CVE-2025-5755
📋 TL;DR
This critical SQL injection vulnerability in SourceCodester Open Source Clinic Management System 1.0 allows attackers to manipulate database queries via the email parameter in /email_config.php. Attackers can remotely execute arbitrary SQL commands, potentially compromising sensitive medical data. All deployments of version 1.0 are affected.
💻 Affected Systems
- SourceCodester Open Source Clinic Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including patient medical records, authentication credentials, and system takeover leading to data breach, ransomware deployment, or system destruction.
Likely Case
Data exfiltration of sensitive patient information, credential theft, and potential lateral movement within the network.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
Public exploit code is available, making this easily weaponizable. No authentication required for exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative clinic management systems or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting /email_config.php
Input Validation
allImplement server-side validation to sanitize email parameter inputs
🧯 If You Can't Patch
- Immediately isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database access attempts
🔍 How to Verify
Check if Vulnerable:
Check if /email_config.php exists and accepts email parameter. Test with SQL injection payloads like ' OR '1'='1Check Version:
Check system version in admin panel or configuration filesVerify Fix Applied:
Verify parameterized queries are implemented and SQL injection attempts return errors instead of executing📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts after SQL injection
- Access to /email_config.php with suspicious parameters
Network Indicators:
- HTTP requests to /email_config.php containing SQL keywords (UNION, SELECT, INSERT, etc.)
- Unusual database traffic patterns
SIEM Query:
source="web_logs" AND uri="/email_config.php" AND (query CONTAINS "UNION" OR query CONTAINS "SELECT" OR query CONTAINS "INSERT")
