Instructions:
No official patch is available. Consider the workarounds below or replace the software entirely.
🔧 Temporary Workarounds
Disable File Upload Feature
allRemove or disable the vulnerable file upload functionality in the dashboard services module.
# Locate and modify /dashboard/Services.php to remove file upload handling
# Alternatively, restrict access to the entire dashboard directory
Implement File Upload Restrictions
allAdd server-side validation to restrict file types, extensions, and implement proper sanitization.
# Add file type validation in PHP: check mime types and extensions
# Implement file size limits and scanning for malicious content
🧯 If You Can't Patch
- Implement a web application firewall (WAF) with rules to block malicious file uploads and suspicious requests to the vulnerable endpoint.
- Restrict network access to the CMS dashboard using IP whitelisting, ensuring only authorized administrators can access the vulnerable functionality.
🔍 How to Verify
Check if Vulnerable:
Check if you have SourceCodester Company Website CMS version 1.0 installed. Attempt to upload a test file to /dashboard/Services endpoint without authentication.
Check Version:
# Check CMS version in admin panel or look for version files in installation directory
Verify Fix Applied:
Test that file uploads to the vulnerable endpoint are now properly restricted or blocked, and authentication is required for dashboard access.
