Complete database compromise including theft of sensitive banking data, account takeover, financial fraud, and potential destruction of all banking records.

🟠

Likely Case

Data exfiltration of user credentials and financial information, unauthorized account modifications, and potential privilege escalation.

🟢

If Mitigated

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

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploit details are publicly available on GitHub and vuldb.com. SQL injection via ID parameter is straightforward to exploit.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

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

Restart Required: No

Instructions:

No official patch available. Check vendor website for updates. Consider implementing parameterized queries or input validation as workaround.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Add input validation to ensure ID parameter contains only numeric values before processing.

Modify /removeuser.php to validate $_GET['ID'] or $_POST['ID'] is numeric using is_numeric() or similar function

Web Application Firewall (WAF) Rules

all

Implement WAF rules to block SQL injection patterns targeting the ID parameter.

Add WAF rule: Block requests to /removeuser.php containing SQL keywords in ID parameter

🧯 If You Can't Patch

  • Block external access to /removeuser.php using firewall rules or web server configuration
  • Implement network segmentation to isolate the banking system from sensitive networks

🔍 How to Verify

Check if Vulnerable:

Test /removeuser.php with SQL injection payloads like ' OR '1'='1 in the ID parameter and check for SQL errors or unexpected behavior.

Check Version:

Check application files or documentation for version information. No standard command available.

Verify Fix Applied:

Test with same SQL injection payloads and verify they are rejected or properly sanitized without executing SQL commands.

📡 Detection & Monitoring

Log Indicators:

  • SQL syntax errors in application logs
  • Unusual database queries from web server IP
  • Multiple failed attempts to /removeuser.php with malformed parameters

Network Indicators:

  • HTTP requests to /removeuser.php containing SQL keywords (SELECT, UNION, etc.) in parameters
  • Unusual database traffic patterns from web server

SIEM Query:

source="web_logs" AND uri="/removeuser.php" AND (param="*SELECT*" OR param="*UNION*" OR param="*OR*1*" OR param="*--*" OR param="*;*" OR param="*'*")
