CVE-2025-62242 is an authorization bypass vulnerability classified under CWE-639 (Authorization Bypass Through User-Controlled Key) affecting Liferay Portal and Liferay DXP products. The flaw exists in the handling of the _com_liferay_account_admin_web_internal_portlet_AccountEntriesAdminPortlet_addressId parameter, which is used to reference account addresses. Due to insufficient authorization checks, a remote authenticated user can manipulate this parameter to view address data belonging to other accounts, violating access control policies. The vulnerability affects multiple versions of Liferay Portal 7.4.3.x and Liferay DXP 2023 Q3 and Q4 releases, indicating a broad impact across recent product versions. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), no additional privileges beyond authentication (PR:L), and no user interaction (UI:N). The impact is limited to confidentiality (VC:L) with no integrity or availability impact. No public exploits have been reported, but the vulnerability could be leveraged to harvest sensitive address information, potentially leading to privacy violations or aiding further targeted attacks. The lack of patches at the time of publication necessitates immediate attention to access controls and monitoring.

For European organizations, this vulnerability poses a risk of unauthorized disclosure of sensitive customer or partner address information stored within Liferay Portal or DXP environments. Such data leaks can lead to privacy breaches, regulatory non-compliance (e.g., GDPR), reputational damage, and potential legal consequences. Organizations in sectors like finance, healthcare, government, and telecommunications that rely on Liferay for customer or account management are particularly vulnerable. The breach of address data could facilitate social engineering, identity theft, or targeted phishing attacks. Although the vulnerability does not affect system integrity or availability, the confidentiality impact alone is significant given the sensitivity of personal address data. The requirement for authentication limits exposure but does not eliminate risk, especially in environments with weak credential management or insider threats.

1. Apply vendor patches immediately once available to ensure the vulnerability is fully remediated. 2. Until patches are released, implement strict server-side authorization checks on the addressId parameter to verify that the requesting user has permission to access the referenced account address. 3. Conduct thorough access control reviews and audits of Liferay Portal and DXP configurations to identify and close any similar authorization gaps. 4. Monitor logs for unusual or unauthorized access patterns to account address data, focusing on parameter manipulation attempts. 5. Enforce strong authentication mechanisms and consider multi-factor authentication to reduce risk from compromised credentials. 6. Limit the exposure of the AccountEntriesAdminPortlet to trusted internal networks or VPNs where feasible. 7. Educate administrators and users about the risks of sharing credentials and the importance of reporting suspicious activity. 8. Regularly review and update security policies related to user access and data privacy compliance.
