"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.");
