CVE-2021-41554 — Archibus Web Central security vulnerability

High CVSS 8.8

ARCHIBUS Web Central 21.3.3.815 (a version from 2014) does not properly validate requests for access to data and functionality in these affected endpoints: /archibus/schema/ab-edit-users.axvw, /archibus/schema/ab-data-dictionary-table.axvw, /archibus/schema/ab-schema-add-field.axvw, /archibus/schema/ab-core/views/process-navigator/ab-my-user-profile.axvw. By not verifying the permissions for access to resources, it allows a potential attacker to view pages that are not allowed. Specifically, it was found that any authenticated user can reach the administrative console for user management by directly requesting access to the page via URL. This allows a malicious user to modify all users' profiles, to elevate any privileges to administrative ones, or to create or delete any type of user. It is also possible to modify the emails of other users, through a misconfiguration of the username parameter, on the user profile page. This is fixed in all recent versions, such as version 26. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Version 21.3 was officially de-supported by the end of 2020

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
