Multiple cross-site request forgery (CSRF) vulnerabilities in Zimbra Collaboration before 8.7.0 allow remote attackers to hijack the authentication of unspecified victims via vectors involving (1) the Client uploader extension or (2) extension REST handlers, aka bugs 104294 and 104456.

Security readout for executives and security teams

CVE-2016-3406 describes multiple CSRF flaws in Zimbra Collaboration before 8.7.0. An attacker could abuse a signed-in user’s browser to perform actions through affected uploader or extension REST functionality. Business urgency depends on whether any legacy Zimbra systems remain below 8.7.0. Exposure is most likely in organizations still running Zimbra Collaboration versions earlier than 8.7.0. The bundle does not identify affected configurations beyond the product version and named components. Treat this as a legacy-platform exposure check rather than an emergency exploitation event. If Zimbra before 8.7.0 exists, prioritize upgrade or containment because mail systems carry high business value. Mitigation focus: Upgrade Zimbra Collaboration to 8.7.0 or later where supported.; Review Zimbra security advisories for bugs 104294 and 104456.; Identify and prioritize any internet-facing legacy Zimbra deployments..
