CVE-2024-9976
📋 TL;DR
This critical SQL injection vulnerability in Pharmacy Management System 1.0 allows attackers to execute arbitrary SQL commands via the 'text' parameter in the /php/manage_customer.php?action=search endpoint. Attackers can remotely exploit this to access, modify, or delete database contents. All users running the vulnerable version are affected.
💻 Affected Systems
- Pharmacy Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including theft of sensitive patient/medical data, deletion of critical pharmacy records, and potential system takeover via SQL injection leading to remote code execution.
Likely Case
Unauthorized access to patient records, prescription data, and pharmacy inventory information, potentially leading to data theft, manipulation, or destruction.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification privileges.
🎯 Exploit Status
Public exploit available via GitHub gist, requires no authentication, and uses simple SQL injection techniques
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative pharmacy management software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side input validation to sanitize the 'text' parameter before processing SQL queries
Modify /php/manage_customer.php to add parameter validation using prepared statements or input sanitization
Web Application Firewall Rules
allBlock SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: deny requests to /php/manage_customer.php?action=search containing SQL keywords in 'text' parameter
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls and monitor all traffic to the vulnerable endpoint
- Implement database-level protections: use least-privilege database accounts, enable SQL injection protection features, and implement comprehensive logging
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /php/manage_customer.php?action=search&text=1' OR '1'='1Check Version:
Check system documentation or about page for version informationVerify Fix Applied:
Attempt SQL injection tests and verify they are blocked or sanitized, check that prepared statements are implemented in the PHP code📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts or parameter manipulation in web server logs
- Requests to /php/manage_customer.php with SQL keywords in parameters
Network Indicators:
- HTTP requests containing SQL injection patterns (UNION, SELECT, OR 1=1) targeting the vulnerable endpoint
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/php/manage_customer.php" AND (param="text" AND value MATCHES "(?i)(union|select|or.*=.*|--|;)")
