CVE-2025-62262 is an information exposure vulnerability classified under CWE-532, which involves the insertion of sensitive information into log files. It affects Liferay Portal versions 7.4.0 through 7.4.3.97, older unsupported versions, and Liferay DXP versions from 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92, and 7.3 GA through update 35. The vulnerability arises from the LDAP import feature, which logs user email addresses in plaintext within system log files. These logs are accessible to local users with high privileges, potentially allowing unauthorized access to sensitive personal information. The CVSS 4.0 vector indicates that exploitation requires local access (AV:L), low attack complexity (AC:L), no authentication bypass (PR:H), no user interaction (UI:N), and results in low confidentiality impact (VC:L) with no integrity or availability impact. Although no known exploits exist in the wild, the exposure of email addresses can facilitate further social engineering or phishing attacks. The vulnerability does not affect system integrity or availability but poses a privacy risk and compliance concern, especially under regulations like GDPR. No official patches have been linked yet, so mitigation relies on access control and logging configuration adjustments.

For European organizations, this vulnerability primarily threatens the confidentiality of user email addresses, which are considered personal data under GDPR. Unauthorized access to such data can lead to privacy violations, regulatory penalties, and reputational damage. Since the vulnerability requires local access with high privileges, the risk is elevated in environments where multiple users have administrative or elevated rights on Liferay Portal servers. Attackers or malicious insiders gaining such access could extract email addresses from logs and use them for targeted phishing or identity theft. The exposure does not directly impact system availability or integrity but can undermine trust in the organization's data protection practices. Organizations in sectors with strict data privacy requirements, such as finance, healthcare, and government, face higher compliance risks. Additionally, the lack of patches increases the window of exposure until remediation is available.

1. Restrict access to log files strictly to trusted administrators and system processes to prevent unauthorized local users from reading sensitive logs. 2. Review and modify the LDAP import logging configuration to minimize or eliminate logging of sensitive information such as email addresses. 3. Implement file system permissions and auditing on log directories to detect and prevent unauthorized access. 4. Monitor user accounts with elevated privileges and enforce the principle of least privilege to reduce the number of users who can access logs. 5. Consider deploying host-based intrusion detection systems (HIDS) to alert on suspicious access to log files. 6. Stay informed on Liferay’s official security advisories for patches or updates addressing this vulnerability and apply them promptly once available. 7. Conduct regular security reviews and compliance audits focusing on data exposure risks in logging and monitoring configurations. 8. Educate system administrators about the risks of sensitive data in logs and best practices for secure logging.
