CVE-2025-30714
📋 TL;DR
This vulnerability in Oracle MySQL Connector/Python allows low-privileged attackers with network access to potentially access sensitive data through social engineering or user interaction. It affects MySQL Connector/Python versions 9.0.0 through 9.2.0 when used in applications that expose the connector functionality.
💻 Affected Systems
- Oracle MySQL Connector/Python
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete unauthorized access to all data accessible through MySQL Connectors, potentially exposing sensitive database information.
Likely Case
Limited data exposure through targeted social engineering attacks requiring user interaction.
If Mitigated
Minimal impact with proper access controls, network segmentation, and user awareness training.
🎯 Exploit Status
Requires low privileged access, network access, and user interaction via multiple protocols.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 9.2.1 or later
Vendor Advisory: https://www.oracle.com/security-alerts/cpuapr2025.html
Restart Required: Yes
Instructions:
1. Check current MySQL Connector/Python version. 2. Upgrade to version 9.2.1 or later using pip: 'pip install mysql-connector-python --upgrade'. 3. Restart any applications using the connector.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to MySQL connectors to trusted networks only.
Configure firewall rules to limit connector access
Principle of Least Privilege
allReduce connector user privileges to minimum required for application functionality.
ALTER USER 'app_user'@'%' WITH GRANT OPTION; REVOKE ALL PRIVILEGES ON *.* FROM 'app_user'@'%'; GRANT SELECT, INSERT, UPDATE, DELETE ON app_db.* TO 'app_user'@'%';
🧯 If You Can't Patch
- Implement strict network access controls to limit connector exposure
- Enhance user awareness training about social engineering risks
🔍 How to Verify
Check if Vulnerable:
Check installed MySQL Connector/Python version: 'python -c "import mysql.connector; print(mysql.connector.__version__)"'Check Version:
python -c "import mysql.connector; print(mysql.connector.__version__)"Verify Fix Applied:
Verify version is 9.2.1 or higher using same command and test connector functionality.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts to MySQL connectors
- Multiple failed connection attempts from unexpected sources
Network Indicators:
- Unexpected network traffic to MySQL connector ports (default 3306)
- Connection attempts from unauthorized IP ranges
SIEM Query:
source="mysql.log" AND (event_type="authentication_failure" OR event_type="connection_attempt") AND src_ip NOT IN (trusted_ips)
