Synopsis

The Devolutions Server instance installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Devolutions Server installed on the remote host is prior to 2025.2.17.0, or 2025.3.x prior to 2025.3.6.0, and is, therefore, affected by multiple vulnerabilities:

 - Improper privilege management during pre-MFA cookie handling in Devolutions Server allows a low-privileged authenticated user to impersonate another account by replaying the pre-MFA cookie.This does not bypass the target account MFA verification step. This issue affects the following versions : * Devolutions Server 2025.3.2.0 through 2025.3.5.0 * Devolutions Server 2025.2.15.0 and earlier. (CVE-2025-12485)

 - Improper access control in Devolutions allows a View-only user to retrieve sensitive third-level nested fields, such as password lists custom values, resulting in password disclosure. This issue affects the following versions : * Devolutions Server 2025.3.2.0 through 2025.3.5.0 * Devolutions Server 2025.2.15.0 and earlier. (CVE-2025-12808)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Devolutions Server version 2025.2.17.0 or 2025.3.6.0 or later.
