Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/pen-drive/pen-drive-scanner-rhel9.
  2. 2Review the reported fix. Source-reported workaround: The following practices would help for avoiding exposure and mitigate this flaw: - Upgrade Pen Drive to version 1.0.0-2 or later, which reportedly contains the fix. - Until upgraded, review HTML reports generated by Pen Drive before opening them in a browser, or open them in a sandboxed browser environment. - If using must-gather archives from untrusted sources, validate the archive content before feeding it to Pen Drive. - Consider opening Pen Drive reports with JavaScript disabled in the browser.

Upstream source description

A flaw was found in the Pen Drive report generator. Cluster-sourced data is rendered into HTML reports without proper escaping or sanitization. An attacker with cluster administrator privileges can inject a stored cross-site scripting (XSS) payload into cluster objects (such as ClusterVersion spec.channel) that executes in the browser of any user who opens the generated HTML report.
