📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to theft of all payroll data, financial information, employee PII, and potential system takeover via SQL injection to RCE escalation.
Likely Case
Data exfiltration of sensitive payroll information, employee records, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation, parameterized queries, and WAF protection blocking malicious SQL payloads.
🎯 Exploit Status
Exploit code is publicly available on GitHub. Remote exploitation requires no authentication. Simple SQL injection via URL parameter manipulation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor was contacted but did not respond. Consider migrating to alternative payroll software.
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the /shift_viewmore.php endpoint
# Example ModSecurity rule: SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny,status:403"
Input Validation Filter
allAdd server-side validation to only accept numeric values for the 'id' parameter
# PHP example: if(!is_numeric($_GET['id'])) { die('Invalid input'); }
🧯 If You Can't Patch
- Network segmentation: Isolate the payroll system from internet access and restrict to internal trusted networks only
- Implement strict access controls and monitor all database queries from the application
🔍 How to Verify
Check if Vulnerable:
Test by accessing /shift_viewmore.php?id=1' OR '1'='1 and observing if SQL error appears or unexpected data returnsCheck Version:
Check application files for version indicators or last modified dates of /shift_viewmore.phpVerify Fix Applied:
Verify that SQL injection attempts return proper error messages or are blocked, and that only numeric IDs are accepted📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application user
- Multiple rapid requests to /shift_viewmore.php with varying id parameters
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in URL parameters
- Abnormal traffic patterns to the payroll system
SIEM Query:
source="web_logs" AND (url="/shift_viewmore.php" AND (query="*id=*'*" OR query="*id=*%27*" OR query="*id=*SELECT*" OR query="*id=*UNION*"))🔗 References
