Security readout for executives and security teams
CVE-2009-3742 is a cross-site scripting issue in Liferay Portal before 5.3.0. A remote attacker could inject script or HTML through the p_p_id parameter. For executives, the concern is user trust, session exposure, and portal integrity if old Liferay deployments remain online. Likely exposure is limited to organizations still running Liferay Portal versions earlier than 5.3.0. Internet-facing portals are the main concern. The bundle does not identify affected CPEs, specific configurations, or whether default installations are vulnerable. Treat this as a legacy exposure cleanup item with moderate urgency. It is not KEV-listed in the provided bundle, but externally reachable old portal software can create account and trust risks if left unremediated. Mitigation focus: Identify any Liferay Portal deployments and record exact versions.; Upgrade versions earlier than 5.3.0 following Liferay guidance.; Review Liferay issue LPS-6034 and CERT VU#750796 for vendor-specific direction..
