CVE-2018-10139
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 · uneditedThe PAN-OS response for GlobalProtect Gateway in Palo Alto Networks PAN-OS 6.1.21 and earlier, PAN-OS 7.1.18 and earlier, PAN-OS 8.0.11 and earlier may allow an unauthenticated attacker to inject arbitrary JavaScript or HTML. PAN-OS 8.1 is NOT affected.
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 confidenceAn unauthenticated attacker can inject arbitrary JavaScript or HTML into the GlobalProtect Gateway response in Palo Alto Networks PAN-OS versions 6.1.21 and earlier, 7.1.18 and earlier, and 8.0.11 and earlier, resulting in a stored Cross-Site Scripting (XSS) vulnerability. PAN-OS 8.1 is not affected.

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 PAN-OS versionAccess the PAN-OS management interface or CLI and retrieve the system version using 'show system info' or check the Dashboard > Device Summary in the web interfaceAffected if The installed version falls within 6.1.21 or earlier, 7.1.0-7.1.18, or 8.0.0-8.0.11 (versions 8.1 and later are not affected)
-
Verify GlobalProtect Gateway is enabledCheck the PAN-OS web interface under Network > GlobalProtect > Gateways, or use CLI 'show global-protect gateway' to list configured gatewaysAffected if Any GlobalProtect Gateway is defined and active in the environment
-
Inspect GlobalProtect Gateway SSL/TLS settingsReview the GlobalProtect Gateway configuration under Network > GlobalProtect > Gateways > SSL/TLS Service Profile, looking for how the portal and gateway respond to authentication requestsAffected if The gateway accepts unauthenticated connections and returns user-controlled content in responses
-
Monitor for anomalous GlobalProtect responsesCapture and review HTTP responses from the GlobalProtect Gateway endpoint for unexpected script tags, HTML markup, or JavaScript code in what should be system-generated contentAffected if Arbitrary JavaScript or HTML appears in stored GlobalProtect Gateway responses that was not authored by the administrator
You are affected if your PAN-OS version is 6.1.21 or earlier, 7.1.0-7.1.18, or 8.0.0-8.0.11 AND you have a GlobalProtect Gateway enabled that can be reached by unauthenticated attackers.
Generated from the published advisory. Verify against your own configuration.
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 PAN-OS to version 7.1.19 or later, 8.0.12 or later, or 8.1 or later to resolve this XSS vulnerability in the GlobalProtect Gateway component.
