CVE-2016-10307 — Gotrango Apex Lynx Firmware security vulnerability

Critical CVSS 9.8

Trango ApexLynx 2.0, ApexOrion 2.0, GigaLynx 2.0, GigaOrion 2.0, and StrataLink 3.0 devices have a built-in, hidden root account, with a default password for which the MD5 hash value is public (but the cleartext value is perhaps not yet public). 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.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
