CVE-2020-6654: DLL Hijacking

A DLL Hijacking vulnerability in Eaton's 9000x Programming and Configuration Software v 2.0.38 and prior allows an attacker to execute arbitrary code by replacing the required DLLs with malicious DLLs when the software try to load vci11un6.DLL and cinpl.DLL.

Security readout for executives and security teams

Plain-English summary

CVE-2020-6654 is a high-severity DLL hijacking issue in Eaton 9000x Programming and Configuration Software v2.0.38 and earlier. If a malicious DLL is placed where the application loads required libraries, code can run with the user's privileges after the software is launched.

Executive priority

Treat as a focused endpoint risk, not an internet-wide emergency. Prioritize workstations that manage operational equipment, especially where shared access, weak directory permissions, or untrusted file handling exists.

Technical view

The software attempts to load vci11un6.DLL and cinpl.DLL in a way that can allow DLL replacement or search-order hijacking. The CVSS 3.1 score is 7.8, local attack vector, low complexity, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to systems with Eaton 9000x Programming and Configuration Software v2.0.38 or earlier installed. Risk is most relevant on engineering or maintenance workstations where untrusted users or files can influence directories used by the application.

Exploitation context

The bundle does not show CISA KEV listing or cited evidence of active exploitation. The scenario is local and user-assisted: the software must load a substituted DLL. Evidence in the bundle does not establish remote exploitation.

Researcher notes

The public bundle identifies CWE-426 and CWE-427 and names the DLLs involved. It does not provide a fixed version, patch details, or exploitation evidence, so validation should remain asset- and configuration-focused until Eaton guidance is reviewed.

Mitigation direction

  • Inventory hosts running Eaton 9000x Programming and Configuration Software.
  • Check Eaton's advisory for supported remediation or replacement guidance.
  • Remove or isolate unsupported affected installations where feasible.
  • Restrict write access to application and working directories.
  • Limit use to trusted workstations and trusted file locations only.

Validation and detection

  • Confirm installed 9000x software versions on managed endpoints.
  • Check whether v2.0.38 or earlier is present.
  • Review filesystem permissions around the application and launch directories.
  • Verify whether vendor guidance has been applied.
  • Monitor for unexpected vci11un6.DLL or cinpl.DLL files near the application.
