💻 Affected Systems
- Payroll Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive payroll data including employee information, salaries, and financial records.
If Mitigated
Limited data exposure if proper input validation and database permissions are enforced.
🎯 Exploit Status
Exploit details are publicly available and SQL injection is a well-understood attack vector.
🛠️ 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 software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize the 'bir' parameter and other user inputs.
Modify /add_deductions.php to include parameter validation using prepared statements or parameterized queries
Web Application Firewall
allDeploy WAF rules to block SQL injection attempts targeting /add_deductions.php.
Configure WAF to block requests containing SQL keywords in the 'bir' parameter
🧯 If You Can't Patch
- 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:
Test /add_deductions.php with SQL injection payloads in the 'bir' parameter and observe database errors or unexpected behavior.Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Attempt SQL injection after implementing fixes and confirm payloads are rejected without database errors.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts following SQL injection patterns
Network Indicators:
- HTTP requests to /add_deductions.php containing SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="/add_deductions.php" AND (param="bir" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "--")
