CVE-2020-12038 — Rockwellautomation Eds Subsystem security vulnerability

Medium CVSS 5.5

Products that use EDS Subsystem: Version 28.0.1 and prior (FactoryTalk Linx software (Previously called RSLinx Enterprise): Versions 6.00, 6.10, and 6.11, RSLinx Classic: Version 4.11.00 and prior, RSNetWorx software: Version 28.00.00 and prior, Studio 5000 Logix Designer software: Version 32 and prior) is vulnerable. A memory corruption vulnerability exists in the algorithm that matches square brackets in the EDS subsystem. This may allow an attacker to craft specialized EDS files to crash the EDSParser COM object, leading to denial-of-service conditions.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

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

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
