Executive Summary

CVE-2025-43768 is a vulnerability in Liferay Portal and Liferay DXP where authenticated users without any specific permissions can access sensitive information of admin users through the JSONWS API endpoint. This means that even users with minimal access rights can retrieve confidential admin data due to improper access controls in certain versions of the software. [1]

Detection Guidance

Detection involves monitoring access to the JSONWS API endpoints on affected Liferay Portal or DXP versions. You can check logs for authenticated users accessing JSONWS API paths without proper permissions. Specific commands depend on your environment, but for example, using curl to test access: curl -u <user>:<password> https://<liferay-host>/api/jsonws/ to see if sensitive admin information is returned without proper authorization. Additionally, reviewing web server or application logs for unusual JSONWS API access patterns by authenticated users without admin roles can help detect exploitation attempts. [1]

Mitigation Strategies

Immediate mitigation steps include upgrading Liferay Portal to version 7.4.3.132 or later, or Liferay DXP to 2025.Q1.0 or later, where the vulnerability is fixed. Until an upgrade is possible, restrict access to the JSONWS API endpoints to trusted users only, and monitor for suspicious access. Applying network-level controls such as firewall rules to limit access to the API and enforcing strong authentication policies can also reduce risk. [1]
