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
Sollae Serial-Ethernet-Module and Remote-I/O-Device-Server devices have a default password of sollae for the TELNET service.

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

Sollae Serial-Ethernet-Module and Remote-I/O-Device-Server embedded devices expose a TELNET service with a hardcoded default credential (username: sollae, password: sollae). This default account allows unauthenticated remote attackers to gain full administrative access to the device, enabling potential network intrusion, data exfiltration, or lateral movement.

MitigationChange the default TELNET credentials on all affected Sollae devices to unique, strong passwords immediately. If TELNET is not required, disable the service entirely. Consider network segmentation to isolate IoT/embedded devices.

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 device model
    Access the device administrative interface or check the device label/documentation to determine the exact model number (e.g., H10, H12, H14, M53n, M32, M24, M73, B63n2).
    Affected if The device is one of the following: Eztcp Cie H10, H12, H14, or Eztcp Cse M53n, M32, M24, M73, B63n2.
  2. Confirm TELNET service is enabled
    Attempt to connect to the device on TELNET port 23 (e.g., using 'telnet <device_ip>' or a network scanner). Verify the service responds.
    Affected if TELNET service is exposed and accepting connections on the device.
  3. Test default credential access
    Attempt to log in via TELNET using username 'sollae' and password 'sollae'.
    Affected if Authentication succeeds with the default credentials, granting administrative access.
  4. Verify credential status
    After login, check whether the 'sollae' account still exists or if the password has been changed from the default.
    Affected if The default 'sollae' account remains active with unchanged password.

A user is affected if they own one of the listed Eztcp devices with TELNET enabled and the default 'sollae' credentials still functional.
