📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database takeover allowing data theft, modification, or deletion; potential remote code execution if database functions permit; full system compromise.

🟠

Likely Case

Unauthorized access to sensitive homeowner data including personal information, financial records, and collection details; database manipulation or destruction.

🟢

If Mitigated

Limited impact with proper input validation and parameterized queries; potential for error messages revealing database structure but no data compromise.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Public proof-of-concept available on GitHub; SQL injection via GET parameter is straightforward to exploit

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None known

Restart Required: No

Instructions:

No official patch available. Implement parameterized queries in Master.php delete_phase function and validate all user inputs.

🔧 Temporary Workarounds

Web Application Firewall (WAF)

all

Deploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint

Input Validation Filter

all

Add input validation to sanitize parameters before processing in Master.php

🧯 If You Can't Patch

  • Block external access to /hocms/classes/Master.php endpoint at network firewall level
  • Implement strict database user permissions with least privilege principle

🔍 How to Verify

Check if Vulnerable:

Test the endpoint with SQL injection payloads: /hocms/classes/Master.php?f=delete_phase&id=1' OR '1'='1

Check Version:

Check application version in admin panel or configuration files

Verify Fix Applied:

Verify that parameterized queries are implemented and SQL injection payloads no longer work

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in application logs
  • Multiple requests to Master.php with SQL syntax in parameters
  • Database error logs showing unexpected queries

Network Indicators:

  • HTTP requests containing SQL keywords (SELECT, UNION, etc.) to the vulnerable endpoint
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND uri="/hocms/classes/Master.php" AND (query="*SELECT*" OR query="*UNION*" OR query="*OR*1*" OR query="*'--*" OR query="*;--*")
