CVE-2020-3796Network attack vector

System file structure disclosure via improper access control

Published Jun 26, 2020 · Updated Aug 4, 2024

Improper access control in Adobe ColdFusion 2016 Update 14 and earlier and 2018 Update 8 and earlier allows remote attackers to disclose file structure. Adobe has not published the affected component, request path, or incorrect authorization operation that exposes the server's system file structure. Network reachability and user interaction are required; published sources limit the consequence to file-structure disclosure and do not report file-content access or modification.
