Descriptions

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 0.7.0 and prior to versions 2.1.15m 2.2.9, and 2.3.4 is vulnerable to a symlink following bug allowing a malicious user with repository write access to leak sensitive files from Argo CD's repo-server. A malicious Argo CD user with write access for a repository which is (or may be) used in a directory-type Application may commit a symlink which points to an out-of-bounds file. Sensitive files which could be leaked include manifest files from other Applications' source repositories (potentially decrypted files, if you are using a decryption plugin) or any JSON-formatted secrets which have been mounted as files on the repo-server. A patch for this vulnerability has been released in Argo CD versions 2.3.4, 2.2.9, and 2.1.15. Users of versions 2.3.0 or above who do not have any Jsonnet/directory-type Applications may disable the Jsonnet/directory config management tool as a workaround.

Argo CD es una herramienta declarativa de entrega continua GitOps para Kubernetes. Argo CD a partir de la versión 0.7.0 y versiones anteriores a 2.1.15m 2.2.9, y 2.3.4 es vulnerable a un fallo de seguimiento de symlink que permite a un usuario malicioso con acceso de escritura al repositorio filtrar archivos confidenciales desde el repo-servidor de Argo CD. Un usuario malicioso de Argo CD con acceso de escritura para un repositorio que es (o puede ser) usado en una aplicación de tipo directorio puede cometer un enlace simbólico que apunte a un archivo fuera de límites. Los archivos confidenciales que podrían filtrarse incluyen los archivos de manifiesto de los repositorios de fuentes de otras Aplicaciones (potencialmente archivos descifrados, si está usando un plugin de descifrado) o cualquier secreto con formato JSON que haya sido montado como archivo en el servidor de repositorios. Ha sido publicado un parche para esta vulnerabilidad en las versiones 2.3.4, 2.2.9 y 2.1.15 de Argo CD. Los usuarios de las versiones 2.3.0 o superiores que no tengan aplicaciones de tipo Jsonnet/directorio pueden deshabilitar la herramienta de administración de configuración de Jsonnet/directorio como mitigación
