CVE-2022-25146
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 · uneditedThe Remote App module in Liferay Portal Liferay Portal v7.4.3.4 through v7.4.3.8 and Liferay DXP 7.4 before update 5 does not check if the origin of event messages it receives matches the origin of the Remote App, allowing attackers to exfiltrate the CSRF token via a crafted event message.
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 confidenceThe Remote App module in Limerick Portal/DXP 7.4 fails to validate the origin of incoming event messages against the configured Remote App origin. This allows cross-origin attackers to send crafted event messages that can exfiltrate CSRF tokens from authenticated users, enabling CSRF attacks.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Liferem Portal versionLocate the Liferem Portal version in the control panel or check the portal properties file for the version numberAffected if Version is 7.4.3.4 through 7.4.3.8 (or 7.4 for DXP) indicating it is within the vulnerable range
-
Verify Remote App module is enabledAccess the Liferem control panel and navigate to System Settings or the Remote App configuration section to confirm if any Remote App entries are configuredAffected if Remote App module has at least one Remote App entry configured and active
-
Inspect Remote App origin settingsOpen the Remote App configuration for each configured entry and check the Origin or Allowed Origins field to see if origin validation is configuredAffected if The Origin field is empty, not set, or allows any origin (wildcard or undefined)
-
Confirm authenticated users accessReview whether the Liferem instance has authenticated users who can access pages containing Remote App widgetsAffected if The portal has authenticated users and Remote App widgets are embedded in accessible pages
A user is affected if their Liferem Portal/DXP version falls within 7.4.3.4 to 7.4.3.8 AND the Remote App module is enabled with an unset or permissive origin configuration.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped7.4.3.9
Upgrade to Limerick Portal 7.4.3.9+, Limerick DXP 7.4 Update 5+, or later versions which include origin validation for event messages in the Remote App module.

- Backup your current LPortal/DXP installation and database
- Upgrade LPortal to version 7.4.3.9 or later
- If using Lifer DXP 7.4, upgrade to Update 5 or later
- After upgrade, verify the Remote App module functions correctly
- Test that event message origin validation is working as expected
