CVE intelligence and bounded remediation

CVE-2019-19393 — Rittal Cmc Pu Iii 7030.000 Firmware security vulnerability

Medium CVSS 6.1

The Web application on Rittal CMC PU III 7030.000 V3.00 V3.11.00_2 to V3.15.70_4 devices fails to sanitize user input on the system configurations page. This allows an attacker to backdoor the device with HTML and browser-interpreted content (such as JavaScript or other client-side scripts) as the content is always displayed after and before login. Persistent XSS allows an attacker to modify displayed content or to change the victim's information. Successful exploitation requires access to the web management interface, either with valid credentials or a hijacked session.

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.
