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
Western Digital WD My Book World through II 1.02.12 suffers from Broken Authentication, which allows an attacker to access the /admin/ directory without credentials. An attacker can easily enable SSH from /admin/system_advanced.php?lang=en and login with the default root password welc0me.

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.

How this class of weakness works · CWE-798

A password or key is baked into the source or binary, so anyone who obtains the code obtains the credential. These are trivially found once the software is distributed. Remediation means removing the secret, rotating it, and loading credentials from secured configuration at runtime.

General guidance for the hard-coded credentials class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →

Upgrade available Upgrade to a release after 1.02.12
Recommended fix Moderate confidence
  1. 1. Isolate the WD My Book device on a separate VLAN or network segment away from sensitive systems and the public internet
  2. 2. Configure firewall rules to block all external access to the device's admin interface (ports 80/443) and SSH (port 22) from untrusted networks
  3. 3. If remote access is required, implement VPN authentication before allowing any traffic to reach the device
  4. 4. Disable SSH access on the device if not explicitly needed; if needed, restrict SSH to limited IP addresses via firewall
  5. 5. Monitor network logs for any suspicious access attempts to /admin/ endpoints
  6. 6. Consider retiring and replacing this device as it is end-of-life and likely no longer receiving security updates from Western Digital
Caveat No firmware update appears to be available from Western Digital for this end-of-life device; the manufacturer has likely discontinued support
