CVE-2018-0324
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 CLI of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, high-privileged, local attacker to perform a command injection attack. The vulnerability is due to insufficient input validation of command parameters in the CLI parser. An attacker could exploit this vulnerability by invoking a vulnerable CLI command with crafted malicious parameters. An exploit could allow the attacker to execute arbitrary commands with a non-root user account on the underlying Linux operating system of the affected device. Cisco Bug IDs: CSCvi09723.
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 confidenceA command injection vulnerability exists in the CLI parser of Cisco Enterprise NFV Infrastructure Software (NFVIS) due to insufficient input validation of command parameters. An authenticated high-privileged local attacker can exploit this by invoking vulnerable CLI commands with crafted malicious parameters, allowing execution of arbitrary commands on the underlying Linux OS with non-root user privileges.

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 installedRun 'show version' in the CLI or check system boot logs to verify the system is running Cisco Enterprise NFV Infrastructure SoftwareAffected if System is running Cisco NFVIS
-
Check NFVIS version numberExecute 'show version' command in the CLI or inspect system information to obtain the exact NFVIS versionAffected if Version equals 3.6.1, 3.6.2, or 3.7.1 exactly
-
Verify CLI interface is accessibleAttempt to access the NFVIS CLI or check network configuration to confirm CLI management interface is enabled and reachableAffected if CLI interface is accessible to authenticated users
-
Identify authenticated high-privileged usersReview local user accounts and their privilege levels using 'show user' or similar administrative commandsAffected if High-privileged local user accounts exist with CLI access
Environment is affected if running Cisco NFVIS version 3.6.1, 3.6.2, or 3.7.1 with CLI accessible to authenticated high-privileged users.

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 Cisco vendor patch for CSCvi09723 to remediate the input validation flaw in the CLI parser. Until the patch is available, restrict CLI access to only absolutely necessary high-privileged users and monitor for suspicious command activity.
