      "value": "Opencast is a free, open-source platform to support the management of educational audio and video content. In version 18.0 and versions before 17.7, the protections against path traversal attacks in the UI config module are insufficient, still partially allowing for attacks in very specific cases. The path is checked without checking for the file separator. This could allow attackers access to files within another folder which starts with the same path. This issue has been fixed in versions 17.7 and 18.1. To mitigate this issue, check for folders that start with the same path as the ui-config folder."

En la versión 18.0 y versiones anteriores a la 17.7, las protecciones contra ataques de salto de ruta en el módulo UI config son insuficientes, aún permitiendo parcialmente ataques en casos muy específicos. La ruta se verifica sin verificar el separador de archivos. Esto podría permitir a los atacantes acceder a archivos dentro de otra carpeta que comienza con la misma ruta. Este problema ha sido solucionado en las versiones 17.7 y 18.1. Para mitigar este problema, verifique las carpetas que comienzan con la misma ruta que la carpeta 'ui-config'."
