CVE-2020-4762
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 Sterling B2B Integrator Standard Edition 5.2.0.0 through 5.2.6.5_2, 6.0.0.0 through 6.0.3.2, and 6.1.0.0 could allow an authenticated user to create a privileged account due to improper access controls. IBM X-Force ID: 188896.
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 Sterling B2B Integrator contains an improper access control vulnerability allowing authenticated users to create privileged (administrative) accounts. This is a vertical privilege escalation where standard users can bypass intended authorization checks to grant themselves elevated permissions.

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 Sterling B2B Integrator versionLocate the version file or use the administrative console to check the product version. Common paths include the installation directory or the system information page in the admin UI.Affected if The installed version falls within 5.2.0.0-5.2.6.5_2, 6.0.0.0-6.0.3.2, or equals 6.1.0.0
-
Verify access to user management moduleConfirm that standard (non-administrative) user accounts have access to the user creation or role assignment functionality in the admin console.Affected if Standard users can access or modify user roles or create new accounts without proper authorization checks
-
Review user accounts for unauthorized administrative rolesExport or list all user accounts in the system and identify any accounts with administrative privileges that were not created by known administrators.Affected if Administrative accounts exist that were not created through authorized administrator sessions
-
Examine audit and security logs for privilege escalation eventsSearch authentication and user management audit logs for events indicating standard users creating admin accounts, modifying roles, or accessing privileged functions.Affected if Logs show standard users performing privileged operations or creating administrator accounts
You are affected if your installed version matches the affected ranges AND standard authenticated users can create administrative accounts or elevate their own privileges.

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 dataApply IBM patches for this vulnerability. If no patch is available, implement compensating controls such as strict role-based access control enforcement in the user management module and monitoring for unauthorized privilege escalation attempts.
