CVE-2025-3871

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

Published Jul 16, 2025 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
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

Vendor Solution

Upgrade to GoAnwhere MFT 7.8.1 or higher


Vendor 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.
