📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise, including data exfiltration, deletion, or unauthorized administrative access leading to full system takeover.
Likely Case
Unauthorized access to sensitive employee and visitor data, potential data manipulation, and privilege escalation within the application.
If Mitigated
Limited impact if proper input validation and SQL injection protections are in place, though the vulnerability remains exploitable.
🎯 Exploit Status

🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch is available from the vendor. Consider applying custom fixes or workarounds, such as input validation and parameterized queries, or discontinuing use of the software.
🔧 Temporary Workarounds
Implement Input Validation and Parameterized Queries
allModify the Master.php file to sanitize the 'id' parameter and use prepared statements to prevent SQL injection.
Edit /employee_gatepass/classes/Master.php to replace raw SQL queries with parameterized queries using PDO or MySQLi.
Restrict Access to Vulnerable Endpoint
linuxUse web server configuration (e.g., .htaccess for Apache) to block or restrict access to the /employee_gatepass/classes/Master.php file.
Add 'Deny from all' in .htaccess for the specific directory or use firewall rules to block the endpoint.
🧯 If You Can't Patch
- Isolate the system from the internet and restrict network access to authorized users only.
- Implement a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts targeting the vulnerable endpoint.
🔍 How to Verify
Check if Vulnerable:
Test the endpoint /employee_gatepass/classes/Master.php?f=delete_department with a malicious SQL payload (e.g., id=1' OR '1'='1) and check for error responses or unexpected behavior.Check Version:
Check the software version in the application's documentation or configuration files; no standard command is available.Verify Fix Applied:
After applying workarounds, retest with the same payload to ensure no SQL errors or unauthorized data access occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs (e.g., PHP warnings related to MySQL queries) for the Master.php endpoint.
- Multiple rapid requests to /employee_gatepass/classes/Master.php with varying 'id' parameters.
Network Indicators:
- HTTP requests containing SQL keywords (e.g., SELECT, UNION, DROP) in the query string for the vulnerable endpoint.
SIEM Query:
source="web_server_logs" AND url="/employee_gatepass/classes/Master.php" AND (query_string="*id=*'*" OR query_string="*id=*%27*")
