CVE-2020-6754 Information

Description

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).
