Technical Analysis

Based on the technical writeup and PoC from Horizion3, this vulnerability can be exploited by an unauthenticated attacker with access to the management interface of GoAnywhere MFT (by default the management interface is available over TCP port 8000 for HTTP and TCP port 8001 for HTTPS), to create a new administrator account on the system. The attacker value is rated as very high given this product is a file transfer solution, and has been targeted by ransomware groups such a Cl0p in the past. I rated the exploitability as high given the management interface must be exposed for exploitation to succeed, which it may not be in all environments.

The vulnerabilities lies in the endpoint /goanywhere/wizard/InitialAccountSetup.xhtml. This endpoint is used during the products initial setup, to create the first administrator user. After setup has completed, this endpoint is no longer available. However using a Tomcat path traversal technique of inserting the path segment ..;, allows the endpoint to be reached successfully via the path /goanywhere/images/..;/wizard/InitialAccountSetup.xhtml. A HTTP POST request can then be made by an unauthenticated attacker to create a new administrator account with a password of the attackers choosing.
