Descriptions
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with 2.3.0 and prior to 2.3.6 and 2.4.5 is vulnerable to a cross-site scripting (XSS) bug which could allow an attacker to inject arbitrary JavaScript in the `/auth/callback` page in a victim's browser. This vulnerability only affects Argo CD instances which have single sign on (SSO) enabled. The exploit also assumes the attacker has 1) access to the API server's encryption key, 2) a method to add a cookie to the victim's browser, and 3) the ability to convince the victim to visit a malicious `/auth/callback` link. The vulnerability is classified as low severity because access to the API server's encryption key already grants a high level of access. Exploiting the XSS would allow the attacker to impersonate the victim, but would not grant any privileges which the attacker could not otherwise gain using the encryption key. A patch for this vulnerability has been released in the following Argo CD versions 2.4.5 and 2.3.6. There is currently no known workaround.
Argo CD es una herramienta declarativa de entrega continua GitOps para Kubernetes. Argo CD a partir de la versión 2.3.0 y anteriores a 2.3.6 y 2.4.5 es vulnerable a un bug de tipo cross-site scripting (XSS) que podría permitir a un atacante inyectar JavaScript arbitrario en la página "/auth/callback" en el navegador de la víctima. Esta vulnerabilidad sólo afecta a las instancias de CD de Argo que presentan activado el inicio de sesión único (SSO). La explotación también asume que el atacante presenta 1) acceso a la clave de encriptación del servidor API, 2) un método para añadir una cookie al navegador de la víctima, y 3) la capacidad de convencer a la víctima para que visite un enlace malicioso "/auth/callback". La vulnerabilidad es clasificada como de baja gravedad porque el acceso a la clave de cifrado del servidor de la API ya concede un alto nivel de acceso. La explotación de tipo XSS permitiría al atacante hacerse pasar por la víctima, pero no otorgaría ningún privilegio que el atacante no pudiera conseguir de otro modo usando la clave de cifrado. Ha sido publicado un parche para esta vulnerabilidad en las versiones 2.4.5 y 2.3.6 del CD de Argo. Actualmente no es conocida ninguna mitigación
