CVE-2019-5396
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 remote authentication bypass vulnerability was discovered in HPE 3PAR Service Processor version(s): prior to 5.0.5.1.
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 · moderate confidenceThis is a critical remote authentication bypass vulnerability in HPE 3PAR Service Processor that allows unauthenticated remote attackers to circumvent authentication mechanisms and gain unauthorized access to the system. The vulnerability affects all versions prior to 5.0.5.1.

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.
-
Check HPE 3PAR Service Processor firmware versionLog into the HPE 3PAR Service Processor management interface or access via SSH and run the version command (e.g., `version` or `showsys` command from the 3PAR CLI). Locate the firmware version displayed in the output.Affected if The displayed firmware version is lower than 5.0.5.1 (for example, 5.0.4.0, 4.x.x.x, etc.)
-
Verify Service Processor component versionFrom the Service Processor command line, check the Service Processor component version using `sp version` or `showsp` command if available. This displays the specific Service Processor firmware version.Affected if The Service Processor firmware version shown is below 5.0.5.1
-
Check via SSMC or management GUIAccess the HPE System Storefront Management Console (SSMC) or the 3PAR management GUI, navigate to the Service Processor settings or system information section, and note the reported firmware version.Affected if The firmware version shown in the GUI is earlier than 5.0.5.1
-
Confirm Service Processor is network accessibleVerify that the Service Processor management interface is exposed to the network (check if port 22/SSH or management GUI ports are reachable from untrusted networks). This is required for the vulnerability to be exploitable.Affected if The Service Processor is network-accessible and the version is below 5.0.5.1
A system is affected if the HPE 3PAR Service Processor firmware version is below 5.0.5.1 and the management interface is network-accessible, allowing remote unauthenticated attackers to bypass authentication.
