The CVE-2025-XXXX vulnerability in Liferay Portal stems from an information exposure flaw within the LDAP import functionality. During the process of importing user data from an LDAP directory, the application logs sensitive information, specifically user email addresses, into log files. This occurs without proper sanitization or access controls on these log files. The mechanism does not differentiate between sensitive and non-sensitive data during the logging operation for LDAP synchronization events. Consequently, any local user with read access to the application’s log directories can extract personally identifiable information (PII) from the log entries. The vulnerability is present when the LDAP import feature is utilized, causing email addresses to be written in plaintext to log files that are accessible at the filesystem level.
Platform: Liferay Portal/DXP
Version: 7.4.0-7.4.3.97
Vulnerability : Information Exposure
Severity: Moderate
date: 2025-10-27
Prediction: 2025-11-17
What Undercode Say:
grep -r "userEmail=" /opt/liferay/logs/
tail -f /opt/liferay/logs/liferay..log | grep --line-buffered "LDAPImport"
find /opt/liferay/logs -name ".log" -mtime -1 -exec grep -l "@" {} \;
How Exploit:
Local user reads application logs containing unsanitized LDAP import data, extracting email addresses from the log entries written during directory synchronization.
Protection from this CVE
Upgrade to Liferay Portal version 4.0.54 or Liferay DXP fixed versions. Restrict filesystem permissions on log directories. Implement log filtering to redact PII before writing.
Impact:
Exposure of user email addresses, potential privacy violation, information disclosure to local attackers.
