CVE-2020-6754: dotCMS

Critical severity, CVSS 9.8. EPSS: 94.8% chance of exploitation in the next 30 days.

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).
