Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Authentication bypass in the 2FA feature in Devolutions Server 2024.1.14.0 and earlier allows an authenticated attacker to authenticate to another user without being asked for the 2FA via another browser tab.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Authentication bypass in the 2FA feature allows an authenticated attacker to bypass 2FA requirements when authenticating to another user by leveraging another browser tab. The vulnerability appears to stem from improper session or state management where the 2FA challenge is not consistently enforced across concurrent sessions.

MitigationUpgrade Devolutions Server to a version newer than 2024.1.14.0. Until then, monitor authentication logs for suspicious concurrent session activity and consider implementing additional session coordination controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Devolutions Server version
    Check the installed version of Devolutions Server. This is typically available in the Server Manager console under 'About' or in the installation directory readme/release notes. On the server, you can also check the installed programs list or the Devolutions Server management interface.
    Affected if The version is lower than 2024.1.15.0
  2. Verify if 2FA is enabled
    In Devolutions Server management console, navigate to User Management or Authentication settings to check if Two-Factor Authentication (2FA) is configured and enforced for users.
    Affected if 2FA is enabled and enforced in the environment
  3. Review authentication logs for concurrent session anomalies
    Examine Devolutions Server authentication logs for entries showing multiple concurrent authentication attempts or sessions for different users from the same source IP or browser within tight time windows, which could indicate exploitation attempts.
    Affected if Logs show suspicious concurrent session patterns that suggest 2FA bypass attempts

The environment is affected if Devolutions Server version is below 2024.1.15.0 AND 2FA is enabled, as this is the only scenario where the 2FA bypass vulnerability can be exploited.

Upgrade available Upgrade to 2024.1.15.0 or later
Fixed in 2024.1.15.0
Interim mitigation

Upgrade Devolutions Server to a version newer than 2024.1.14.0. Until then, monitor authentication logs for suspicious concurrent session activity and consider implementing additional session coordination controls.

Recommended fix High confidence

2024.1.15.0

  1. 1. Backup your current Devolutions Server database and configuration.
  2. 2. Verify current installed version by checking About or system information in Devolutions Server.
  3. 3. Download Devolutions Server version 2024.1.15.0 or later from the official Devolutions download page.
  4. 4. Apply the update following standard Devolutions Server upgrade procedures.
  5. 5. Verify the update was successful and the 2FA authentication flow now properly enforces 2FA across browser tabs.
  6. 6. Test that 2FA authentication works correctly for all users after the upgrade.
