CVE-2022-1737: Pyramid Solutions EtherNet/IP Adapter Development Kit Out-of-bound Write

Pyramid Solutions' affected products, the Developer and DLL kits for EtherNet/IP Adapter and EtherNet/IP Scanner, are vulnerable to an out-of-bounds write, which may allow an unauthorized attacker to send a specially crafted packet that may result in a denial-of-service condition.

Security readout for executives and security teams

Plain-English summary

This flaw affects Pyramid Solutions EtherNet/IP development and DLL kits used in industrial communication software. An unauthenticated network attacker could send a malformed packet that may crash affected software. The CVSS score is critical, but the supplied description only confirms denial of service, not confirmed takeover.

Executive priority

Treat this as high-priority for industrial environments because unauthenticated network traffic can trigger service disruption. Prioritize asset discovery and exposure reduction while confirming vendor remediation, especially for systems supporting production uptime or safety-adjacent operations.

Technical view

CVE-2022-1737 is a CWE-787 out-of-bounds write in Pyramid Solutions EtherNet/IP Adapter and Scanner kits. A remote unauthenticated attacker can send a specially crafted packet. CVSS 3.1 is 9.8 with high C/I/A impact, but the source description specifically states denial of service may result.

Likely exposure

Exposure is most likely in OT or industrial products built with Pyramid Solutions EtherNet/IP Adapter or Scanner Developer/DLL kits. Downstream exposure may exist where vendors embedded these kits, but the provided sources do not identify downstream OEM products or deployments.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. The issue is network reachable, low complexity, and requires no authentication or user interaction, which raises urgency for internet-exposed or poorly segmented industrial environments.

Researcher notes

Do not assume code execution from the supplied description. The CVSS vector rates confidentiality, integrity, and availability high, but the narrative evidence only states denial of service. Downstream product impact is uncertain without vendor-specific inclusion data.

Mitigation direction

  • Check Pyramid Solutions and CISA guidance for supported updates or compensating controls.
  • Inventory products using the affected Adapter or Scanner kits.
  • Reduce network exposure for affected EtherNet/IP services.
  • Restrict access to trusted OT management networks only.
  • Ask downstream vendors whether their products include these affected kits.

Validation and detection

  • Confirm whether EADK, EIPA, EDKS, or EIPS components are present.
  • Map network paths to systems exposing EtherNet/IP services.
  • Verify affected versions against vendor documentation and procurement records.
  • Review device crash or restart events for unexplained malformed traffic impact.
  • Document downstream vendor responses for products built on these kits.
