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).","published":"2020-02-05T17:15:10.537Z","modified":"2026-08-07T15:14:43.560462Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.948,"percentile":0.99853,"asOf":"2026-09-08"},"cisaKev":null,"exploitsKnown":2,"affectedPackages":[],"fix":null,"references":[{"type":"EVIDENCE","url":"https://dotcms.com/security/SI-54"},{"type":"EVIDENCE","url":"https://github.com/dotCMS/core/issues/17796"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T15:14:43.560462Z"}}
