CVE-2018-9337
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 web interface administration page in PAN-OS 6.1.20 and earlier, PAN-OS 7.1.17 and earlier, PAN-OS 8.0.10 and earlier, and PAN-OS 8.1.1 and earlier may allow an attacker to inject arbitrary JavaScript or HTML.
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 confidenceThis is a cross-site scripting (XSS) vulnerability in the PAN-OS web-based administration interface. The flaw allows injection of arbitrary JavaScript or HTML through insufficient input validation on the admin login or related pages, likely in a reflected manner.

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 PAN-OS is installedAccess the device console or SSH and run the command 'show system info' or 'show version' to identify the operating system and versionAffected if The device is not running PAN-OS, then this CVE does not apply
-
Identify the PAN-OS version numberFrom the output of 'show system info' or 'show version', note the exact version number displayed (for example, 7.1.15 or 8.0.9)Affected if No version number is returned or the command fails, the PAN-OS version cannot be determined
-
Compare installed version against affected rangesCheck if the installed version falls into any of these ranges: 6.0.x (any version above 6.0.0 through 6.1.20), 7.1.x (7.1.0 through 7.1.17), 8.0.x (8.0.1 through 8.0.10), or 8.1.x (8.1.0 through 8.1.1). Versions outside these ranges (such as 6.1.21+, 7.1.18+, 8.0.11+, 8.1.2+) are not affectedAffected if The installed version is within any of these ranges: >6.0.0 to <=6.1.20, >=7.1.0 to <=7.1.17, >8.0.0 to <=8.0.10, or >=8.1.0 to <=8.1.1
-
Verify web management interface is enabledRun 'show web-server' or check the management interface settings via the CLI to determine if the PAN-OS web-based administration interface (HTTP or HTTPS) is enabledAffected if The web-based management interface is enabled and accessible, making the XSS vulnerability exploitable
You are affected if the device runs PAN-OS with a version number within any of the four affected ranges AND the web-based administration interface is enabled.

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 6.1.21 or later, 7.1.18 or later, 8.0.11 or later, or 8.1.2 or later. Alternatively, restrict access to the management interface to trusted networks only and disable HTTP/HTTPS management if not required.
