Background
Argo CD is an open-source continuous delivery tool for Kubernetes. It provides a web-based user interface for managing and deploying applications in Kubernetes clusters. The login screen is an essential component of Argo CD, where users authenticate themselves before accessing the system. However, when single sign-on (SSO) is enabled, a vulnerability exists that allows an attacker to spoof error messages on the login screen.
Vulnerability Detail
The vulnerability in Argo CD allows an attacker to manipulate the error messages displayed on the login screen when SSO is enabled. To exploit this vulnerability, the attacker needs to trick the victim into visiting a specially crafted URL containing the desired message. It's important to note that the spoofed message cannot contain active content like JavaScript or clickable links. The impact of this vulnerability is moderate, as it can potentially mislead users or create confusion during the authentication process.
