Security readout for executives and security teams
CVE-2015-5381 is a reflected cross-site scripting issue in Roundcube Webmail. An attacker could abuse the _mbox URL parameter to inject script or HTML into a user’s browser. Business risk depends on whether legacy Roundcube 1.1.x systems remain exposed and whether users can be lured to malicious links. Exposure is most likely in internet-accessible Roundcube Webmail deployments still running 1.1.x before 1.1.2. Organizations using newer maintained Roundcube releases are less likely exposed. The bundle does not identify other affected products or downstream packages. Treat this as a legacy webmail hygiene issue with moderate urgency. It is old and not KEV-listed, but exposed webmail is high-value. Prioritize confirmation that no public Roundcube instance remains on affected 1.1.x versions. Mitigation focus: Upgrade Roundcube Webmail 1.1.x deployments to 1.1.2 or a later supported release.; Review Roundcube’s 2015 update advisory and vendor package guidance for maintained branches.; Remove or isolate unsupported legacy Roundcube instances from internet exposure..
