critical Tenable Self-Hosted Container Security Plugin ID 418518

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. A critical vulnerability has
 been discovered in Argo CD starting with version 1.4.0 and prior to versions 2.1.15, 2.2.9, and 2.3.4
 which would allow unauthenticated users to impersonate as any Argo CD user or role, including the `admin`
 user, by sending a specifically crafted JSON Web Token (JWT) along with the request. In order for this
 vulnerability to be exploited, anonymous access to the Argo CD instance must have been enabled. In a
 default Argo CD installation, anonymous access is disabled. The vulnerability can be exploited to
 impersonate as any user or role, including the built-in `admin` account regardless of whether it is
 enabled or disabled. Also, the attacker does not need an account on the Argo CD instance in order to
 exploit this. If anonymous access to the instance is enabled, an attacker can escalate their privileges,
 effectively allowing them to gain the same privileges on the cluster as the Argo CD instance, which is
 cluster admin in a default installation. This will allow the attacker to create, manipulate and delete any
 resource on the cluster. They may also exfiltrate data by deploying malicious workloads with elevated
 privileges, thus bypassing any redaction of sensitive data otherwise enforced by the Argo CD API. A patch
 for this vulnerability has been released in Argo CD versions 2.3.4, 2.2.9, and 2.1.15. As a workaround,
 one may disable anonymous access, but upgrading to a patched version is preferable. (CVE-2022-29165)
