CVE-2018-0459
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 · uneditedA vulnerability in the web-based management interface of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker to cause an affected system to reboot or shut down. The vulnerability is due to insufficient server-side authorization checks. An attacker who is logged in to the web-based management interface as a low-privileged user could exploit this vulnerability by sending a crafted HTTP request. A successful exploit could allow the attacker to use the low-privileged user account to reboot or shut down the affected system.
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 confidenceCisco NFVIS web-based management interface has insufficient server-side authorization checks, allowing authenticated low-privileged users to send crafted HTTP requests that can reboot or shut down the affected system. This is an authorization bypass vulnerability where the server fails to validate proper privileges before executing privileged operations.

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.
-
Confirm Cisco NFVIS is runningIdentify if the system is running Cisco Network Functions Virtualization Infrastructure. Check for NFVIS processes, services, or known installation paths. On the CLI, run 'show version' or check system information to verify the NFVIS platform.Affected if The system is confirmed to be running Cisco NFVIS (any version)
-
Verify web-based management interface is enabledCheck if the NFVIS web-based management interface (typically accessible on HTTPS port 443 or configured management ports) is active and accessible. Query the NFVIS configuration for management interface status or attempt a local connection to the management interface port.Affected if The NFVIS web management interface is enabled and network-accessible
-
Identify exposed management portsReview firewall rules, network configuration, and listening services to determine if NFVIS management ports are exposed beyond the intended management network. Use 'netstat' or 'show ip interface' commands on the NFVIS host.Affected if Management ports are exposed to untrusted networks or the internet
-
Review user access logs for low-privileged accountsExamine NFVIS authentication and access logs for activity from user accounts with standard or limited privileges. Look for authentication events and privileged operation requests from these accounts.Affected if Low-privileged authenticated users have accessed the web management interface
-
Check for unexpected system commands in logsSearch NFVIS logs (via web UI logs, system logs, or CLI 'show logging') for unusual reboot, shutdown, or system command requests that may indicate exploitation attempts.Affected if Logs show reboot/shutdown commands issued by low-privileged users
If the system runs Cisco NFVIS with the web management interface enabled and low-privileged users can access it, the environment is potentially affected by CVE-2018-0459.

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 dataApply the relevant Cisco security patch for CVE-2018-0459. Until patched, monitor user activity closely and restrict web management interface access to only necessary personnel using network segmentation.
