CVE-2021-41554
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 · uneditedARCHIBUS 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

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedVersion 26 (or latest supported release)
- Contact ARCHIBUS support to obtain the upgrade package for version 26 or the latest supported release
- Review the official release notes and migration guide for version 26 to understand breaking changes and required configuration updates
- Create a full backup of the current database and configuration files
- Set up a staging environment to test the upgrade from version 21.3.3.815 to version 26
- Perform the upgrade in the staging environment and verify all custom workflows still function correctly
- Deploy the upgrade to production after successful staging validation
- After upgrade, verify that unauthenticated or non-admin users can no longer access the 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)
- Confirm that proper authorization checks are enforced on administrative functions
Generated from the published advisory — verify against the referenced sources before acting.
There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.
We develop and verify an original fix where the vendor hasn’t, from $1,950. Deployed to your staging first — never straight to production.
