The vulnerability CVE-2025-43788 is a broken access control flaw in the organization selector component of Liferay Portal and Liferay DXP. It functions due to a missing permission check on a specific server-side endpoint or API call that retrieves organization data. When an authenticated user, regardless of their specific role or privileges within the portal, sends a request to this endpoint, the application fails to validate whether the user is authorized to view organizational information. This flawed logic allows the server to process the request without applying the intended security constraints. Consequently, the server responds to the unauthorized request by serializing and returning a complete list of all organizations configured within the system. The attack complexity is low, requiring only a standard authenticated session and a crafted web request. The core failure is the application’s assumption that the user interface would enforce permissions, while the underlying data-fetching mechanism neglects to re-verify them on the server-side. This results in confidential structural data about the business or entity operating the portal being disclosed to users who should not have access to it.

Analytics
Check running Liferay version from bundle find /opt -name "liferay-portal-.jar" -o -name "liferay-dxp-.jar" | head -1 Simulate HTTP request to selector endpoint curl -k -s -H "Cookie: JSESSIONID=VALID_SESSION" "https://TARGET/api/jsonws/expandocolumn/get-organization-list" Search logs for organization-related access grep -i "organization.selector" /opt/liferay/tomcat-9.0.40/logs/catalina.out
How Exploit:
1. Attacker obtains valid user credentials (any role).
2. Attacker authenticates to the Liferay portal.
- Attacker intercepts or crafts a request to the organization selector backend endpoint.
4. Server processes request without permission validation.
- Server responds with full organization list in JSON/XML format.
- Attacker parses response to map internal organizational structure.
Protection from this CVE:
1. Apply vendor patch.
2. Implement network access controls.
3. Add custom permission validation.
4. Monitor audit logs.
5. Review user privileges.
Impact:
- Direct: Unauthorized data access.
- Secondary: Reconnaissance for targeted attacks.
- Business: Privacy regulation violations.
- Operational: Loss of trust.
