CVE-2019-1624
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 vManage web-based UI (Web UI) in the Cisco SD-WAN Solution could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by authenticating to the device and submitting crafted input to the vManage Web UI. A successful exploit could allow the attacker to execute commands with root privileges.
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 in the vManage web-based UI of Cisco SD-WAN allows authenticated remote attackers to inject arbitrary operating system commands through insufficiently validated input fields. The injected commands execute with root privileges on the underlying system, enabling full compromise of the vManage device.

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 vManage is running on the systemIdentify if the Cisco SD-WAN vManage component is installed. This is typically a virtual appliance or hardware device that provides the SD-WAN management plane. Check system inventory, running processes, or device documentation to confirm vManage presence.Affected if vManage software is installed and running on the system
-
Determine the installed vManage versionAccess the vManage web UI and navigate to the Administration section, or use the CLI command 'show version' on the vManage device to retrieve the software version number. Compare this version against the affected range of versions prior to 18.4.0.Affected if The installed version is any release prior to 18.4.0 (for example, 18.3.x, 18.2.x, earlier releases)
-
Verify the vManage web-based UI is accessibleAttempt to access the vManage web interface via HTTPS on the management IP address. Confirm the web service is listening and reachable on port 443 or the configured web port.Affected if The vManage web UI is reachable and accepts connections
-
Confirm authentication is enabled on the web UIVerify that the vManage web UI requires valid administrator credentials. Attempt an unauthenticated request or check the authentication settings in the Administration > User Management section of the web interface.Affected if Unauthenticated or authenticated users can access input fields in the vManage web interface
A system is affected if it runs any Cisco SD-WAN vManage version prior to 18.4.0 and has the web-based UI accessible to users who can submit input.

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 data18.4.0
Apply the Cisco security patch for CVE-2019-1624. Until patched, restrict access to the vManage web UI to trusted administrators only and implement network segmentation to limit exposure.
