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 unauthenticated attacker can perform a null pointer dereference in the DHIP Service (UDP port 37810). This vulnerability has been resolved in firmware version 2.800.0000000.8.R.20241111.

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

An unauthenticated remote attacker can trigger a null pointer dereference in the DHIP Service listening on UDP port 37810, causing a denial of service condition. This is a memory corruption vulnerability stemming from improper null pointer validation in the firmware.

MitigationApply firmware version 2.800.0000000.8.R.20241111 or later to all affected devices. If immediate patching is not possible, consider network segmentation to limit access to UDP port 37810 from untrusted sources.

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 if DHIP service is running on UDP port 37810
    Run 'netstat -anu | grep 37810' or 'ss -uan | grep 37810' to check for listening UDP socket on port 37810. Alternatively, use a port scanner like 'nmap -sU -p 37810 <target>' to probe the port.
    Affected if UDP port 37810 is open and the DHIP service is responding to queries
  2. Verify firmware version of the device
    Access the device management interface or use SNMP/WEB/REST APIs provided by the device vendor to retrieve the current firmware version. Compare against the fixed version 2.800.0000000.8.R.20241111.
    Affected if Firmware version is older than 2.800.0000000.8.R.20241111 or cannot be determined
  3. Check network exposure of UDP port 37810
    Review firewall rules and network ACLs to determine if UDP port 37810 is accessible from untrusted network segments or the public internet. Use 'iptables -L -n' or equivalent to list current rules.
    Affected if UDP port 37810 is accessible from untrusted networks without firewall filtering
  4. Confirm DHIP service responds to malformed packets
    Send a crafted UDP packet to port 37810 using a tool like 'nc -u' or 'python -c' with malformed/incomplete data and observe if the service crashes or becomes unresponsive.
    Affected if Service crashes, becomes unresponsive, or generates error logs indicating null pointer dereference after receiving malformed UDP payload

A system is affected if it runs DHIP service on UDP port 37810 with firmware older than 2.800.0000000.8.R.20241111 AND the port is accessible from untrusted network segments.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply firmware version 2.800.0000000.8.R.20241111 or later to all affected devices. If immediate patching is not possible, consider network segmentation to limit access to UDP port 37810 from untrusted sources.

Recommended fix Moderate confidence

2.800.0000000.8.R.20241111

  1. Identify the specific device model that runs the DHIP Service on UDP port 37810
  2. Consult the device vendor's firmware download page or support portal
  3. Download firmware version 2.800.0000000.8.R.20241111 or later
  4. Review the vendor's firmware upgrade instructions for the specific device model
  5. Upload and apply the firmware update following the vendor's recommended procedure
  6. Verify the firmware version has been successfully applied after reboot
  7. Confirm the DHIP Service (UDP port 37810) is functioning normally
