CVE-2019-25473
📋 TL;DR
Clinic Pro software contains a SQL injection vulnerability in the monthly_expense_overview endpoint's month parameter. Authenticated attackers can inject SQL code to extract sensitive database information using blind or error-based techniques. This affects Clinic Pro installations with vulnerable versions exposed to authenticated users.
💻 Affected Systems
- Clinic Pro
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including patient records, financial data, credentials, and potential system takeover via privilege escalation.
Likely Case
Extraction of sensitive patient data, financial records, and user credentials leading to data breach and compliance violations.
If Mitigated
Limited impact with proper input validation and database permissions restricting data access.
🎯 Exploit Status
Exploit code available on Exploit-DB, requires authentication but SQL injection techniques are well-documented and automated tools exist.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Specific version not documented in public references
Vendor Advisory: Not provided in references
Restart Required: Yes
Instructions:
1. Contact Clinic Pro vendor for patched version
2. Backup database and application
3. Apply vendor-provided patch
4. Restart application services
5. Verify fix with testing
🔧 Temporary Workarounds
Input Validation WAF Rule
allImplement web application firewall rules to block SQL injection patterns in month parameter
WAF-specific configuration commands vary by platform
Parameterized Query Implementation
allModify application code to use parameterized queries instead of string concatenation
Code modification required - implement prepared statements for database queries
🧯 If You Can't Patch
- Implement strict input validation to only accept valid month formats (01-12)
- Apply database principle of least privilege - restrict application database user permissions
🔍 How to Verify
Check if Vulnerable:
Test with SQL injection payloads in month parameter: ' OR '1'='1 or time-based payloads like '; WAITFOR DELAY '00:00:05'--Check Version:
Check Clinic Pro version through admin interface or application filesVerify Fix Applied:
Attempt SQL injection tests after patch - should return error or no data extraction📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple POST requests to monthly_expense_overview with unusual month values
- Database queries with SQL keywords from application layer
Network Indicators:
- POST requests to /monthly_expense_overview with SQL injection patterns in parameters
- Unusual database response times indicating time-based blind SQLi
SIEM Query:
source="web_logs" AND uri="/monthly_expense_overview" AND (param="month" AND value MATCH "('|;|--|UNION|SELECT|WAITFOR)")
