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
Snap One Wattbox WB-300-IP-3 versions WB10.9a17 and prior could bypass the brute force protection, allowing multiple attempts to force a login.

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

The Wattbox WB-300-IP-3 contains an authentication bypass vulnerability where the brute force protection mechanism can be circumvented. This allows attackers to make unlimited login attempts without triggering account lockout, enabling automated credential stuffing or brute force attacks against the device's admin interface.

MitigationApply the vendor firmware update that addresses CVE-2023-24020. If no patch is available, restrict network access to the management interface using firewall rules or VPN, and monitor for suspicious authentication activity.

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. Confirm device model is Wattbox WB-300-IP-3
    Access the device's web interface or check the device label/physics to verify the exact model number is WB-300-IP-3
    Affected if The device is not a Wattbox WB-300-IP-3 model
  2. Check installed firmware version
    Log into the Wattbox admin interface and navigate to the firmware or status page to view the current firmware version, or check via SNMP or the device's API if available
    Affected if Firmware version is wb10.9a17 or lower (any version <= wb10.9a17)
  3. Verify admin interface network exposure
    Check network configuration to determine if the device's web admin interface (typically ports 80/443 or custom HTTP/HTTPS ports) is accessible from untrusted networks such as the public internet or less-trusted VLANs
    Affected if The admin interface is reachable from networks outside the trusted management network
  4. Review authentication logs for brute force patterns
    Examine device logs, syslog exports, or SIEM/monitoring systems for signs of repeated failed login attempts from the same source IP, or successful logins from unexpected locations
    Affected if Logs show high-volume authentication attempts from a single source or patterns indicative of automated credential stuffing without account lockout triggering

A user is affected if they have a Wattbox WB-300-IP-3 running firmware version wb10.9a17 or lower, with its admin interface network-accessible and no compensating controls blocking the attack vector.
