CVE-2023-46187
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 InfoSphere Master Data Management 11.6, 12.0, and 14.0 is vulnerable to stored 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.
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 InfoSphere Master Data Management versions 11.6, 12.0, and 14.0 is vulnerable to stored cross-site scripting (XSS). An authenticated user can embed malicious JavaScript code into the Web UI, which is then executed in the browsers of other users viewing that content. This can lead to session hijacking and credentials disclosure within trusted sessions.

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.
-
Confirm IBM InfoSphere MDM is installedCheck for the presence of IBM InfoSphere Master Data Management installation directories or look for related services running on the system. Common installation paths may include IBM WebSphere application server with MDM components.Affected if The product is installed on the system
-
Identify installed versionLocate the version information for the MDM installation. This is typically found in installation logs, about pages within the Web UI, or version files within the installation directory. Compare against the affected versions: 11.6, 12.0, or 14.0.Affected if The installed version is exactly 11.6, 12.0, or 14.0
-
Verify Web UI is accessibleConfirm the IBM InfoSphere MDM web interface is accessible by attempting to reach the typical MDM web ports (such as 9443, 9080, or configured custom ports) via browser or curl request. Check if the Web UI login page loads.Affected if The Web UI is accessible and accepts user authentication
-
Check for authenticated user accessDetermine if regular user accounts or low-privilege accounts can log into the Web UI. Stored XSS requires an authenticated user to inject malicious script into content viewed by other users.Affected if Authenticated users can access and submit content through the Web UI
A system is affected if IBM InfoSphere Master Data Management versions 11.6, 12.0, or 14.0 is installed with the Web UI component accessible to authenticated users who can embed custom content.

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 robust input validation and output encoding/sanitization for all user-supplied data rendered in the Web UI. Additionally, deploy Content Security Policy (CSP) headers to mitigate XSS execution.
