📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data theft, privilege escalation to admin, and potential remote code execution via database functions.

🟠

Likely Case

Unauthorized data extraction from the database, including user credentials, sensitive content, and configuration data.

🟢

If Mitigated

Limited impact with proper input validation and parameterized queries preventing successful exploitation.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires admin access to the /admin/add_sidebar.php endpoint, but SQL injection payloads are straightforward and well-documented.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None available

Restart Required: No

Instructions:

1. Review the vulnerable code in /admin/add_sidebar.php
2. Replace direct SQL concatenation with parameterized queries
3. Implement proper input validation and sanitization
4. Test the fix thoroughly before deployment

🔧 Temporary Workarounds

Input Validation Filter

all

Add server-side validation to reject malicious SQL characters in input fields

# In PHP, add before SQL execution:
$input = preg_replace('/[^a-zA-Z0-9_\-\s]/', '', $_POST['input_field']);

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns

# Example ModSecurity rule:
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"

🧯 If You Can't Patch

  • Restrict access to /admin/add_sidebar.php endpoint using IP whitelisting or authentication requirements
  • Implement database-level protections such as least privilege accounts and query logging

🔍 How to Verify

Check if Vulnerable:

Test the /admin/add_sidebar.php endpoint with SQL injection payloads like ' OR '1'='1 in input parameters

Check Version:

Check EliteCMS version in configuration files or admin panel

Verify Fix Applied:

Attempt SQL injection attacks against the patched endpoint and verify they are blocked or sanitized

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in application logs
  • Multiple failed login attempts followed by admin access
  • Suspicious POST requests to /admin/add_sidebar.php with SQL keywords

Network Indicators:

  • HTTP requests containing SQL injection patterns to the vulnerable endpoint
  • Unusual database query patterns from the application server

SIEM Query:

source="web_logs" AND uri="/admin/add_sidebar.php" AND (request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%" OR request_body LIKE "%OR%1%1%")
