CVE-2025-0976: Hitachi Ops Center Information Disclosure

CVE-2025-0976 Overview

CVE-2025-0976 is an Information Exposure vulnerability affecting Hitachi Ops Center API Configuration Manager and Hitachi Configuration Manager. This vulnerability is classified under CWE-532 (Insertion of Sensitive Information into Log File), indicating that sensitive data may be inadvertently written to log files where it could be accessed by unauthorized users with local access to the system.

Critical Impact

Local attackers with low privileges could potentially access sensitive information exposed through improper logging practices, leading to confidentiality breaches in enterprise storage management environments.

Affected Products

• Hitachi Ops Center API Configuration Manager: versions 10.0.0-00 through 11.0.4-00
• Hitachi Configuration Manager: versions 8.6.1-00 through 11.0.5-00

Technical Details for CVE-2025-0976

Vulnerability Analysis

This vulnerability stems from improper handling of sensitive information within the logging mechanisms of Hitachi's configuration management products. The weakness allows sensitive data to be written to log files, which can then be accessed by local users who have read permissions to those files. While the attack requires local access and certain conditions to be met for successful exploitation, the potential impact on confidentiality is significant as authentication credentials, configuration details, or other sensitive operational data could be exposed.

The local attack vector requires an attacker to already have some level of access to the target system. Despite requiring low privileges, the complexity of exploitation is high, meaning specific conditions must align for successful data extraction. However, if exploited successfully, the confidentiality impact is high while integrity and availability remain unaffected.

Root Cause

The root cause of CVE-2025-0976 lies in CWE-532: Insertion of Sensitive Information into Log File. The affected Hitachi products write sensitive information to log files without proper sanitization or protection mechanisms. This design flaw allows users with local system access to potentially read sensitive data from log files that should have been protected or excluded from logging entirely.

Attack Vector

The attack vector for this vulnerability is local, requiring the attacker to have existing access to the system where the vulnerable Hitachi software is installed. An attacker would need to:

1. Gain local access to a system running the affected Hitachi Configuration Manager or Ops Center API Configuration Manager
2. Navigate to log file locations used by the affected software
3. Read log files containing inadvertently exposed sensitive information

The vulnerability does not require user interaction and operates within the scope of the affected component. While the attack complexity is high, successful exploitation could yield high-impact confidentiality breaches.

Detection Methods for CVE-2025-0976

Indicators of Compromise

• Unexpected access to log file directories associated with Hitachi Configuration Manager
• Unusual read operations on log files by non-administrative user accounts
• Evidence of log file exfiltration or copying to unauthorized locations

Detection Strategies

• Monitor file access events on Hitachi Configuration Manager log directories using endpoint detection tools
• Implement file integrity monitoring on sensitive log file locations
• Review access control lists on log directories to identify unauthorized permission changes
• Configure SentinelOne to alert on suspicious access patterns to configuration management log files

Monitoring Recommendations

• Enable detailed audit logging for file system access on servers running affected Hitachi products
• Deploy SentinelOne Singularity Platform to monitor for behavioral indicators of log file reconnaissance
• Establish baseline access patterns for legitimate log file access and alert on deviations

How to Mitigate CVE-2025-0976

Immediate Actions Required

• Upgrade Hitachi Ops Center API Configuration Manager to version 11.0.4-00 or later
• Upgrade Hitachi Configuration Manager to version 11.0.5-00 or later
• Review and restrict file system permissions on log file directories to minimize exposure
• Audit which users have local access to systems running affected software

Patch Information

Hitachi has released security updates to address this vulnerability. According to the Hitachi Security Advisory 2026-110, administrators should upgrade to the following versions:

• Hitachi Ops Center API Configuration Manager: Version 11.0.4-00 or later
• Hitachi Configuration Manager: Version 11.0.5-00 or later

Workarounds

• Restrict local access to systems running the affected Hitachi products to only essential personnel
• Implement strict file system permissions on log directories to prevent unauthorized read access
• Consider relocating log files to secured directories with enhanced access controls
• Enable log rotation and automated deletion of older log files to reduce exposure window

# Configuration example: Restrict log directory permissions
# Adjust paths according to your Hitachi installation
chmod 750 /opt/hitachi/configmanager/logs
chown root:hitachi-admins /opt/hitachi/configmanager/logs
# Enable log rotation to limit exposure
# Add to /etc/logrotate.d/hitachi-configmanager
# /opt/hitachi/configmanager/logs/*.log {
#     daily
#     rotate 7
#     compress
#     delaycompress
#     missingok
#     notifempty
# }
