      "value": "Xerte Online Toolkits versions 3.15 and earlier contain a relative path traversal vulnerability in the elFinder connector endpoint at /editor/elfinder/php/connector.php where the name parameter in rename commands is not sanitized for path traversal sequences. Attackers can supply a name value containing directory traversal sequences to move files from project media directories to arbitrary locations on the filesystem, potentially overwriting application files, achieving stored cross-site scripting, or combining with other vulnerabilities to achieve unauthenticated remote code execution by moving PHP code files to the application root."

      "value": "Las versiones 3.15 y anteriores de Xerte Online Toolkits contienen una vulnerabilidad de salto de ruta relativo en el endpoint del conector elFinder en /editor/elfinder/php/connector.php donde el parámetro name en los comandos de renombrado no se sanea para secuencias de salto de ruta. Los atacantes pueden proporcionar un valor name que contenga secuencias de salto de directorio para mover archivos de directorios de medios del proyecto a ubicaciones arbitrarias en el sistema de archivos, potencialmente sobrescribiendo archivos de la aplicación, logrando cross-site scripting almacenado, o combinándose con otras vulnerabilidades para lograr ejecución remota de código no autenticada moviendo archivos de código PHP a la raíz de la aplicación."
