CVE-2024-6741Network attack vector

Session-cookie disclosure via HttpOnly flag bypass

Published Jul 15, 2024 · Updated Aug 1, 2024

Protection-mechanism failure in Openfind Mail2000 V7.0 and V8.0 allows remote attackers to read HttpOnly session cookies via JavaScript. Mail2000's webmail cookie handling leaves an HttpOnly-protected session cookie accessible to specially crafted client-side JavaScript; the affected CGI, parameter, and faulty code operation are undisclosed. No authentication or user interaction is required, and the documented consequence is limited to session-cookie disclosure rather than data modification or service interruption.
