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
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the install blueprint declares only bp.before_request → @jwt_required() (app/routes/install/routes.py:36-39). The individual endpoints install_exporter, install_waf, install_geoip, check_geoip, get_exporter_version, and get_task_status are not wrapped in page_for_admin and do not call roxywi_common.is_user_has_access_to_its_group(server_ip) or check_is_server_in_group(server_ip). Only the GET index page (install_monitoring) gates on roxywi_auth.page_for_admin(level=2). Because the missing decorators omit both role and group checks, any logged-in user — including the default guest role 4 — can install/reconfigure exporters, WAF, and GeoIP databases on every server in the Roxy-WI database, regardless of tenant ownership. The Ansible playbooks run with the per-server SSH credential stored in Roxy-WI, which the credentials' rightful owner (a different tenant) has provisioned with sudo rights for the management workflow. At time of publication, there are no publicly available patches.

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 · high confidence

The install blueprint in Roxy-WI versions 8.2.6.4 and prior lacks function-level access controls on six endpoints (install_exporter, install_waf, install_geoip, check_geoip, get_exporter_version, get_task_status). These endpoints only have JWT authentication via bp.before_request but miss the page_for_admin decorator and group ownership validation functions (is_user_has_access_to_its_group, check_is_server_in_group), allowing any authenticated user including guest role 4 to execute Ansible playbooks that install/reconfigure exporters, WAF, and GeoIP databases on all servers regardless of tenant ownership.

MitigationApply the page_for_admin decorator with appropriate permission levels and implement group ownership validation functions on all install endpoints to enforce role-based and tenant-based access controls; network-segment management interfaces until patches are available.

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 Roxy-WI version
    Locate the Roxy-WI installation directory and check the version file or initial login page which typically displays the installed version number
    Affected if The installed version is 8.2.6.4 or any version prior to it
  2. Locate the install blueprint endpoints
    Inspect the Roxy-WI source code in the blueprints or routes directory for files containing the endpoints: install_exporter, install_waf, install_geoip, check_geoip, get_exporter_version, get_task_status
    Affected if These six endpoints exist in the codebase
  3. Verify decorator on vulnerable endpoints
    Open each of the six endpoint files and examine whether the page_for_admin decorator is applied to the route handler functions
    Affected if The page_for_admin decorator is absent from any of the six endpoints
  4. Check for group ownership validation
    Within each of the six endpoint functions, search for calls to is_user_has_access_to_its_group or check_is_server_in_group validation functions
    Affected if Neither validation function is called within these endpoint handlers
  5. Inspect JWT authentication configuration
    Examine the bp.before_request function in the install blueprint to confirm JWT token validation is the sole authentication mechanism
    Affected if JWT authentication is enabled but no role or permission checks occur after authentication
  6. Test guest role access
    Log in with a guest account (role 4) and attempt to access or trigger one of the six install endpoints via API call or web request
    Affected if A guest user can successfully access and execute operations on these endpoints

A user is affected if they run Roxy-WI version 8.2.6.4 or prior AND the install blueprint endpoints lack the page_for_admin decorator AND group ownership validation is not performed, allowing any authenticated user including guest role to execute sensitive install operations.

Mitigation

Apply the page_for_admin decorator with appropriate permission levels and implement group ownership validation functions on all install endpoints to enforce role-based and tenant-based access controls; network-segment management interfaces until patches are available.
