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 · unedited
Pure Storage FlashArray products running Purity//FA 6.2.0 - 6.2.3, 6.1.0 - 6.1.12, 6.0.0 - 6.0.8, 5.3.0 - 5.3.17, 5.2.x and prior Purity//FA releases, and Pure Storage FlashBlade products running Purity//FB 3.3.0, 3.2.0 - 3.2.4, 3.1.0 - 3.1.12, 3.0.x and prior Purity//FB releases are vulnerable to a privilege escalation via the manipulation of Python environment variables which can be exploited by a logged-in user to escape a restricted shell to an unrestricted shell with root privileges. No other Pure Storage products or services are affected. Remediation is available from Pure Storage via a self-serve “opt-in” patch, manual patch application or a software upgrade to an unaffected version of Purity software.

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 confidence

Pure Storage FlashArray and FlashBlade products contain a privilege escalation vulnerability where authenticated users can manipulate Python environment variables to escape a restricted shell and gain root-level privileges. This allows any logged-in user to escalate from their constrained shell access to full unrestricted administrative access.

MitigationApply the self-serve opt-in patch, manually apply the vendor patch, or upgrade to an unaffected version of Purity//FA or Purity//FB software as specified in Pure Storage advisory.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Purity//fa version
    Access the Pure Storage FlashArray management interface or use the Pure CLI (`purectl version` or `purefa get -s`) to retrieve the installed Purity//fa software version
    Affected if The version falls within < 5.3.18 OR >= 6.0.0 and < 6.0.9 OR >= 6.1.0 and < 6.1.13 OR >= 6.2.0 and < 6.2.4
  2. Identify Purity//fb version
    Access the Pure Storage FlashBlade management interface or use the Pure CLI (`pureblades version` or `purefb get -s`) to retrieve the installed Purity//fb software version
    Affected if The version falls within < 3.1.13 OR >= 3.2.0 and < 3.2.5 OR >= 3.3.0 and < 3.3.1
  3. Confirm authenticated user access exists
    Review user accounts that have shell access to the Pure Storage array. Check if any non-administrative users have login credentials for the restricted shell environment
    Affected if Any authenticated users exist with access to the restricted shell on the affected device
  4. Verify Python environment variable manipulation is possible
    From the restricted shell session, attempt to set or modify Python-related environment variables such as PYTHONPATH, PYTHONHOME, or PYTHONSTARTUP. If the restricted shell permits modification of these variables, the condition is met
    Affected if The restricted shell allows manipulation of Python environment variables without blocking such modifications

The environment is affected if the installed Purity//fa or Purity//fb version matches any of the affected version ranges AND authenticated users have access to the restricted shell where Python environment variables can be manipulated.

Upgrade available Upgrade to 3.1.13 / 3.2.5 / 3.3.1 or later
Fixed in 3.1.133.2.53.3.1
Interim mitigation

Apply the self-serve opt-in patch, manually apply the vendor patch, or upgrade to an unaffected version of Purity//FA or Purity//FB software as specified in Pure Storage advisory.

Recommended fix High confidence

Purity//FA: upgrade to 5.3.18, 6.0.9, 6.1.13, or 6.2.4 (or later); Purity//FB: upgrade to 3.1.13, 3.2.5, or 3.3.1 (or later)

  1. 1. Identify the current Purity//FA or Purity//FB version running on your FlashArray or FlashBlade device.
  2. 2. For Purity//FA: If running version 5.2.x or prior, upgrade to 5.3.18 or later. If running 5.3.0-5.3.17, upgrade to 5.3.18. If running 6.0.0-6.0.8, upgrade to 6.0.9 or later. If running 6.1.0-6.1.12, upgrade to 6.1.13 or later. If running 6.2.0-6.2.3, upgrade to 6.2.4 or later.
  3. 3. For Purity//FB: If running version 3.0.x or prior, upgrade to 3.1.13 or later. If running 3.1.0-3.1.12, upgrade to 3.1.13. If running 3.2.0-3.2.4, upgrade to 3.2.5. If running 3.3.0, upgrade to 3.3.1.
  4. 4. Contact Pure Storage support to obtain the self-serve opt-in patch, manual patch, or upgrade package from support.purestorage.com.
  5. 5. Schedule maintenance window as upgrade may require downtime.
  6. 6. Apply the patch or perform the upgrade following Pure Storage documentation.
  7. 7. Verify the version has been updated and the vulnerability is resolved.
Caveat Upgrades may require downtime; test in non-production environment first; verify compatibility with existing integrations
