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 privilege escalation vulnerability exists in the Rockwell Automation affected products. The vulnerability occurs due to improper default file permissions allowing users to exfiltrate credentials and escalate privileges.

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 · moderate confidence

A privilege escalation vulnerability in Rockwell Automation products stems from improper default file permissions that allow authenticated users to access sensitive files containing credentials, enabling vertical privilege escalation beyond the user's intended authorization level.

MitigationReview and remediate file permissions on the affected product installations to ensure only privileged administrators can access sensitive configuration and credential files; follow principle of least privilege.

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 product and firmware version
    Access the device's system information or firmware update settings, or use the manufacturer's diagnostic tool to retrieve the current firmware version. This is typically found in Settings > About or System Information on the panel interface, or via the firmware version command-line tool if available.
    Affected if The firmware version matches one of these ranges: 2800c Optixpanel Compact: 4.0.0.325 through 4.0.2.115; 2800s Optixpanel Standard: 4.0.0.350 through 4.0.2.122; Embedded Edge Compute Module: 4.0.0.347 through 4.0.2.105.
  2. Verify file permission configuration
    Locate the sensitive configuration or credential storage directories on the device filesystem. Use standard file system inspection commands (such as ls -la or the equivalent for the embedded platform) to examine the permissions on files that store passwords, keys, or authentication credentials.
    Affected if Non-privileged authenticated users can read files that should only be accessible to administrative accounts, indicating overly permissive file permissions.
  3. Test unauthorized credential file access
    Using a standard authenticated user account (non-administrator), attempt to navigate to and read known sensitive file locations such as configuration directories, credential stores, or password files that should be restricted.
    Affected if A non-administrator user can successfully read sensitive credential or configuration files that should be protected.

The device is affected if it runs a firmware version within the affected ranges AND allows non-privileged authenticated users to read sensitive credential or configuration files due to permissive file permissions.

Fixed in 4.0.2.1064.0.2.1164.0.2.123
Interim mitigation

Review and remediate file permissions on the affected product installations to ensure only privileged administrators can access sensitive configuration and credential files; follow principle of least privilege.

Recommended fix High confidence

Upgrade to firmware 4.0.2.116 (2800c), 4.0.2.123 (2800s), or 4.0.2.106 (Embedded Edge Compute Module)

  1. 1. Identify the specific device model (2800c Optixpanel Compact, 2800s Optixpanel Standard, or Embedded Edge Compute Module)
  2. 2. Backup all current configuration and data from the device
  3. 3. Download the appropriate firmware version from Rockwell Automation's official support website: 4.0.2.116 for 2800c, 4.0.2.123 for 2800s, or 4.0.2.106 for Embedded Edge Compute Module
  4. 4. Verify the integrity of the firmware file using checksums provided by Rockwell Automation
  5. 5. Connect to the device through a secure, trusted network connection
  6. 6. Access the device's firmware update interface (typically via the web-based management console or Rockwell's programming software)
  7. 7. Upload and apply the new firmware version
  8. 8. After the update completes, verify the device boots into the new firmware version
