CVE-2018-15380
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 cluster service manager of Cisco HyperFlex Software could allow an unauthenticated, adjacent attacker to execute commands as the root user. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by connecting to the cluster service manager and injecting commands into the bound process. A successful exploit could allow the attacker to run commands on the affected host as the root user. This vulnerability affects Cisco HyperFlex Software releases prior to 3.5(2a).
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 confidenceCommand injection vulnerability in Cisco HyperFlex Software's cluster service manager allows an unauthenticated, adjacent attacker to inject and execute arbitrary commands as root due to insufficient input validation on the bound process.

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 Cisco HyperFlex installationCheck if Cisco HyperFlex Hx Data Platform is deployed in the environment by querying the management interface or using the HyperFlex CLI tool (stcli) if availableAffected if The system does not have Cisco HyperFlex Hx Data Platform installed, the check is not applicable
-
Check Hx Data Platform versionUse the stcli command 'stcli cluster version' or check the HyperFlex management UI under the cluster information section to retrieve the installed Hx Data Platform version numberAffected if The installed version matches 3.0(1a) or 3.5(1a) exactly, indicating the vulnerable versions are present
-
Verify cluster service manager is enabledConfirm the cluster service manager process is running and bound to a network interface. This can be checked via HyperFlex management interfaces or by reviewing the running services on the HyperFlex cluster nodesAffected if The cluster service manager is active and accessible on the network, making the command injection surface exposed
-
Confirm adjacency access to cluster service managerDetermine if the cluster service manager listener is bound to an interface accessible from the adjacent network segment rather than localhost onlyAffected if The service is reachable from adjacent network segments, allowing an unauthenticated adjacent attacker to reach the vulnerable endpoint
The environment is affected if Cisco HyperFlex Hx Data Platform version 3.0(1a) or 3.5(1a) is installed AND the cluster service manager is accessible from the network.
