CVE-2019-19265Public exploitNetwork attack vector

User-assisted browser code execution via unsanitized vCard notes

Published Jan 6, 2020 · Updated Aug 5, 2024

Stored XSS in IceWarp WebMail Server 12.1.x and 12.2.0 allows remote attackers to run JavaScript through imported contact notes. The contact importer renders HTML from vCard NOTE and X-ALT-NOTE fields without neutralizing event-handler code. An IceWarp user must import the crafted vCard; the script then runs in that user's browser and can access session-visible mail and data.
