CVE-2017-6023 — An issue was discovered in Fatek Automation PLC Ethernet Module

Critical CVSS 9.8

An issue was discovered in Fatek Automation PLC Ethernet Module. The affected Ether_cfg software configuration tool runs on the following Fatek PLCs: CBEH versions prior to V3.6 Build 170215, CBE versions prior to V3.6 Build 170215, CM55E versions prior to V3.6 Build 170215, and CM25E versions prior to V3.6 Build 170215. A stack-based buffer overflow vulnerability has been identified, which may allow remote code execution or crash the affected device.

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.
