Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A directory traversal vulnerability exists in the confd.exe module in Honeywell Experion PKS R40x before R400.6, R41x before R410.6, and R43x before R430.2, which could lead to possible information disclosure. Honeywell strongly encourages and recommends all customers running unsupported versions of EKPS prior to R400 to upgrade to a supported version.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A directory traversal vulnerability in the confd.exe module of Honeywell Experion PKS allows attackers to access files outside the intended directory using path traversal sequences (e.g., ../), potentially exposing sensitive system files, configurations, and credentials.

MitigationUpgrade Honeywell Experion PKS to a supported version (R400.6, R410.6, or R430.2 depending on product line) as specified by Honeywell's advisory; unsupported versions should be prioritized for remediation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Experion PKS version
    Locate the Honeywell Experion PKS installation and retrieve the version information from the system, typically found in the control system documentation, registry, or version info associated with the Experion software components
    Affected if The installed version falls within any of these ranges: >= r400 and < r400.6, OR >= r410 and < r410.6, OR >= r430 and < r430.2
  2. Locate the confd.exe module
    Search for the confd.exe file within the Honeywell Experion installation directory, typically under the Experion system folders or controllers directory
    Affected if The confd.exe module exists in the installation and corresponds to a vulnerable version from step 1
  3. Determine if confd.exe is network-accessible
    Check the network configuration, firewall rules, or service bindings to determine if the confd.exe service is exposed to network access (TCP/UDP ports it listens on)
    Affected if The confd.exe service is running and bound to a network interface accessible to untrusted users
  4. Verify path traversal access
    If confd.exe is accessible, attempt a controlled test request using path traversal sequences (such as ../) to confirm whether the module allows directory traversal outside the intended directory
    Affected if The confd.exe module responds to path traversal requests and returns files from directories outside its intended scope

The environment is affected if Experion PKS version is below r400.6, r410.6, or r430.2 (depending on product line) AND the confd.exe module is present and network-accessible, allowing path traversal requests to reach system files.
