How the Exploit Works
The exploit takes advantage of an improper access control issue in the Workflow component of Fortra’s FileCatalyst. More specifically, the order forms page does not adequately verify the authenticity of file uploads. This allows an attacker to upload arbitrary and potentially malicious files to the system. These files could contain malware or scripts designed to compromise the system or exfiltrate sensitive data.
Conceptual Example Code
Below is a conceptual example of how an attacker might exploit this vulnerability. It demonstrates an HTTP POST request with a malicious payload being uploaded to the order forms page.
POST /orderforms/upload HTTP/1.1
Host: target.example.com
Content-Type: application/octet-stream
Content-Length: [length of the payload]
{ "malicious_file": "..." }In this example, `{ “malicious_file”: “…” }` represents the malicious payload-an arbitrary file that the attacker seeks to upload. The server does not require authentication for this action, meaning that any individual with network access to the target system can exploit this vulnerability.
Mitigation
The most effective mitigation for this vulnerability is to apply the vendor’s patch. Fortra has released an update that resolves the improper access control issue in the Workflow component of FileCatalyst. Until you can apply this patch, a potential temporary mitigation would involve implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and filter out malicious traffic. However, this only serves as a temporary solution and does not eliminate the vulnerability. As such, it is highly recommended to apply the vendor’s patch as soon as feasibly possible.
