Details

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 $TOMCATHOME/webapps/ROOT/assets (which should be a protected directory). Additionally, attackers can upload temporary files (e.g., .jsp files) into /webapps/ROOT/assets/tmpupload, which can lead to remote command execution (with the permissions of the user running the dotCMS application).
