CVE-2018-0344
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 dashboard for the configuration and management service of the Cisco SD-WAN Solution could allow an authenticated, remote attacker to inject and execute arbitrary commands with vmanage user privileges on an affected system. The vulnerability is due to insufficient input validation of data parameters for certain fields in the affected solution. An attacker could exploit this vulnerability by configuring a malicious username on the login page of the affected solution. A successful exploit could allow the attacker to inject and execute arbitrary commands with vmanage user privileges on an affected system. This vulnerability affects the following Cisco products if they are running a release of the Cisco SD-WAN Solution prior to Release 18.3.0: vBond Orchestrator Software, vEdge 100 Series Routers, vEdge 1000 Series Routers, vEdge 2000 Series Routers, vEdge 5000 Series Routers, vEdge Cloud Router Platform, vManage Network Management Software, vSmart Controller Software. Cisco Bug IDs: CSCvi69974.

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.
-
Identify installed SD-WAN componentLog into the vManage web UI or use CLI to determine which Cisco SD-WAN component is running. Check the system information or version page for product name (Vbond Orchestrator, Vedge Plus, Vedge Pro, Vmanage Network Management, Vsmart Controller, or Vedge 100/100b/100m).Affected if The system is running any of the listed affected products with all versions, or Vedge 100/100b/100m with firmware version below 18.3.0
-
Check Vedge firmware versionFor Vedge devices, access the device CLI and run the command 'show version' or access vManage to view device inventory and firmware version details.Affected if The Vedge firmware version is lower than 18.3.0 for models 100, 100b, or 100m
-
Verify vManage login interface accessibilityConfirm the vManage web interface is accessible by attempting to reach the login page via HTTPS on the management IP address (default port 8443 or 443).Affected if The vManage login page is exposed and reachable on the network
-
Confirm authentication is enabledCheck the vManage system settings or authentication configuration to verify that user authentication is enabled on the login page.Affected if User authentication is enabled on the vManage login page, which is the default configuration
A system is affected if it runs any Cisco SD-WAN component from the affected product list (all versions for most products, or Vedge firmware below 18.3.0) and has the vManage login interface accessible with authentication enabled.
