CVE-2025-3871

Broken Access Control Leads to Limited Denial of Service in GoAnywhere MFT 7.8.0 and earlier

Description

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.

Remediation

Solution:

  • Upgrade to GoAnwhere MFT 7.8.1 or higher

Workaround:

  • * Ensure all users configured to use GOTP email for 2FA already have an email set. * In situations where the email cannot be set ahead of time (ex: Self-Registration), switch Admin and Web User Templates to use another 2FA option such as Time-based One-Time Password or RADIUS.
