CVE-2025-36440
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 · uneditedIBM Concert 1.0.0 through 2.2.0 could allow a local user to obtain sensitive information due to missing function level access control.
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 confidenceIBM Concert versions 1.0.0 through 2.2.0 contains a missing function-level access control vulnerability that allows local authenticated users to access sensitive information they should not have permission to view. The vulnerability stems from improper authorization checks at the function or API endpoint level, enabling privilege escalation through direct access to restricted functions.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed IBM Concert versionRun 'ibmconcert --version' or check the product documentation for the installed version location (typically in /opt/ibm/concert or the installation directory)Affected if The installed version falls within 1.0.0 through 2.2.0 (inclusive)
-
Review user role configurationExamine the user management or role-based access control (RBAC) configuration files to identify defined roles and their assigned permissionsAffected if Users with lower-privilege roles can access functions or data intended for higher-privilege roles
-
Inspect sensitive function or API endpoint access controlsReview the access control settings for sensitive functions or API endpoints - look for authorization checks in the configuration or application code that governs who can call specific functionsAffected if Sensitive functions or API endpoints lack proper authorization validation or allow unrestricted access based on user role
-
Test function-level access by creating test users with different rolesIf possible, create users with limited roles and attempt to access functions that should be restricted to higher-privilege users - document any successful unauthorized accessAffected if A lower-privileged authenticated user can access sensitive functions or information they should not be authorized to view
If the installed IBM Concert version is between 1.0.0 and 2.2.0 and sensitive functions or API endpoints lack proper role-based authorization checks allowing lower-privileged users to access restricted functionality, the environment is affected.

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.
From vendor dataImplement proper function-level access control checks to ensure users can only access functions and data appropriate to their authorization level. Review and restrict sensitive function endpoints to authorized roles only.
