CVE-2025-30722: Oracle MySQL Cluster Info Disclosure Flaw

CVE-2025-30722 Overview

CVE-2025-30722 is a vulnerability in the MySQL Client product of Oracle MySQL, specifically affecting the mysqldump component. This security flaw allows a low-privileged attacker with network access to potentially compromise MySQL Client installations, leading to unauthorized access to critical data or complete access to all MySQL Client accessible data, as well as unauthorized modification capabilities.

Critical Impact

Successful exploitation enables attackers to gain unauthorized access to sensitive database information and perform unauthorized data manipulation operations on affected MySQL Client installations.

Affected Products

• Oracle MySQL Client versions 8.0.0 through 8.0.41
• Oracle MySQL Client versions 8.4.0 through 8.4.4
• Oracle MySQL Client versions 9.0.0 through 9.2.0
• Oracle MySQL Cluster (multiple affected version ranges)
• NetApp Active IQ Unified Manager for VMware vSphere and Windows
• NetApp SnapCenter

Discovery Timeline

• April 15, 2025 - CVE-2025-30722 published to NVD
• November 3, 2025 - Last updated in NVD database

Technical Details for CVE-2025-30722

Vulnerability Analysis

This vulnerability exists within the mysqldump component of Oracle MySQL Client. The flaw is classified as difficult to exploit, requiring the attacker to have low-level privileges and network access via multiple protocols. When successfully exploited, the vulnerability compromises both the confidentiality and integrity of data accessible through the MySQL Client.

The attack does not require user interaction, making it exploitable in automated scenarios once an attacker has established the necessary network access and obtained low-privileged credentials. The vulnerability's scope is unchanged, meaning the impact is limited to the vulnerable component itself rather than affecting other system components.

Root Cause

The root cause has not been publicly disclosed by Oracle beyond identifying it as affecting the mysqldump utility. The CWE classification (NVD-CWE-noinfo) indicates insufficient information is available to categorize the specific weakness type. Based on the impact characteristics, the vulnerability likely involves improper access control or input validation within the mysqldump component that allows authenticated users to access or modify data beyond their authorized scope.

Attack Vector

The vulnerability is exploited over the network, requiring the attacker to have:

1. Network connectivity to the target MySQL Client installation
2. Low-privileged authentication credentials
3. Ability to interact with the mysqldump utility

The attack complexity is high, meaning specific conditions must be met beyond the attacker's control for successful exploitation. The attacker leverages the mysqldump component to gain unauthorized read access to critical data and limited write access to modify, insert, or delete certain data. No availability impact has been identified, indicating the vulnerability does not enable denial of service attacks.

Given that no verified code examples are available for this vulnerability, organizations should refer to the Oracle Security Alert April 2025 for detailed technical information about the exploitation mechanism and indicators of compromise specific to their environment.

Detection Methods for CVE-2025-30722

Indicators of Compromise

• Unusual mysqldump process execution by unauthorized or unexpected user accounts
• Abnormal network connections to MySQL services from untrusted sources
• Unexpected data exports or backup operations initiated without authorization
• Audit log entries showing mysqldump operations accessing data outside normal patterns

Detection Strategies

• Monitor for anomalous mysqldump command executions, particularly those targeting sensitive databases or schemas
• Implement database activity monitoring to detect unauthorized SELECT operations or data modifications
• Review authentication logs for suspicious login attempts followed by mysqldump activity
• Deploy network monitoring to identify unusual traffic patterns to MySQL ports from unexpected sources

Monitoring Recommendations

• Enable MySQL audit logging to capture all mysqldump operations and associated user context
• Configure SIEM rules to alert on mysqldump executions outside of scheduled backup windows
• Implement file integrity monitoring on systems where mysqldump output files are stored
• Monitor for bulk data extraction patterns that may indicate exploitation attempts

How to Mitigate CVE-2025-30722

Immediate Actions Required

• Apply the latest Oracle Critical Patch Update (CPU) from April 2025 to all affected MySQL installations
• Review and restrict user privileges to minimize the number of accounts with mysqldump access
• Implement network segmentation to limit access to MySQL services from trusted sources only
• Audit existing database user accounts and remove unnecessary privileges

Patch Information

Oracle has released security patches addressing CVE-2025-30722 as part of the April 2025 Critical Patch Update. Organizations should apply the appropriate patches based on their MySQL version:

• MySQL 8.0.x users should upgrade to version 8.0.42 or later
• MySQL 8.4.x users should upgrade to version 8.4.5 or later
• MySQL 9.x users should upgrade to version 9.2.1 or later

For detailed patch information and download links, refer to the Oracle Security Alert April 2025.

NetApp customers should review the NetApp Security Advisory NTAP-20250418-0005 for guidance on updating affected Active IQ Unified Manager and SnapCenter installations.

Debian users should consult the Debian LTS Announcement June 2025 for distribution-specific update instructions.

Workarounds

• Restrict mysqldump utility access to only essential administrative accounts until patches can be applied
• Implement strict network access controls limiting MySQL connectivity to approved hosts and networks
• Use application-layer firewalls to monitor and filter mysqldump-related traffic patterns
• Consider temporarily disabling remote mysqldump access if operationally feasible

# Example: Restrict mysqldump access via user privileges
# Revoke unnecessary privileges from non-administrative users
REVOKE ALL PRIVILEGES ON *.* FROM 'limited_user'@'%';
GRANT SELECT ON specific_database.* TO 'limited_user'@'localhost';
FLUSH PRIVILEGES;
