Executive Summary

This vulnerability is an improper authentication issue in the two-factor authentication (2FA) feature of Devolutions Server version 2026.1.11 and earlier. It allows a remote attacker who already has valid credentials to bypass the multifactor authentication process by reusing a partially authenticated session token, thereby gaining unauthorized access to the victim's account.

Impact Analysis

The impact of this vulnerability is that an attacker with valid credentials can bypass the additional security layer provided by two-factor authentication. This means the attacker can gain unauthorized access to user accounts, potentially leading to data breaches, unauthorized actions, and compromise of sensitive information.
