CVE intelligence and bounded remediation

CVE-2019-18267 — An issue was found in GE S2020/S2020G Fast Switch 61850, S2020/S2020G Fast Switch 61850 Versions 07A03 and prior

Medium CVSS 5.4

An issue was found in GE S2020/S2020G Fast Switch 61850, S2020/S2020G Fast Switch 61850 Versions 07A03 and prior. An attacker can inject arbitrary Javascript in a specially crafted HTTP request that may be reflected back in the HTTP response. The device is also vulnerable to a stored cross-site scripting vulnerability that may allow session hijacking, disclosure of sensitive data, cross-site request forgery (CSRF) attacks, and remote code execution.

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.
