CVE intelligence and bounded remediation

CVE-2020-14478 — Rockwellautomation Factorytalk Services Platform security vulnerability

High CVSS 7.1

A local, authenticated attacker could use an XML External Entity (XXE) attack to exploit weakly configured XML files to access local or remote content. A successful exploit could potentially cause a denial-of-service condition and allow the attacker to arbitrarily read any local file via system-level services.

Matched remediation archetype

XML external entity and unsafe XML processing

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory XML parsers used by APIs, file imports, office or image formats, identity protocols, feeds, and background jobs.
  • Determine whether document type declarations, external entities, XInclude, schemas, or network resolvers are enabled.
  • Map parser filesystem and network access and the sensitivity of documents it processes.

Remediate safely

  • Configure each parser to reject document type declarations and disable external entity, XInclude, and network resolution features.
  • Prefer a data format or hardened parser that does not support external resolution, and apply input size and depth limits.
  • Update affected XML libraries and centralize secure parser construction so callers cannot silently override it.
