CVE-2021-39055
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 Spectrum Copy Data Management 2.2.0.0 through 2.2.14.3 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: 214534.
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 confidenceIBM Spectrum Copy Data Management versions 2.2.0.0 through 2.2.14.3 contain a stored cross-site scripting (XSS) vulnerability in the web interface. An authenticated attacker can embed arbitrary JavaScript code into the Web UI that executes in the browsers of other users viewing the affected content, potentially leading 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 Spectrum Copy Data Management is installedLocate the installation directory or check system services for IBM Spectrum Copy Data Management componentsAffected if The product is present on the system
-
Identify the installed versionAccess the product's version information through its administrative console, about page, or installation metadataAffected if The version falls within 2.2.0.0 through 2.2.14.3
-
Verify the web interface is enabledConfirm the web-based management console is accessible and operationalAffected if The web interface is exposed and accessible to users
-
Review web interface for suspicious injected contentExamine user-generated fields, stored comments, configuration entries, or any content areas where other users input data for unexpected script tags or encoded JavaScriptAffected if Arbitrary script content exists in fields that other users would view
A user is affected if IBM Spectrum Copy Data Management version 2.2.0.0 through 2.2.14.3 is installed with the web interface enabled and accessible, or if evidence of injected script content is found in the web interface.
