b36f67099f41052d8cb0 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
