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
Panasonic P99 devices through 2020-04-10 have Incorrect Access Control. NOTE: the vendor states that all affected products are at "End-of-software-support."

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 · low confidence

Panasonic P99 devices through 2020-04-10 contain an Incorrect Access Control vulnerability. This type of flaw typically means the device fails to properly enforce authorization checks, potentially allowing unauthorized users to access sensitive functionality or administrative features. The critical CVSS score of 9.8 suggests the vulnerability can be exploited remotely without authentication.

MitigationSince Panasonic has declared these devices at end-of-software-support with no patches forthcoming, organizations should immediately isolate affected devices via network segmentation, implement strict firewall/ACL controls, and plan for device replacement with supported alternatives.

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 Panasonic P99 devices on your network
    Scan your network inventory or use network discovery tools to locate Panasonic P99 devices. Check device labels, management interfaces, or DHCP logs for these specific devices.
    Affected if Panasonic P99 devices are present in your environment
  2. Determine the firmware version installed
    Access the device administration interface or check via SNMP/management protocol. Look for a version date or build number. Compare against the 2020-04-10 cutoff.
    Affected if Firmware version date is on or before 2020-04-10
  3. Check network exposure of the device
    Verify if the device management interface is accessible from untrusted networks or the internet. Review firewall rules, ACLs, and NAT configurations affecting the device.
    Affected if The device management interface is reachable from outside the local trusted network
  4. Assess authentication configuration
    Review the device access control settings to confirm whether authentication is properly enforced on administrative functions and API endpoints.
    Affected if Authentication is missing, disabled, or improperly enforced on sensitive functions

Your environment is affected if you have Panasonic P99 devices running firmware dated 2020-04-10 or earlier that are network-accessible without proper authentication controls in place.

Interim mitigation

Since Panasonic has declared these devices at end-of-software-support with no patches forthcoming, organizations should immediately isolate affected devices via network segmentation, implement strict firewall/ACL controls, and plan for device replacement with supported alternatives.

Recommended fix High confidence
  1. This vulnerability has no available remediation from the vendor.
  2. Panasonic has stated that all affected products are at 'End-of-software-support' and will not receive firmware updates.
  3. If the device is still in production use, consider replacing it with a supported model.
  4. If the device cannot be replaced, implement network-based controls such as restricting network access to the device and placing it behind a firewall with strict access control lists.
  5. Monitor the mobile.panasonic.com reference source for any future disclosures or workaround guidance.
