include/iniset.php in Roundcube Webmail 0.5.4 and earlier, when PHP 5.3.7 or 5.3.8 is used, allows remote attackers to trigger a GET request for an arbitrary URL, and cause a denial of service (resource consumption and inbox outage), via a Subject header containing only a URL, a related issue to CVE-2011-3379.

Security readout for executives and security teams

This vulnerability affects very old Roundcube Webmail deployments using PHP 5.3.7 or 5.3.8. A specially formed email subject could make Roundcube request an arbitrary URL and consume resources, potentially making a user's inbox unavailable. The sources do not provide a CVSS score or confirm active exploitation. Exposure is most likely in legacy Roundcube Webmail installations at version 0.5.4 or earlier running on PHP 5.3.7 or 5.3.8. Modern, supported Roundcube and PHP deployments are less likely to match the described conditions, but the bundle does not list fixed versions. Prioritize if legacy Roundcube webmail remains in use, especially for customer-facing or executive mailboxes. The business impact is availability loss rather than confirmed data theft. If no matching legacy deployment exists, this should be tracked as a hygiene item. Mitigation focus: Inventory Roundcube Webmail and PHP versions across all mail platforms.; Remove the vulnerable Roundcube and PHP version combination from production.; Check Roundcube, OS vendor, or appliance guidance for fixed supported packages..
