CVE-2023-0010
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 · uneditedA reflected cross-site scripting (XSS) vulnerability in the Captive Portal feature of Palo Alto Networks PAN-OS software can allow a JavaScript payload to be executed in the context of an authenticated Captive Portal user’s browser when they click on a specifically crafted link.
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 confidenceA reflected cross-site scripting (XSS) vulnerability exists in the Captive Portal feature of Palo Alto Networks PAN-OS software. The flaw allows a remote attacker to inject malicious JavaScript code into the Captive Portal web interface through a specifically crafted URL. When an authenticated user clicks on this malicious link, the payload executes within their browser context, potentially enabling session hijacking or credential theft.

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.
-
Check PAN-OS versionRun 'show system info' via CLI or check the version in the PAN-OS web interface under Device > Setup > OperationsAffected if The installed version is 8.1.0-8.1.24, 9.0.0-9.0.17, 9.1.0-9.1.16, 10.0.0-10.0.11, 10.1.0-10.1.6, or 10.2.0-10.2.2
-
Verify Captive Portal is enabledCheck PAN-OS configuration under Network > Captive Portal or via CLI 'show system setting captive-portal'Affected if Captive Portal is enabled and accessible to users
-
Confirm authentication is configured for Captive PortalReview Captive Portal settings to determine if user authentication (local database, RADIUS, LDAP, or certificate) is required for accessAffected if Authentication is enabled, meaning users must log in before accessing Captive Portal
Your environment is affected if the PAN-OS version falls within the affected ranges AND Captive Portal is enabled with authentication configured, allowing authenticated users to access the Captive Portal web interface.
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 dataApply the applicable PAN-OS security patch from Palo Alto Networks. Until patched, restrict user access to Captive Portal and warn users not to click untrusted links. Consider disabling Captive Portal if not operationally required.
