CVE-2020-4281
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 DOORS Next Generation (DNG/RRC) 6.0.2, 6.0.6, 6.0.6.1, and 7.0 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: 176141.
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 DOORS Next Generation versions 6.0.2, 6.0.6, 6.0.6.1, and 7.0 contain a cross-site scripting (XSS) vulnerability in the Web UI. The vulnerability allows authenticated users to embed arbitrary JavaScript code through user input fields or URLs, which executes in the browsers of other users viewing the same content. This can lead to session hijacking and credentials disclosure within trusted sessions due to the malicious script executing in the context of the trusted domain.

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 DOORS Next Generation versionAccess the IBM Jazz Team Server administrative console or check the installation directory for version information. Typically found in the About section of the admin UI or via the repotools command with the -version parameter.Affected if The installed version matches exactly 6.0.2, 6.0.6, 6.0.6.1, or 7.0
-
Confirm Web UI component is activeVerify that the DOORS Next Generation Web UI is accessible and in use. Check if users access the system via web browser rather than only the rich client.Affected if The Web UI interface is enabled and accessible to users
-
Verify user input fields are presentNavigate through the DOORS Next Generation Web UI and identify user-controllable input areas such as artifact attributes, hyperlinks, or discussion fields.Affected if User input fields exist in the Web UI where arbitrary text can be entered
The environment is affected if IBM DOORS Next Generation version 6.0.2, 6.0.6, 6.0.6.1, or 7.0 is installed and the Web UI component is enabled and accessible to 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's official patches for this vulnerability. Until patches are applied, implement content security policy (CSP) headers and validate/sanitize all user-supplied input on the client and server side to prevent JavaScript injection.
