**Name of the Vulnerable Software and Affected Versions**
ARCHIBUS Web Central version 21.3.3.815
**Description**
The issue arises from the software's failure to properly validate requests for access to data and functionality in several affected endpoints: "/archibus/schema/ab-edit-users.axvw", "/archibus/schema/ab-data-dictionary-table.axvw", "/archibus/schema/ab-schema-add-field.axvw", and "/archibus/schema/ab-core/views/process-navigator/ab-my-user-profile.axvw". This allows any authenticated user to access pages not intended for them, including the administrative console for user management, by directly requesting access via URL. A malicious user can exploit this to modify all users' profiles, elevate privileges to administrative levels, create or delete any type of user, and even modify other users' emails through a misconfiguration of the `username` parameter on the user profile page.
**Recommendations**
For version 21.3.3.815, consider upgrading to a recent version, such as version 26, to fix the issue. As a temporary workaround, restrict access to the administrative console and limit modifications to user profiles until an upgrade can be performed. Additionally, review and correct any misconfigurations of the `username` parameter to prevent unauthorized email modifications.
