CVE-2012-2593Public exploitNetwork attack vector

Administrator-session script execution via unsanitized Date header

Published Feb 6, 2020 · Updated Aug 6, 2024

Stored cross-site scripting in Atmail Webmail Server 6.4 allows remote attackers to run script in an administrator browser via email. The administrative interface renders an email's untrusted Date header as HTML without neutralizing script markup, so a crafted header loads attacker-controlled JavaScript. Execution requires the administrator to have the interface open when the message arrives; the published exploit chains that session into a CSRF plugin upload and server-side code execution.
