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
An issue was discovered in WatchGuard EPDR 8.0.21.0002. Due to a weak implementation of a password check, it is possible to obtain credentials to access the management console as a non-privileged user.

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 confidence

WatchGuard EPDR 8.0.21.0002 contains a weak password check implementation that allows a non-privileged user to obtain credentials and access the management console, effectively bypassing authentication controls.

MitigationApply the vendor-supplied patch or update to a patched version of WatchGuard EPDR that addresses the weak password check vulnerability.

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 installed WatchGuard EPDR/EPP/EDR firmware version
    Access the management console or use the product's system information interface to determine the current firmware version
    Affected if The installed version is earlier than 8.00.22.0010
  2. Confirm product type matches vulnerable variants
    Verify that the installed product is one of: WatchGuard EPP Firmware, WatchGuard EDR Firmware, WatchGuard Epdr Firmware, or WatchGuard Panda Ad360 Firmware
    Affected if The product is any of these four variants with version < 8.00.22.0010
  3. Determine if management console is exposed
    Check whether the WatchGuard management console interface is accessible over the network or locally
    Affected if The management console is accessible and the version is < 8.00.22.0010, the weak password check flaw may be exploitable

A user is affected if their WatchGuard EPDR/EPP/EDR or Panda Ad360 installation shows a firmware version lower than 8.00.22.0010.
