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
Incorrect permission management in Devolutions Server before 2022.2 allows a new user with a preexisting username to inherit the permissions of that previous user.

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

In Devolutions Server versions before 2022.2, when a user account is deleted and a new account is created with the same username, the new account incorrectly inherits all permissions, roles, and access rights assigned to the previous account. This permission inheritance occurs due to improper handling of username reuse in the user management backend, allowing a new user to gain unintended elevated privileges.

MitigationUpgrade Devolutions Server to version 2022.2 or later, which contains the fix for proper permission management. Audit existing user accounts for any that may have been created with reused usernames to verify permissions are correctly scoped.

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. Check Devolutions Server version
    Locate the installed version of Devolutions Server through the administration console, About section, or installation directory version file
    Affected if Version is before 2022.2.0
  2. Review user account audit logs
    Examine user management logs or audit trails for instances where a user account was deleted and a new account was created with the identical username
    Affected if Any such username reuse events exist in the logs
  3. Inspect permissions on reused username accounts
    For accounts identified with reused usernames, compare their assigned roles, permissions, and access rights against what would be expected for a newly created account
    Affected if Permissions exceed default new user permissions or match the previous account's permissions

Your environment is affected if you run Devolutions Server version before 2022.2 and you have any user accounts that were created with usernames previously assigned to deleted accounts.

Generated from the published advisory. Verify against your own configuration.

Upgrade available Upgrade to 2022.2.0 or later
Fixed in 2022.2.0
Interim mitigation

Upgrade Devolutions Server to version 2022.2 or later, which contains the fix for proper permission management. Audit existing user accounts for any that may have been created with reused usernames to verify permissions are correctly scoped.

Recommended fix High confidence

2022.2.0

  1. Backup the Devolutions Server database before starting the upgrade process
  2. Download Devolutions Server version 2022.2.0 or later from the official Devolutions website
  3. Stop the Devolutions Server service
  4. Run the installer/upgrade package for version 2022.2.0 or later
  5. Follow the installation wizard prompts to complete the upgrade
  6. Start the Devolutions Server service
  7. Verify the upgrade was successful by checking the server version
  8. Test that newly created users with previously existing usernames do NOT inherit permissions from deleted users with the same name
