Medium CVSS 6.1

Cross-site Scripting (XSS) vulnerability in the 'notes' field of a discovered scan asset in Rapid7 Metasploit Pro allows an attacker with a specially-crafted network service of a scan target store an XSS sequence in the Metasploit Pro console, which will trigger when the operator views the record of that scanned host in the Metasploit Pro interface. This issue affects Rapid7 Metasploit Pro version 4.17.1-20200427 and prior versions, and is fixed in Metasploit Pro version 4.17.1-20200514.

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
