CVE-2020-15768
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 · uneditedAn issue was discovered in Gradle Enterprise 2017.3 - 2020.2.4 and Gradle Enterprise Build Cache Node 1.0 - 9.2. Unrestricted HTTP header reflection in Gradle Enterprise allows remote attackers to obtain authentication cookies, if they are able to discover a separate XSS vulnerability. This potentially allows an attacker to impersonate another user. Gradle Enterprise affected application request paths:/info/headers, /cache-info/headers, /admin-info/headers, /distribution-broker-info/headers. Gradle Enterprise Build Cache Node affected application request paths:/cache-node-info/headers.
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 confidenceUnrestricted HTTP header reflection in Gradle Enterprise (versions 2017.3-2020.2.4) and Gradle Enterprise Build Cache Node (1.0-9.2) allows remote attackers to obtain authentication cookies via paths /info/headers, /cache-info/headers, /admin-info/headers, /distribution-broker-info/headers, and /cache-node-info/headers, but only if a separate XSS vulnerability is discoverable, enabling potential user impersonation.

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 Gradle Enterprise versionCheck the product UI footer, about page, or check startup logs for the version numberAffected if Version is 2017.3 through 2020.2.4 (inclusive)
-
Identify Build Cache Node versionCheck the admin interface, startup logs, or the node's /version endpointAffected if Version is 1.0 through 9.2 (inclusive)
-
Test vulnerable endpoint accessibilitySend HTTP requests to /info/headers, /cache-info/headers, /admin-info/headers, /distribution-broker-info/headers, and /cache-node-info/headersAffected if Any endpoint returns an HTTP 200 response (endpoint is accessible)
-
Inspect response for header reflectionAnalyze response headers from the above endpoints for unexpected or sensitive headersAffected if Response contains authentication-related headers such as cookies, authorization tokens, or session identifiers
You are affected if you run Gradle Enterprise 2017.3-2020.2.4 or Build Cache Node 1.0-9.2 and the vulnerable /info/headers (or similar) endpoints are accessible and return sensitive headers.

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 dataUpgrade to Gradle Enterprise 2020.2.5 or later and Build Cache Node 9.3 or later to patch the unrestricted header reflection; additionally, investigate and remediate any concurrent XSS vulnerabilities to fully mitigate the impersonation risk.
