Redmine 0.8.7 and earlier uses the title tag before defining the character encoding in a meta tag, which allows remote attackers to conduct cross-site scripting (XSS) attacks and inject arbitrary script via UTF-7 encoded values in the title parameter to a new issue page, which may be interpreted as script by Internet Explorer 7 and 8.

Security readout for executives and security teams

CVE-2009-4459 is a cross-site scripting issue in Redmine 0.8.7 and earlier. A malicious value in a new issue page title parameter could run script in Internet Explorer 7 or 8 because character encoding was declared too late in the page. Exposure is most likely in legacy Redmine deployments at version 0.8.7 or earlier, especially if reachable by users with Internet Explorer 7 or 8 compatibility requirements. Treat this as a legacy exposure cleanup item with moderate urgency. Risk rises if old Redmine remains internet-facing or used with legacy Internet Explorer clients. Mitigation focus: Inventory Redmine instances and confirm whether any are version 0.8.7 or earlier.; Check Redmine vendor guidance for the supported fix or upgrade path.; Prioritize removing internet exposure from affected legacy Redmine systems..
