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
ubiQuoss Switch VP5208A creates a bcm_password file at /cgi-bin/ with the user credentials in cleartext when a failed login attempt occurs. The file can be reached via an HTTP request. The credentials can be used to access the system via SSH (or TELNET if it is enabled).

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

The ubiQuoss VP5208A switch writes user credentials in cleartext to a file named 'bcm_password' in the /cgi-bin/ directory whenever a failed login attempt occurs. This file is accessible via HTTP, allowing unauthenticated remote attackers to retrieve valid credentials and gain administrative access via SSH or TELNET.

MitigationRestrict or disable HTTP access to /cgi-bin/, disable TELNET and enforce SSH with key-based authentication, and apply vendor firmware updates if available. If the device cannot be patched, consider network isolation or replacement.

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. Confirm device model
    Access the device web interface or check via SNMP/CLI and identify the exact model number. Look for 'VP5208A' or 'Ubiquoss' branding in the device interface or login page.
    Affected if The device is an Ubiquoss VP5208A switch
  2. Verify HTTP service is enabled
    Attempt to access the device's web interface via HTTP on port 80. Check if the login page loads or if HTTP responses are received.
    Affected if HTTP is enabled and the device responds on port 80 (the vulnerability requires HTTP access to the file)
  3. Access the bcm_password file
    Send an HTTP GET request to http://[device-ip]/cgi-bin/bcm_password using a web browser or curl command. No authentication should be required.
    Affected if The file exists and is accessible without authentication, returning cleartext credentials or login attempt data
  4. Check for Telnet service exposure
    Attempt to connect to the device via Telnet on port 23 using the retrieved credentials or test if port 23 is open.
    Affected if Telnet service is accessible and accepts the credentials found in the file

If the device is a Ubiquoss VP5208A with HTTP enabled and the /cgi-bin/bcm_password file is accessible, the device is affected by this vulnerability and credentials can be retrieved by unauthenticated attackers.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict or disable HTTP access to /cgi-bin/, disable TELNET and enforce SSH with key-based authentication, and apply vendor firmware updates if available. If the device cannot be patched, consider network isolation or replacement.
