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
Fujitsu Real-time Video Transmission Gear "IP series" use hard-coded credentials, which may allow a remote unauthenticated attacker to initialize or reboot the products, and as a result, terminate the video transmission. Affected products and versions are as follows: IP-HE950E firmware versions V01L001 to V01L053, IP-HE950D firmware versions V01L001 to V01L053, IP-HE900E firmware versions V01L001 to V01L010, IP-HE900D firmware versions V01L001 to V01L004, IP-900E / IP-920E firmware versions V01L001 to V02L061, IP-900D / IP-900ⅡD / IP-920D firmware versions V01L001 to V02L061, IP-90 firmware versions V01L001 to V01L013, and IP-9610 firmware versions V01L001 to V02L007.

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

Fujitsu IP series video transmission devices contain hard-coded credentials embedded in the firmware. A remote unauthenticated attacker can use these credentials to access administrative functions and trigger device initialization or reboot, resulting in denial of service for video transmission.

MitigationUpdate firmware to versions beyond the vulnerable ranges cited. If updates are unavailable, restrict network access to management interfaces via firewall rules or VLAN isolation to prevent unauthorized external access.

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 the device model
    Locate the device label on the physical unit or access the web administration interface to confirm the exact model number (e.g., Ip He950e, Ip 900e, Ip 920e, etc.)
    Affected if The model is one of the following: Ip He950e, Ip He950d, Ip He900e, Ip He900d, Ip 900e, Ip 920e, Ip 900d, or Ip 900iid
  2. Check the installed firmware version
    Access the device web interface and navigate to the System Information or Firmware section to view the current firmware version, or use SNMP or the manufacturer-provided management tool if available
    Affected if The firmware version cannot be determined or is not displayed
  3. Compare firmware version to affected ranges
    Compare the installed firmware version against the vulnerable ranges: Ip He950e/d: v01l001 to v01l053; Ip He900e: v01l001 to v01l010; Ip He900d: v01l001 to v01l004; Ip 900e/920e/900d/900iid: v01l001 to v02l061
    Affected if The installed version falls within or cannot be determined to be outside the listed vulnerable ranges for your specific model
  4. Verify network exposure of management interface
    Check if the device management interface (HTTP/HTTPS ports typically 80/443 or manufacturer-specific ports) is accessible from untrusted network segments or the public internet by reviewing firewall rules, VLAN configuration, or performing a port scan from an external source
    Affected if The management interface is exposed to untrusted networks or the internet without network-level access controls

The device is affected if it is a Fujitsu IP series model (He950e/d, He900e/d, 900e, 920e, 900d, or 900iid) and its firmware version falls within the vulnerable ranges listed, especially if the management interface is network-accessible to untrusted parties.

Mitigation

Update firmware to versions beyond the vulnerable ranges cited. If updates are unavailable, restrict network access to management interfaces via firewall rules or VLAN isolation to prevent unauthorized external access.
