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 ServiceNow versionAccess the ServiceNow system properties or about page (typically via System Properties > About or /nav_to.do?uri=about.do) to determine the installed version name and numberAffected if The installed version is one of: San Diego, Tokyo, or Utah (or their corresponding version numbers)
-
Verify Polaris Layout is activeCheck the user's UI preference or system property that controls the Polaris layout. This can typically be found in User Preferences > UI Preferences or via the 'glide.ui.polaris.enabled' system propertyAffected if Polaris Layout is enabled or users are configured to use Polaris as their default UI experience
-
Confirm authenticated accessVerify that standard or basic users have the ability to interact with Polaris-based pages. Check user roles and the ability to access ServiceNow tables via the Polaris interfaceAffected if Standard (non-admin) authenticated users can access Polaris functionality
-
Check for vulnerable URL patternsReview application logs or proxy traffic for requests to Polaris endpoints containing unsanitized parameters. Focus on reflected parameters in URLs that include user input without proper encodingAffected if URLs in the Polaris interface contain reflected user-supplied parameters without sanitization
The environment is affected if running ServiceNow San Diego, Tokyo, or Utah versions with Polaris Layout enabled and standard users have access to the Polaris interface.
