💻 Affected Systems
- MD-MAFUJUL-HASAN Online Payroll Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, or remote code execution if database permissions allow.
Likely Case
Unauthorized data access including sensitive payroll information, employee records, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permission restrictions in place.
🎯 Exploit Status
Exploit has been publicly disclosed and requires minimal technical skill to execute. No authentication required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None - vendor did not respond to disclosure
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative payroll software or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting /designation_viewmore.php
# Example ModSecurity rule: SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"
# Add to WAF configuration to block suspicious id parameter patterns
Input Validation Filter
allAdd server-side validation to restrict id parameter to expected numeric values only
# PHP example: if(!is_numeric($_GET['id']) || $_GET['id'] <= 0) { die('Invalid input'); }
# Add to designation_viewmore.php before SQL query execution
🧯 If You Can't Patch
- Isolate the payroll system in a separate network segment with strict access controls
- Implement database-level protections: restrict application database user permissions to minimum required
🔍 How to Verify
Check if Vulnerable:
Test /designation_viewmore.php?id=1' OR '1'='1 and observe if SQL error or unexpected behavior occursCheck Version:
Check application files or database for version markers. No standard command available for this custom application.Verify Fix Applied:
Test with SQL injection payloads and verify they are rejected or properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple rapid requests to /designation_viewmore.php with varying id parameters
- Requests containing SQL keywords like UNION, SELECT, OR in id parameter
Network Indicators:
- Unusual database traffic patterns from web server
- HTTP requests with SQL injection patterns in URL parameters
SIEM Query:
web.url:"*/designation_viewmore.php*" AND (web.param.id:"*'*" OR web.param.id:"*UNION*" OR web.param.id:"*SELECT*" OR web.param.id:"*OR*" OR web.param.id:"*--*")🔗 References
