CVE-2025-33008
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 6.2.1.0 and IBM Sterling File Gateway 6.2.1.0 is vulnerable to cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
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 confidenceStored cross-site scripting (XSS) vulnerability in IBM Sterling B2B Integrator 6.2.1.0 and IBM Sterling File Gateway 6.2.1.0 Web UI. An authenticated attacker can inject arbitrary JavaScript code that executes in other users' browsers within trusted sessions, 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.
-
Identify IBM Sterling B2B Integrator versionLocate the version file or check the product about section in the administration console. Typical methods include reviewing install logs, the version.properties file, or accessing the System Information page in the Web UI.Affected if The installed version is exactly 6.2.1.0
-
Identify IBM Sterling File Gateway versionLocate the version file or check the product about section in the administration console. Review install logs, version.properties, or access System Information in the Web UI.Affected if The installed version is exactly 6.2.1.0 and the product is deployed
-
Verify Web UI is accessibleConfirm the Web UI interface is enabled and reachable. Typically accessed via browser on the configured port (commonly 8443 or 443). Check if the login page loads.Affected if The Web UI is exposed and users have authenticated access to it
-
Inspect user-supplied data storage points in Web UIReview forms, input fields, and data submission points in the Web UI where user content gets stored and displayed back to other users. Common areas include file transfer metadata, user profiles, and notification settings.Affected if User-supplied data in Web UI input fields is stored and rendered without proper encoding to other users
Your environment is affected if you are running exactly version 6.2.1.0 of IBM Sterling B2B Integrator or IBM Sterling File Gateway and the Web UI is enabled with authenticated user access.

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 input validation and output encoding on all user-supplied data in the Web UI. Apply vendor security patches when released. Consider implementing Content Security Policy (CSP) headers to mitigate XSS execution.
