How the CVE Works:
The vulnerability (CVE-2025-XXXX) in Apache Airflow MySQL Provider arises from improper neutralization of special elements in SQL commands, leading to SQL Injection. Specifically, the `dump_sql` and `load_sql` functions in the MySQL Provider allow users to pass a `table` parameter via the UI. If an attacker injects malicious SQL code into this parameter, it can execute unintended SQL commands on the database. This could result in unauthorized data access, data corruption, or modification. The issue affects versions of Apache Airflow MySQL Provider prior to 6.2.0. Upgrading to version 6.2.0 mitigates the vulnerability by properly sanitizing user inputs.
DailyCVE Form:
Platform: Apache Airflow
Version: Before 6.2.0
Vulnerability: SQL Injection
Severity: Moderate
Date: Mar 19, 2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
Malicious table parameter passed to dump_sql function malicious_table = "users; DROP TABLE users; --" result = dump_sql(malicious_table)
This code demonstrates how an attacker could inject a malicious SQL command to drop the `users` table.
2. Exploit via UI:
- Enter `table=users; DELETE FROM users; –` in the UI input field for the `table` parameter.
- The backend executes the unintended SQL command, leading to data loss.
Protection:
1. Upgrade:
- Upgrade to Apache Airflow MySQL Provider version 6.2.0 or later.
- Command: `pip install –upgrade apache-airflow-providers-mysql==6.2.0`
2. Input Sanitization:
- Implement input validation and sanitization for all user-provided inputs.
- Example:
import re def sanitize_input(input_str): return re.sub(r"[bash]", "", input_str) sanitized_table = sanitize_input(user_input)
3. Database Permissions:
- Restrict database user permissions to minimize damage from SQL Injection.
- Example:
GRANT SELECT, INSERT ON database. TO 'airflow_user'@'localhost'; REVOKE DROP, DELETE ON database. FROM 'airflow_user'@'localhost';
4. Logging and Monitoring:
- Enable detailed logging to detect suspicious SQL queries.
- Example:
SET GLOBAL log_output = 'FILE'; SET GLOBAL general_log = 'ON';
5. Web Application Firewall (WAF):
- Deploy a WAF to filter out malicious SQL Injection attempts.
- Example:
ModSecurity rule to block SQL Injection SecRule ARGS "@detectSQLi" "id:1001,deny,status:403"
6. Testing:
- Use tools like SQLMap to test for SQL Injection vulnerabilities.
- Command:
sqlmap -u "http://example.com/api?table=test" --risk=3 --level=5
By following these steps, users can mitigate the risk of SQL Injection in Apache Airflow MySQL Provider and secure their data.
