CVE-2022-29164 : Exploit Details and Defense Strategies

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. This vulnerability allows an attacker to create a workflow that produces an HTML artifact containing a script that interacts with the Argo Server API, potentially leading to privilege escalation.

Understanding CVE-2022-29164

This CVE highlights a privilege escalation vulnerability in argo-workflows that can be exploited by an attacker to manipulate workflows and potentially access sensitive information.

What is CVE-2022-29164?

In affected versions of Argo Workflows, an attacker with insider access can create a malicious workflow containing a script that communicates with the Argo Server API. By tricking a victim into opening a crafted artifact link, the attacker can execute code and potentially read or modify the victim's workflows.

The Impact of CVE-2022-29164

The high severity vulnerability can result in unauthorized access to confidential data, manipulation of workflows, and potential disruption of services within Kubernetes environments.

Technical Details of CVE-2022-29164

This section outlines the specifics of the vulnerability, affected systems, and the exploitation mechanism.

Vulnerability Description

The flaw in argo-workflows allows attackers to exploit the Argo Server API, enabling them to leverage XHR calls within HTML artifacts to gain unauthorized access to workflows and execute malicious actions.
