Descriptions

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v1.0.0 are vulnerable to a cross-site scripting (XSS) bug allowing a malicious user to inject a `javascript:` link in the UI. When clicked by a victim user, the script will execute with the victim's permissions (up to and including admin). The script would be capable of doing anything which is possible in the UI or via the API, such as creating, modifying, and deleting Kubernetes resources. A patch 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 completely-safe workarounds besides upgrading.

Argo CD es una herramienta declarativa de entrega continua GitOps para Kubernetes. Todas las versiones de Argo CD a partir de la v1.0.0, son vulnerables a un bug de tipo cross-site scripting (XSS) que permite a un usuario malicioso inyectar un enlace "javascript:" en la Interfaz de Usuario. Cuando un usuario víctima haga clic en él, el script será ejecutado con los permisos de la víctima (hasta el de administrador). El script sería capaz de hacer cualquier cosa que sea posible en la Interfaz de Usuario o por medio de la API, como crear, modificar y eliminar recursos de Kubernetes. Ha sido publicado un parche para esta vulnerabilidad en las siguientes versiones del CD de Argo: v2.4.1, v2.3.5, v2.2.10 y v2.1.16. No se presentan mitigaciones completamente seguras aparte de la actualización

A Cross-site scripting (XSS) flaw was found in ArgoCD. This flaw allows a malicious actor to trigger a Cross-site scripting (XSS) vulnerability by storing a link point to a javascript code in ArgoCD UI. A successful attack depends on a user clicking the malicious link and triggering the function available in the UI without the user's knowledge. The actions done by the malicious code will run with the same victim's level of access, including administrative privileges, if the victim has this level of permission.
