Attack Vector
This vulnerability is exploitable via network by sending crafted HTTP or HTTPS requests.
SELECT * FROM users WHERE username = 'admin' OR '1'='1';
Detection Methods for CVE-2025-25257
Indicators of Compromise
- Unusual database queries or data access logs
- Erroneous application server logs indicating failed queries
- Unexplained changes in database records
Detection Strategies
Monitoring for unexpected SQL queries or anomalies in query logs can identify potential exploitation. Utilize WAF to detect and block SQL patterns that deviate from the norm.
Monitoring Recommendations
Employ real-time database monitoring tools to track and alert unusual query activity. Implement and maintain WAF rules to prevent malicious SQL input.
