  • Campcodes Payroll Management System
Versions: 1.0
Operating Systems: Any OS running PHP
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the specific version 1.0; other versions may also be vulnerable but not confirmed

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data theft, data destruction, or full system takeover via SQL injection to RCE chaining

🟠

Likely Case

Unauthorized access to sensitive payroll data including employee information, salaries, and financial records

🟢

If Mitigated

Limited impact with proper input validation and WAF rules blocking SQL injection patterns

🌐 Internet-Facing: HIGH - The vulnerability is remotely exploitable and public exploit exists
🏢 Internal Only: MEDIUM - Still significant risk if internal users can access the vulnerable endpoint

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploit details are publicly available on GitHub, making this easily weaponizable

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://www.campcodes.com/

Restart Required: No

Instructions:

No official patch available. Consider migrating to alternative payroll software or implementing workarounds.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation for the ID parameter in ajax.php

Modify ajax.php to validate ID parameter as integer: if(!is_numeric($_GET['ID'])) { die('Invalid input'); }

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns

Add WAF rule: SecRule ARGS:ID "@rx (?i)(union|select|insert|update|delete|drop|create|alter|exec)" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"

🧯 If You Can't Patch

  • Isolate the payroll system in a separate network segment with strict access controls
  • Implement database monitoring and alerting for unusual SQL queries

🔍 How to Verify

Check if Vulnerable:

Test the /ajax.php?action=save_payroll endpoint with SQL injection payloads like: ID=1' OR '1'='1

Check Version:

Check system documentation or about page for version information

Verify Fix Applied:

Test with same payloads and verify they are rejected or sanitized

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts or parameter manipulation in web server logs

Network Indicators:

  • HTTP requests to /ajax.php with SQL keywords in parameters
  • Unusual database traffic patterns

SIEM Query:

source="web_logs" AND uri="/ajax.php" AND (query="*union*" OR query="*select*" OR query="*insert*")
