CVE-2009-3757: Multiple cross-site scripting (XSS) vulnerabilities in sample code in the XenServer Resource Kit in Citrix...

Security readout for executives and security teams

CVE-2009-3757 describes multiple XSS flaws in Citrix XenCenterWeb sample code from the XenServer Resource Kit. If that sample web code is deployed, an attacker may inject script or HTML through named request parameters. The bundle does not provide CVSS, affected version detail, or vendor remediation guidance. Exposure is likely limited to environments that deployed Citrix XenCenterWeb sample code from the XenServer Resource Kit. The source bundle does not identify supported versions, CPEs, or whether production XenCenter components are affected. Prioritize confirmation over broad emergency response. If the sample XenCenterWeb code is exposed, reduce access quickly and seek vendor guidance. If the code is absent, business risk is likely low. Mitigation focus: Identify any deployed XenCenterWeb or XenServer Resource Kit sample PHP pages.; Remove or disable sample code that is not operationally required.; Restrict access to management web interfaces to trusted administrative networks..
