🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://itsourcecode.com/

Restart Required: No

Instructions:

No official patch available. Consider upgrading to a newer version if available or implementing workarounds.

🔧 Temporary Workarounds

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns in login requests.

# Example ModSecurity rule: SecRule ARGS:Username "@detectSQLi" "id:1001,phase:2,deny,status:403"

Input Validation Filter

all

Add server-side input validation to sanitize Username parameter before processing.

# PHP example: $username = mysqli_real_escape_string($conn, $_POST['Username']);

🧯 If You Can't Patch

  • Isolate the system from internet access and restrict to internal network only.
  • Implement strict network segmentation and monitor all traffic to /ajax.php?action=login endpoint.

🔍 How to Verify

Check if Vulnerable:

Test the /ajax.php?action=login endpoint with SQL injection payloads in Username parameter (e.g., admin' OR '1'='1).

Check Version:

Check software version in admin panel or readme files. Default installation is version 1.0.

Verify Fix Applied:

Verify that SQL injection attempts return error messages or are blocked without executing.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL syntax in Username parameter
  • Multiple failed login attempts with SQL characters
  • Database error messages in application logs

Network Indicators:

  • HTTP POST requests to /ajax.php?action=login with SQL keywords in parameters
  • Unusual traffic patterns to login endpoint

SIEM Query:

source="web_logs" AND uri="/ajax.php" AND query="action=login" AND (Username="*'*" OR Username="*OR*" OR Username="*UNION*" OR Username="*SELECT*")
