Security readout for executives and security teams

MailEnable Enterprise Premium 10.23 had stored and reflected XSS that could let an attacker run script in a user’s browser. The source description says the session cookie lacked HttpOnly, so successful XSS could expose the user’s session cookie and enable account hijacking. Exposure is most likely where MailEnable Enterprise Premium 10.23 web interfaces are used, especially internet-facing webmail or administrative access. The affected-product metadata is incomplete in the bundle, so validate against installed versions and vendor release notes. Prioritize remediation for internet-facing or privileged MailEnable portals. Business risk is account takeover through user browser compromise, but urgency is tempered by no cited active exploitation and incomplete severity data. Mitigation focus: Identify any MailEnable Enterprise Premium 10.23 deployments.; Review MailEnable release notes and NCC Group advisory for vendor-confirmed remediation.; Upgrade or apply vendor guidance if a fixed release is confirmed..
