CVE-2020-7574 — Siemens Climatix Pol908 Firmware security vulnerability

Medium CVSS 6.1

A vulnerability has been identified in Climatix POL908 (BACnet/IP module) (All versions), Climatix POL909 (AWM module) (All versions < V11.32). A persistent cross-site scripting (XSS) vulnerability exists in the "Server Config" web interface of the affected devices that could allow an attacker to inject arbitrary JavaScript code. The code could be potentially executed later by another (possibly privileged) user. The security vulnerability could be exploited by an attacker with network access to the affected system.

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.
