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 CWE-287: Improper Authentication vulnerability exists in the NET55XX Encoder with firmware prior to version 2.1.9.7 which could cause impact to confidentiality, integrity, and availability when a remote attacker crafts a malicious request to the encoder webUI.

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 CWE-287 Improper Authentication vulnerability in the NET55XX Encoder webUI allows remote attackers to bypass authentication mechanisms with malicious requests. This affects devices running firmware versions prior to 2.1.9.7, potentially giving attackers unauthorized access to compromise confidentiality, integrity, and availability.

MitigationUpdate NET55XX Encoder firmware to version 2.1.9.7 or later to remediate the improper authentication vulnerability.

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 the NET55XX encoder model
    Locate the device label or access the webUI system information page to confirm the exact model (Net5500, Net5501, Net5501 I, Net5501 Xt, Net5504, Net5508, or Net5516).
    Affected if The device is any NET55XX encoder model.
  2. Determine the installed firmware version
    Access the webUI admin interface and navigate to System Information or Firmware/Upgrade settings to view the currently installed firmware version. Alternatively, check the device label or documentation for firmware version sticker.
    Affected if The installed firmware version cannot be determined or is visible.
  3. Compare firmware version against the affected range
    Compare the installed firmware version number to 2.1.9.7. The vulnerability affects all versions prior to 2.1.9.7.
    Affected if The installed firmware version is below 2.1.9.7.
  4. Confirm webUI is accessible
    Verify that the device web interface is reachable on the network by attempting to access the device IP on ports 80 or 443, or by checking network listening services on the device.
    Affected if The webUI is exposed and accessible on the network.

The environment is affected if the NET55XX encoder device is running firmware version lower than 2.1.9.7 and the webUI is network-accessible.

Upgrade available Upgrade to 2.1.9.7 or later
Fixed in 2.1.9.7
Interim mitigation

Update NET55XX Encoder firmware to version 2.1.9.7 or later to remediate the improper authentication vulnerability.

Recommended fix High confidence

Firmware version 2.1.9.7

  1. Identify the exact Net55XX model (Net5501, Net5501 I, Net5501 Xt, Net5504, Net5500, Net5516, or Net5508) currently deployed
  2. Access the encoder webUI or management interface
  3. Navigate to the firmware upgrade section
  4. Download the firmware version 2.1.9.7 or later from the official Schneider Electric website (www.se.com)
  5. Upload and apply the firmware version 2.1.9.7 to the encoder device
  6. Verify the upgrade was successful by checking the firmware version in the device management interface
  7. Confirm the webUI is accessible and the vulnerability is remediated
