All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, the said component extracts a user-controlled tar.gz file without validating the size of its inner files. As a result, a malicious, low-privileged user can send a malicious tar.gz file that exploits this vulnerability to the repo-server, thereby harming the system's functionality and availability. Additionally, the repo-server is susceptible to another vulnerability due to the fact that it does not check the extracted file permissions before attempting to delete them. Consequently, an attacker can craft a malicious tar.gz archive in a way that prevents the deletion of its inner files when the manifest generation process is completed. A patch for this vulnerability has been released in versions 2.6.15, 2.7.14, and 2.8.3. Users are advised to upgrade. The only way to completely resolve the issue is to upgrade, however users unable to upgrade should configure RBAC (Role-Based Access Control) and provide access for configuring applications only to a limited number of administrators. These administrators should utilize trusted and verified Helm charts."}, {"lang": "es", "value": "Argo CD es una implementaci\u00f3n continua declarativa para Kubernetes. Todas las versiones de ArgoCD a partir de la v2.4 tienen un error por el cual el componente del servidor de repositorio de ArgoCD es vulnerable a un vector de ataque de denegaci\u00f3n de servicio. Espec\u00edficamente, dicho componente extrae un archivo tar.gz controlado por el usuario sin validar el tama\u00f1o de sus archivos internos. Como resultado, un usuario malicioso y con pocos privilegios puede enviar un archivo tar.gz malicioso que aproveche esta vulnerabilidad al servidor de repositorio, da\u00f1ando as\u00ed la funcionalidad y disponibilidad del sistema. Adem\u00e1s, el servidor del repositorio es susceptible a otra vulnerabilidad debido a que no verifica los permisos de los archivos extra\u00eddos antes de intentar eliminarlos. En consecuencia, un atacante puede crear un archivo tar.gz malicioso de manera que impida la eliminaci\u00f3n de sus archivos internos cuando se completa el proceso de generaci\u00f3n del manifiesto. Se lanz\u00f3 un parche para esta vulnerabilidad en las versiones 2.6.15, 2.7.14 y 2.8.3. Se recomienda a los usuarios que actualicen. La \u00fanica forma de resolver completamente el problema es actualizar; sin embargo, los usuarios que no puedan actualizar deben configurar RBAC (Control de Acceso Basado en Roles) y brindar acceso para configurar aplicaciones solo a un n\u00famero limitado de administradores.
