CVE-2019-25046Network attack vector

Session hijacking via inline SVG script execution

Published Jun 10, 2021 · Updated Aug 5, 2024

Cross-site scripting in Cerberus FTP Server Enterprise before 10.0.19 and 11.0 through 11.0.3 allows remote attackers to hijack sessions. The HTTP(S) Web Client renders a user-supplied SVG inline with the image/svg+xml MIME type and executes embedded scripts in the end user's session context. Enterprise HTTP(S) listeners must permit SVG upload and download, and a user must preview the file; the script can act with that user's session authority.
