CVE-2016-10306
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 · uneditedTrango Altum AC600 devices have a built-in, hidden root account, with a default password of abcd1234. This account is accessible via SSH and/or TELNET, and grants access to the underlying embedded UNIX OS on the device, allowing full control over it.
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 confidenceHardcoded credentials vulnerability in Trango Altum AC600 devices creates a hidden root account with default password 'abcd1234'. This backdoor is accessible via SSH and/or TELNET and provides full root access to the embedded UNIX OS.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify device model and firmware versionAccess the device management interface or check the device label to confirm it is a Trango Altum AC600 or Trango A600 device. Retrieve the firmware version through the admin interface or by running 'cat /proc/version' or 'uname -a' via console/TELNET if available.Affected if The device is a Trango A600 or Altum AC600 running any firmware version.
-
Verify if SSH service is enabledCheck the device configuration through the web admin interface or CLI for SSH service status. If you have console access, run 'ps aux | grep sshd' to check if the SSH daemon is running.Affected if SSH service is enabled and accessible on the device.
-
Verify if TELNET service is enabledCheck the device configuration through the web admin interface or CLI for TELNET service status. If you have console access, run 'ps aux | grep telnet' to check if the TELNET daemon is running.Affected if TELNET service is enabled and accessible on the device.
-
Check for hidden root account existenceIf you have console or SSH/TELNET access to the device, examine /etc/passwd or /etc/shadow files to identify accounts. Look for a root account or any account with UID 0 other than the standard administrator account.Affected if A hidden root account or additional UID 0 account exists in the system.
-
Test authentication with hardcoded credentialsAttempt to authenticate via SSH or TELNET using username 'root' and password 'abcd1234'. This should only be performed on devices you own or have explicit authorization to test, as unauthorized access is illegal.Affected if Authentication succeeds with the root account and password 'abcd1234'.
You are affected if you have a Trango A600 or Altum AC600 device with SSH or TELNET services enabled, and the hidden root account with password 'abcd1234' is present and accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataDisable or remove the hidden root account, change default credentials, disable plaintext TELNET protocol, and restrict network access to device management interfaces. Apply vendor firmware patch if available.
