CVE-2016-9796 — Alcatel-Lucent Omnivista 8770 Network Management System security vulnerability

Critical CVSS 9.8

Alcatel-Lucent OmniVista 8770 2.0 through 3.0 exposes different ORBs interfaces, which can be queried using the GIOP protocol on TCP port 30024. An attacker can bypass authentication, and OmniVista invokes methods (AddJobSet, AddJob, and ExecuteNow) that can be used to run arbitrary commands on the server, with the privilege of NT AUTHORITY\SYSTEM on the server. NOTE: The discoverer states "The vendor position is to refer to the technical guidelines of the product security deployment to mitigate this issue, which means applying proper firewall rules to prevent unauthorised clients to connect to the OmniVista server."

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.
