How to detect it

Nuclei template (active check)

Goanywhere - Command Injection

A deserialization vulnerability in the License Servlet of Fortra’s GoAnywhere MFT allows an actor with a validly forged license response signature to deserialize an arbitrary actor-controlled object, possibly leading to command injection.

Name and description quoted from the template, written by VEDAS.

The template sends 2 requests (GET /goanywhere/license/Unlicensed.xhtml/{{string}}?javax.faces.ViewSta..., GET /license/Unlicensed.xhtml/{{string}}?javax.faces.ViewState={{string...); it decides using dsl matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
