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: 214619.
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 confidenceCross-site scripting (XSS) vulnerability in IBM Jazz Foundation Web UI affecting versions 6.0.6 through 7.0.2. Attackers can embed arbitrary JavaScript code that executes in the context of trusted sessions, potentially leading to credential 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 Jazz Foundation installationCheck for IBM Jazz Foundation installation directories (typically under /opt/ibm or C:\Program Files\ibm on Windows), or look for jazz\/server directory structures. Query system services or running processes for jazz or rmicytejar names.Affected if IBM Jazz Foundation software is present on the system
-
Determine installed IBM Jazz Foundation versionLocate the version information file or check the Jazz Team Server admin interface. The version is often stored in a manifest, about page, or version.properties file in the installation directory.Affected if The installed version cannot be determined or is not documented
-
Compare version against affected rangeVerify if the installed version is 6.0.6, 6.0.6.1, 7.0, 7.0.1, or 7.0.2. The affected range spans from 6.0.6 through 7.0.2 inclusive.Affected if Installed version matches 6.0.6, 6.0.6.1, 7.0, 7.0.1, or 7.0.2 exactly
-
Confirm Web UI is accessibleCheck if the Jazz Web UI (typically accessible via browser on port 9443 or similar) is currently running and accessible. This confirms the attack surface exists.Affected if The Jazz Web UI interface is active and reachable
A user is affected if IBM Jazz Foundation versions 6.0.6 through 7.0.2 are installed and the Web UI component is accessible.

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 security patch for CVE-2021-39059. Until patched, implement Content Security Policy (CSP) headers and validate/sanitize all user inputs in the Web UI to reduce XSS impact.
