CVE-2020-4657
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 5.2.0.0 through 6.0.3.2 Standard Edition is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 186094.
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 · high confidenceStored cross-site scripting (XSS) vulnerability in IBM Sterling B2B Integrator Web UI versions 5.2.0.0 through 6.0.3.2 allows authenticated users to inject malicious JavaScript code that executes in browsers of other users viewing the affected interface, potentially leading to session hijacking and credentials disclosure.

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.
-
Check installed IBM Sterling B2B Integrator versionLocate the version information for your IBM Sterling B2B Integrator installation (typically accessible via the product's about page, installation directory, or admin console) and compare it against the affected range 5.2.0.0 through 6.0.3.2Affected if Your installed version falls within 5.2.0.0 to 6.0.3.2 inclusive
-
Verify Web UI component is exposedConfirm that the IBM Sterling B2B Integrator Web UI interface is accessible and enabled in your environment (check web server configuration, port bindings, or admin settings)Affected if The Web UI is accessible and you are running an affected version
-
Confirm user authentication is enabled for Web UIReview your Web UI authentication settings to verify that user authentication is required for access (the XSS requires authenticated users to inject the payload)Affected if Web UI authentication is enabled and you are running an affected version
-
Audit Web UI user input fields for potential XSS injection pointsInspect the Web UI configuration and logs for any unexpected or malicious script tags, JavaScript event handlers, or encoded payloads in user-supplied fields such as names, descriptions, or custom labelsAffected if Suspicious script content is found in user-accessible fields of the Web UI
You are affected if your IBM Sterling B2B Integrator version is between 5.2.0.0 and 6.0.3.2 inclusive AND the Web UI component is enabled and accessible to authenticated users.

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 security patch or upgrade to version 6.0.3.3 or later. As a temporary measure, implement strict input validation and output encoding on user-supplied data within the Web UI.
