"According to its self-reported version, the instance of Fortra GoAnywhere Managed File Transfer (MFT) running on the
remote web server is prior to 7.8.1. It is, therefore, affected by a broken access Control vulnerability:

  - Broken access control in Fortra's GoAnywhere MFT prior to 7.8.1 allows an attacker to create a denial of 
    service situation when configured to use GoAnywhere One-Time Password (GOTP) email two-factor 
    authentication (2FA) and the user has not set an email address. In this scenario, the attacker may enter 
    the email address of a known user when prompted and the user will be disabled if that user has configured 
    GOTP. (CVE-2025-3871)
 
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
