CVE-2025-62262 is a vulnerability classified under CWE-532, which concerns the insertion of sensitive information into log files. This issue affects Liferay Portal versions 7.4.0 through 7.4.3.97, Liferay DXP 2023.Q3.1 through 2023.Q3.4, and several older unsupported versions. The vulnerability arises from the LDAP import feature, which logs user email addresses in plaintext within system log files. Because these logs are accessible to local users with high privileges, sensitive information is exposed, potentially violating privacy and data protection policies. The vulnerability does not allow remote exploitation or require user interaction, but it does require local access with elevated privileges. The CVSS 4.6 score reflects that the attack vector is local, with low impact on confidentiality beyond email exposure, and no impact on integrity or availability. No patches are currently linked, indicating that remediation may require vendor updates or configuration changes. While no exploits are known in the wild, the presence of sensitive data in logs could be leveraged for social engineering or targeted attacks. The vulnerability highlights the importance of secure logging practices, especially in environments handling personal data.

For European organizations, this vulnerability poses a privacy risk by exposing user email addresses in logs accessible to privileged local users. Given the stringent requirements of GDPR and other data protection regulations in Europe, unauthorized exposure of personal data—even within internal logs—can lead to compliance violations, reputational damage, and potential fines. Although the vulnerability does not directly compromise system integrity or availability, the leakage of email addresses could facilitate phishing, spear-phishing, or insider threats. Organizations with large user bases or sensitive user data are at higher risk. The requirement for local privileged access limits the threat to insiders or attackers who have already gained elevated access, but this does not eliminate the risk, especially in multi-tenant or shared environments. The lack of remote exploitability reduces the risk of widespread automated attacks but does not diminish the need for prompt mitigation.

1. Restrict access to log files strictly to necessary system administrators and service accounts to minimize exposure. 2. Review and modify LDAP import logging configurations to avoid logging sensitive user information such as email addresses. 3. Monitor and audit local user activities, especially those with high privileges, to detect unauthorized access to logs. 4. Apply vendor patches or updates as soon as they become available to address this vulnerability directly. 5. Implement log management solutions that support encryption and access controls to protect sensitive log data. 6. Conduct regular security awareness training for administrators to highlight risks associated with sensitive data in logs. 7. Consider isolating or sandboxing the LDAP import process to limit the scope of log exposure. 8. Evaluate the necessity of logging sensitive fields and apply data minimization principles to logging practices.
