In short

Fortra GoAnywhere MFT has a flaw that lets attackers run commands on the server before logging in, by sending specially crafted data that tricks the software into executing malicious code. This is dangerous because anyone on the network can exploit it without needing a password.

Technical detail

The vulnerability exists in the License Response Servlet where untrusted serialized Java objects are deserialized without proper validation, allowing pre-authentication remote code execution. An unauthenticated attacker can exploit this by sending a malicious serialized object to execute arbitrary commands with the application's privileges. Patched in version 7.1.2.
