Vulnerability Description
An issue has been identified in the file upload mechanism where insufficient validation of file types allows attackers to upload malicious scripts (such as PHP, Node.js scripts, or shell files). If these files are uploaded to a publicly accessible directory and executed, it could lead to full server compromise.
Impact
This is a severe vulnerability. An attacker can execute arbitrary commands on the server, compromising the entire backend infrastructure, accessing sensitive database credentials, and potentially pivoting to other internal systems.
Remediation Steps
- Implement strict allow-listing for file extensions and MIME types.
- Validate file contents (e.g., using magic numbers) to ensure they match the extension.
- Store uploaded files in a dedicated sandboxed storage bucket (like AWS S3 or Supabase Storage) rather than local server directories.
- Strip execution permissions from uploaded files.
