Complete database compromise including data theft, data destruction, authentication bypass, and potential remote code execution via database functions.

🟠

Likely Case

Unauthorized data access, message manipulation, user information theft, and potential privilege escalation within the chat system.

🟢

If Mitigated

Limited impact with proper input validation and database permissions, potentially only error messages or minimal data exposure.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploit code is publicly available on GitHub. SQL injection via msg parameter is straightforward.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://code-projects.org/

Restart Required: No

Instructions:

1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with supported software.

🔧 Temporary Workarounds

Input Validation Filter

all

Add parameterized queries and input validation to /user/send_message.php

Modify PHP code to use prepared statements: $stmt = $conn->prepare('INSERT INTO messages (msg) VALUES (?)'); $stmt->bind_param('s', $msg);

Web Application Firewall

all

Deploy WAF with SQL injection rules to block malicious requests

🧯 If You Can't Patch

  • Block external access to /user/send_message.php via firewall rules
  • Implement database user with minimal permissions (read-only if possible)

🔍 How to Verify

Check if Vulnerable:

Test /user/send_message.php with SQL injection payloads like: msg=test' OR '1'='1

Check Version:

Check software documentation or about page for version information

Verify Fix Applied:

Test with same payloads - should return error or no database interaction

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL errors in application logs
  • Multiple failed message submissions with SQL syntax
  • Requests to /user/send_message.php with SQL keywords

Network Indicators:

  • POST requests to /user/send_message.php containing SQL injection patterns
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND uri_path="/user/send_message.php" AND (msg="*' OR*" OR msg="*UNION*" OR msg="*SELECT*" OR msg="*INSERT*")
