CVE-2020-24051 — Moog Exvf5C-2 Firmware security vulnerability
The Moog EXO Series EXVF5C-2 and EXVP7C2-3 units support the ONVIF interoperability IP-based physical security protocol, which requires authentication for some of its operations. It was found that the authentication check for those ONVIF operations can be bypassed. An attacker can abuse this issue to execute privileged operations without authentication, for instance, to create a new Administrator user.

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.
