✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Implement File Upload Validation
allAdd server-side validation for file uploads to restrict file types, extensions, and content.
Modify pages_view_client.php to validate file extensions and MIME types before processing
Web Application Firewall Rules
allBlock requests containing suspicious file upload patterns to the vulnerable endpoint.
WAF rule: Block POST requests to */pages_view_client.php containing executable file extensions in profile_pic parameter
🧯 If You Can't Patch
- Isolate the affected system from critical networks and implement strict network segmentation.
- Implement additional authentication controls and monitor for suspicious file upload activities.
🔍 How to Verify
Check if Vulnerable:
Test if you can upload a file with executable extension (e.g., .php, .jsp) through the profile_pic parameter in pages_view_client.php.Check Version:
Check application version in admin panel or configuration files for 'Code Astro Internet Banking System 2.0.0'Verify Fix Applied:
Attempt the same file upload test after implementing fixes; successful uploads of executable files should be blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to pages_view_client.php
- Files with executable extensions in upload directories
- Multiple failed upload attempts
Network Indicators:
- POST requests to pages_view_client.php with file uploads
- Outbound connections from web server to unknown IPs
SIEM Query:
source="web_logs" AND uri="*pages_view_client.php*" AND method="POST" AND (file_extension="php" OR file_extension="jsp" OR file_extension="exe")
