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
An issue was discovered on Phoenix Contact Emalytics Controller ILC 2050 BI before 1.2.3 and BI-L before 1.2.3 devices. There is an insecure mechanism for read and write access to the configuration of the device. The mechanism can be discovered by examining a link on the website of the device.

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

The Phoenix Contact Emalytics Controller ILC 2050 BI and BI-L devices before version 1.2.3 contain an insecure mechanism allowing unauthorized read and write access to device configuration. This access mechanism can be discovered by examining a link on the device's web interface, exposing sensitive configuration data and allowing modification of device settings.

MitigationUpgrade Phoenix Contact Emalytics Controller ILC 2050 BI and BI-L devices to firmware version 1.2.3 or later to address the insecure configuration access mechanism.

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. Determine the device firmware version
    Access the device's web interface or administrative console and navigate to the system information or firmware version settings page. This is typically found in the device's 'System', 'About', or 'Status' section.
    Affected if The displayed firmware version is earlier than 1.2.3 (e.g., 1.2.2, 1.2.1, 1.2.0, or any version number less than 1.2.3)
  2. Verify the web interface is accessible
    Confirm you can reach the device's web interface by entering the device's IP address in a web browser. The device should present a login page or status page.
    Affected if The web interface is accessible over the network (this is a prerequisite for the vulnerability to be exploitable)
  3. Check for the exposed configuration link
    After logging into the web interface, examine the page source or navigate through the menus to look for any links or endpoints that provide direct access to device configuration settings without additional authentication. Look for URLs or links that may expose configuration parameters directly.
    Affected if A direct link or endpoint exists that allows unauthorized access to read or modify device configuration settings without proper authentication
  4. Identify if configuration can be modified without authorization
    Attempt to access the configuration area through the exposed link mechanism. Determine if sensitive settings such as network configuration, device parameters, or system settings can be viewed or altered without requiring elevated privileges beyond the standard web login.
    Affected if Configuration data can be read or written through an undocumented or insecure mechanism that bypasses normal authentication controls

The device is affected if it runs firmware version earlier than 1.2.3 and exposes an unauthenticated configuration access mechanism through its web interface.

dbcve · scoped
Upgrade available Upgrade to 1.2.3 or later
Fixed in 1.2.3
Interim mitigation

Upgrade Phoenix Contact Emalytics Controller ILC 2050 BI and BI-L devices to firmware version 1.2.3 or later to address the insecure configuration access mechanism.

Recommended fix High confidence

Firmware version 1.2.3

  1. Obtain firmware version 1.2.3 or later from the official Phoenix Contact support website or trusted distribution channel
  2. Review the official Phoenix Contact firmware upgrade documentation for the ILC 2050 BI and BI-L devices
  3. Create a backup of the current device configuration before performing the upgrade
  4. Follow the vendor's recommended firmware upgrade procedure, typically involving uploading the firmware file through the device's web interface or management tool
  5. Verify the upgrade was successful by checking the firmware version in the device management interface
  6. Confirm the insecure configuration access mechanism is no longer accessible
