CVE-2024-6558 — HMS Industrial Networks Anybus-CompactCom 30 products are vulnerable to a XSS attack caused by the lack of input sanitation checks

Medium CVSS 6.3

HMS Industrial Networks Anybus-CompactCom 30 products are vulnerable to a XSS attack caused by the lack of input sanitation checks. As a consequence, it is possible to insert HTML code into input fields and store the HTML code. The stored HTML code will be embedded in the page and executed by host browser the next time the page is loaded, enabling social engineering attacks.

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.
