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
The web console of FUJITSU Network IPCOM series (IPCOM EX2 IN(3200, 3500), IPCOM EX2 LB(1100, 3200, 3500), IPCOM EX2 SC(1100, 3200, 3500), IPCOM EX2 NW(1100, 3200, 3500), IPCOM EX2 DC, IPCOM EX2 DC, IPCOM EX IN(2300, 2500, 2700), IPCOM EX LB(1100, 1300, 2300, 2500, 2700), IPCOM EX SC(1100, 1300, 2300, 2500, 2700), and IPCOM EX NW(1100, 1300, 2300, 2500, 2700)) allows a remote attacker to execute an arbitrary OS command via unspecified vectors.

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

Command injection vulnerability in the web console of Fujitsu IPCOM network appliances allowing remote attackers to execute arbitrary OS commands. This is a critical flaw that enables complete device compromise without authentication.

MitigationRestrict network access to management interfaces immediately. Contact Fujitsu for available firmware patches and apply them to all affected devices. If no patch available, consider network segmentation or device replacement.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Fujitsu IPCOM device model
    Access the device web console or check the device label/serial number to confirm the exact model (e.g., Ipcom Ex2 Nw 1100, Sc 3500, Lb 3200)
    Affected if The device is a Fujitsu Ipcom Ex2 series model (Nw, Sc, or Lb variants)
  2. Check the installed firmware version
    Log into the device web interface or CLI and locate the firmware version information, typically found in System, Status, or About sections
    Affected if The firmware version is earlier than v01l05_nf0501 (for example, v01l04 or earlier)
  3. Verify the web console is enabled and accessible
    Confirm that the HTTP/HTTPS web management interface is enabled and reachable on the device network
    Affected if The web console is exposed on the network (this is required for the command injection to be exploitable)
  4. Confirm the device falls within affected version range
    Cross-reference the identified model and firmware version against the affected product list provided in the CVE
    Affected if The device is a listed model (Nw 1100, Nw 3500, Nw 3200, Sc 1100, Sc 3500, Sc 3200, Lb 1100, Lb 3500) with firmware version less than v01l05_nf0501

You are affected if you have a Fujitsu Ipcom Ex2 series device (Nw, Sc, or Lb model) running firmware version earlier than v01l05_nf0501 with the web console enabled and accessible on your network.

Mitigation

Restrict network access to management interfaces immediately. Contact Fujitsu for available firmware patches and apply them to all affected devices. If no patch available, consider network segmentation or device replacement.

Recommended fix High confidence

v01l05_nf0501

  1. Identify the exact IPCOM EX2 model (NW, SC, or LB series) and current firmware version via the web console or administrative interface
  2. Navigate to Fujitsu support website (www.fujitsu.com) or the vendor's firmware download page
  3. Download firmware version v01l05_nf0501 or later for your specific model
  4. Backup the current device configuration through the web console
  5. Access the firmware upgrade section in the device administration interface
  6. Upload and apply the v01l05_nf0501 firmware file
  7. Verify the upgrade was successful by checking the new firmware version in the web console
  8. Restore the configuration if needed and verify normal operation
