CVE-2019-18577
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 · uneditedDell EMC XtremIO XMS versions prior to 6.3.0 contain an incorrect permission assignment vulnerability. A malicious local user with XtremIO xinstall privileges may exploit this vulnerability to gain root access.
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 local privilege escalation vulnerability in Dell EMC XtremIO XMS versions prior to 6.3.0 allows users with XtremIO xinstall privileges to gain root access due to an incorrect permission assignment.

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 XtremIO XMS is installedIdentify if Dell EMC XtremIO XMS (XtremIO Management Server) software is present in the environment. Check system inventory or installed software packages for 'XtremIO' or 'XMS' components.Affected if XtremIO XMS software is not present in the environment - not affected
-
Determine installed XMS versionLocate and read the XMS version information. This is typically accessible through the XMS administrative interface, system documentation, or version check commands specific to the XtremIO management software.Affected if The installed version is 6.3.0 or later - not affected. The version is below 6.3.0 - potentially affected
-
Verify xinstall user or privilege existsCheck for the presence of users with xinstall privileges in the XMS system. This user or privilege level is specific to XtremIO XMS for installation operations.Affected if No xinstall user or privilege exists - the specific exploitation vector is not present. The xinstall privilege exists on versions below 6.3.0 - likely affected
-
Inspect system permissions on critical filesReview file permissions on system binaries or configuration files that the xinstall user would access. Look for permission configurations that allow a user with xinstall privileges to modify or execute files that should be restricted to root.Affected if Permissions allow modification or execution by non-root users with elevated privileges - confirmed vulnerable configuration
A defender is affected if Dell EMC XtremIO XMS is installed with a version prior to 6.3.0 and the xinstall privilege exists in the environment.
