🔍 How to Verify
Check if Vulnerable:
Attempt to login with username: 'or'1'='1 and any password. If login succeeds, the system is vulnerable.Check Version:
Check the Part-DB version in the application footer or admin interface, or examine the source code version files.Verify Fix Applied:
Attempt the same SQL injection login after patching. Login should fail with proper authentication required.📡 Detection & Monitoring
Log Indicators:
- Login attempts containing SQL keywords like 'or', single quotes, or '1'='1' in username field
- Successful logins from unusual IP addresses or at unusual times
Network Indicators:
- HTTP POST requests to login.php with SQL injection patterns in parameters
SIEM Query:
source="partdb_logs" AND (message="*'or'*" OR message="*1'='1*") AND action="login"
