CVE-2020-6754

dotCMS before 5.2.4 is vulnerable to directory traversal, leading to incorrect access control. It allows an attacker to read or execute files under $TOMCAT_HOME/webapps/ROOT/assets (which should be a protected directory). Additionally, attackers can upload temporary files (e.g., .jsp files) into /webapps/ROOT/assets/tmp_upload, which can lead to remote command execution (with the permissions of the user running the dotCMS application).

dotCMS versiones anteriores a 5.2.4, es vulnerable a salto de directorio, lo que conlleva a un control de acceso incorrecto. Permite a un atacante leer o ejecutar archivos bajo $TOMCAT_HOME/webapps/ROOT/assets (que debería ser un directorio protegido). Además, los atacantes pueden cargar archivos temporales (por ejemplo, archivos .jsp) en /webapps/ROOT/assets/tmp_upload, lo que puede conllevar a una ejecución de comandos remota (con los permisos del usuario que ejecuta la aplicación dotCMS).
