Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Kaleo Forms Admin in Liferay Portal 7.0.0 through 7.4.3.4, and Liferay DXP 7.4 GA, 7.3 GA through update 27, and older unsupported versions does not restrict the saving of request parameters in the portlet session, which allows remote attackers to consume system memory leading to denial-of-service (DoS) conditions via crafted HTTP request.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Kaleo Forms Admin portlet in Liferay Portal and DXP does not restrict the saving of request parameters in the portlet session, allowing attackers to send crafted HTTP requests that cause unbounded session data storage, leading to memory exhaustion and denial-of-service.

MitigationApply Liferays security patches or upgrade to a patched version (7.4.3.5+, 7.3 update 28+). Additionally, configure session size limits and monitor for anomalous session growth.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify LiferPortal or DXP installation version
    Access the LiferControl Panel > Configuration > Server Administration > Product Information, or check the osgi/state directory for the bundle version manifest
    Affected if The installed version is below 7.4.3.5 (for 7.4.x releases) or below 7.3 update 28 (for 7.3.x releases)
  2. Confirm Kaleo Forms Admin portlet is deployed
    Check the Liferapplication manager or deploy directory for kaleo-forms-admin-portlet WAR, or navigate to the Kaleo Forms Admin portlet in the Control Panel under Dynamic Data Lists
    Affected if The Kaleo Forms Admin portlet is installed and accessible in the Liferenvironment
  3. Verify session storage configuration
    Check the Liferportal-ext.properties or portal-setup-wizard.properties for session.maxInactiveInterval and check if session.size.limit or related session throttling is configured
    Affected if No session size limits are configured, allowing unbounded session data growth
  4. Check for anomalous session growth
    Monitor Lifer-server memory usage or inspect session attributes via JMX console for unusually large session data, particularly related to portlet request parameters
    Affected if Sessions contain unexpectedly large or unbounded data structures

The environment is affected if running a LiferPortal or DXP version below 7.4.3.5 or 7.3 update 28 AND the Kaleo Forms Admin portlet is deployed and accessible, with no session size limits configured.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Liferays security patches or upgrade to a patched version (7.4.3.5+, 7.3 update 28+). Additionally, configure session size limits and monitor for anomalous session growth.

Recommended fix Moderate confidence

Lifer Portal 7.4.3.5+ or Lifer DXP 7.3 Update 28+ / 7.4 GA+ with latest fixes

  1. 1. Identify the current Lifer Portal or DXP version currently running in production
  2. 2. Schedule a maintenance window for the upgrade process
  3. 3. Perform a complete backup of the Lifer database and the current Lifer installation directory
  4. 4. Upgrade Lifer Portal to version 7.4.3.5 or later (or the latest 7.4.x stable release)
  5. 5. For Lifer DXP users: Upgrade to 7.3 Update 28 or later, or to DXP 7.4 GA with latest fixes
  6. 6. After upgrade, verify the Kaleo Forms Admin portlet is functioning correctly
  7. 7. Monitor system memory usage to confirm the resource consumption issue is resolved
Caveat Patch releases typically have minimal breaking changes, but test the upgrade in a staging environment first to verify custom workflows and Kaleo Forms configurations work correctly
