CVE-2023-4667 — The web interface of the PAC Device allows the device administrator user profile to store malicious scripts in some fields

High CVSS 8.1

The web interface of the PAC Device allows the device administrator user profile to store malicious scripts in some fields. The stored malicious script is then executed when the GUI is opened by any users of the webserver administration interface. The root cause of the vulnerability is inadequate input validation and output encoding in the web administration interface component of the firmware. This could lead to unauthorized access and data leakage

Matched remediation archetype

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.
