⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of medical database including patient health records, financial data, and system credentials, potentially leading to data destruction, ransomware deployment, or medical identity theft.
Likely Case
Data exfiltration of sensitive patient information (PII/PHI), modification of medical records, and potential system disruption affecting patient care operations.
If Mitigated
Limited impact with proper network segmentation, WAF protection, and database access controls preventing successful exploitation.
🎯 Exploit Status
SQL injection vulnerabilities are commonly weaponized; unauthenticated access makes exploitation trivial for attackers with basic SQL knowledge
