CVE-2019-3398 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Confluence Server and Data Center had a path traversal vulnerability in the downloadallattachments resource. A remote attacker who has permission to add attachments to pages and / or blogs or to create a new space or a personal space or who has 'Admin' permissions for a space can exploit this path traversal vulnerability to write files to arbitrary locations which can lead to remote code execution on systems that run a vulnerable version of Confluence Server or Data Center. CISA has confirmed active exploitation in the wild. EPSS estimates a 97.15% chance of exploitation in the next 30 days.
