CVE-2024-6739Network attack vector

Session-cookie theft via missing HttpOnly attribute

Published Jul 15, 2024 · Updated Aug 1, 2024

Missing cookie protection in Openfind MailGates and MailAudit before V6.0 6.1.7.040 allows remote attackers to steal session cookies. The affected web interface issues its session cookie without the HttpOnly attribute, leaving the cookie readable to client-side JavaScript. An XSS context capable of executing JavaScript is the gate; the documented consequence is session-cookie disclosure, not data modification or service interruption.
