CVE-2024-50601Network attack vector

Session hijacking via unsanitized cookie and URL values

Published Nov 11, 2024 · Updated Nov 12, 2024

Cross-site scripting in Axigen WebMail allows remote attackers to execute JavaScript through crafted cookie and URL values. The _h parameter is rendered without sanitization, and the resulting script can rewrite themeMode or other persistent cookies that WebMail later reflects without sanitization. A victim must process crafted input in an active WebMail context; successful execution can expose session data or perform actions as that user.
