CVE-2021-26588
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 potential security vulnerability has been identified in HPE 3PAR StoreServ, HPE Primera Storage and HPE Alletra 9000 Storage array firmware. An unauthenticated user could remotely exploit the low complexity issue to execute code as administrator. This vulnerability impacts completely the confidentiality, integrity, availability of the array. HPE has made the following software updates and mitigation information to resolve the vulnerability in 3PAR, Primera and Alletra 9000 firmware.
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 confidenceThis vulnerability allows unauthenticated remote attackers to execute code as administrator on affected HPE storage array firmware (3PAR StoreServ, Primera, Alletra 9000) due to an unspecified security flaw, with low exploitation complexity and critical CVSS 9.8 rating completely compromising confidentiality, integrity, and availability.

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 the HPE storage array modelLog into the storage system CLI or check the physical label/sticker to determine if the device is a 3PAR StoreServ, Primera (630, 650, or 670), or Alletra 9000 (9060 or 9080) modelAffected if The device is not one of these models, the check does not apply
-
Determine the installed 3PAR OS versionAccess the 3PAR CLI or management interface and run 'showversion' or navigate to System > Overview to retrieve the exact OS firmware versionAffected if The installed version matches exactly 3.3.1_mp5_p156, 3.3.1_mu1, 3.3.1_mu2_p157, or 3.3.2_ga_p_01
-
Determine the installed Primera firmware versionAccess the Primera management GUI or CLI and check the firmware version under System > Health or using 'showversion' commandAffected if The installed firmware version is between 4.0.0 and 4.3.3 inclusive (for Primera 630, 650, or 670)
-
Determine the installed Alletra 9000 firmware versionAccess the Alletra 9000 management interface and check the firmware version under System Overview or using 'showversion'Affected if The installed firmware version is between 9.3.0 and 9.4.0 inclusive (for Alletra 9060 or 9080)
The environment is affected if it runs any of the listed HPE storage models (3PAR, Primera 630/650/670, or Alletra 9060/9080) with a firmware version matching the specific affected ranges provided.
