DescriptionCVE.org

Improper enforcement of the Disable password saving in vaults setting in the connection entry component in Devolutions Remote Desktop Manager 2025.3.30 and earlier allows an authenticated user to persist credentials in vault entries, potentially exposing sensitive information to other users, by creating or editing certain connection types while password saving is disabled.

Executive ViewAI

Why It Matters

A critical vulnerability in Devolutions Remote Desktop Manager allows authenticated users to bypass password vault security controls and expose stored credentials to other system users. This threatens credential confidentiality across the organization and could enable lateral movement and unauthorized access to critical systems.

Business Impact: Severe

Compensating Controls

Disable user permissions to create or edit connection entries in Remote Desktop Manager until patch availability; implement application-level access controls restricting vault access to named administrators; segment Remote Desktop Manager infrastructure on isolated network; enforce multi-factor authentication for all vault access; monitor and log all connection entry modifications; consider temporary migration to alternative credential management solutions for sensitive credentials.
