"value": "OpenOlat is a web-basedlearning management system. A path traversal vulnerability exists in OpenOlat prior to versions 15.5.12 and 16.0.5. By providing a filename that contains a relative path as a parameter in some REST methods, it is possible to create directory structures and write files anywhere on the target system. The attack could be used to write files anywhere in the web root folder or outside, depending on the configuration of the system and the properly configured permission of the application server user. The attack requires an OpenOlat user account, an enabled REST API and the rights on a business object to call the vulnerable REST calls. The problem is fixed in version 15.5.12 and 16.0.5. There is a workaround available. The vulnerability requires the REST module to be enabled. Disabling the REST module or limiting the REST module via some firewall or web-server access rules to be accessed only be trusted systems will mitigate the risk."

"value": "OpenOlat es un sistema de administraci\u00f3n de aprendizaje basado en la web. Se presenta una vulnerabilidad de salto de ruta en OpenOlat versiones anteriores a 15.5.12 y 16.0.5. Al proporcionar un nombre de archivo que contiene una ruta relativa como par\u00e1metro en algunos m\u00e9todos REST, es posible crear estructuras de directorio y escribir archivos en cualquier lugar del sistema de destino. El ataque podr\u00eda ser usado para escribir archivos en cualquier lugar de la carpeta root de la web o fuera de ella, dependiendo de la configuraci\u00f3n del sistema y del permiso correctamente configurado del usuario del servidor de aplicaciones. El ataque requiere una cuenta de usuario OpenOlat, una API REST habilitada y los derechos sobre un objeto de negocio para llamar a las llamadas REST vulnerables. El problema ha sido corregido en las versiones 15.5.12 y 16.0.5. Se presenta una soluci\u00f3n disponible. La vulnerabilidad requiere que el m\u00f3dulo REST est\u00e9 habilitado. Deshabilitar el m\u00f3dulo REST o limitar el m\u00f3dulo REST por medio de alg\u00fan firewall o regla de acceso al servidor web para que s\u00f3lo sea accedido a sistemas confiables mitigar\u00e1 el riesgo"
