CVE-2016-10308 — Siklu Etherhaul Firmware security vulnerability
Critical
CVSS 9.8
Siklu EtherHaul radios before 3.7.1 and 6.x before 6.9.0 have a built-in, hidden root account, with an unchangeable password that is the same across all devices. This account is accessible via both SSH and the device's web interface and grants access to the underlying embedded Linux 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.
