CVE-2024-6903
📋 TL;DR
This critical SQL injection vulnerability in SourceCodester Record Management System 1.0 allows remote attackers to execute arbitrary SQL commands via the 'position' parameter in sort1_user.php. Attackers can potentially read, modify, or delete database contents, including sensitive user records. All deployments of version 1.0 with the vulnerable file accessible are affected.
💻 Affected Systems
- SourceCodester Record Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access and exfiltration of sensitive records, potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permission restrictions in place.
🎯 Exploit Status
Public exploit code is available on GitHub. SQL injection via URL parameter manipulation is straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Consider migrating to a supported alternative or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the 'position' parameter before processing
Modify sort1_user.php to validate/sanitize input using prepared statements
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection attempts targeting the vulnerable parameter
Add WAF rule: Block requests containing SQL keywords in position parameter
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules
- Implement database user with minimal permissions (read-only if possible)
🔍 How to Verify
Check if Vulnerable:
Test by sending SQL injection payloads to the position parameter in sort1_user.php requestsCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return appropriate error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web logs
- Multiple failed login attempts following SQL payloads
- Requests to sort1_user.php with suspicious position parameter values
Network Indicators:
- SQL keywords (UNION, SELECT, INSERT) in URL parameters
- Abnormal database query patterns from web server
SIEM Query:
web_access_logs | where url contains "sort1_user.php" and (url contains "UNION" or url contains "SELECT" or url contains "INSERT" or url contains "--" or url contains "' OR ")🔗 References
