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
InHand Networks IR615 Router's Versions 2.3.0.r4724 and 2.3.0.r4870 are vulnerable to an attacker using a ping tool to inject commands into the device. This may allow the attacker to remotely run commands on behalf of the device.

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 · moderate confidence

The InHand Networks IR615 Router versions 2.3.0.r4724 and 2.3.0.r4870 contain a command injection vulnerability in the ping functionality. The ping tool fails to properly sanitize user-supplied input, allowing an attacker to inject shell commands that execute with the device's privileges.

MitigationIf a patched firmware version is available from InHand Networks, upgrade the device immediately. Otherwise, restrict network access to the router's management interface using firewalls or VLANs, and disable remote administration if not required.

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
    Identify the InHand Networks IR615 Router in your environment through device discovery, network inventory, or web interface login
    Affected if The device is not an IR615 Router
  2. Check firmware version
    Access the router's web management interface or CLI and locate the firmware version information, typically found in System Status, Device Info, or About sections
    Affected if The installed firmware version is exactly 2.3.0.r4724 or 2.3.0.r4870
  3. Verify ping feature accessibility
    Determine if the ping diagnostic tool is accessible through the web interface, CLI, or API endpoint. Check if the user role assigned to accounts includes access to network diagnostic functions
    Affected if The ping functionality is exposed and accessible to any user or unauthenticated actor
  4. Assess management interface exposure
    Review network configuration to determine if the router's web management interface is reachable from untrusted networks or the internet
    Affected if The management interface is directly exposed to the internet or untrusted LAN segments without firewall protection

You are affected if you have an IR615 Router running firmware version 2.3.0.r4724 or 2.3.0.r4870 with the ping feature accessible to an attacker who can reach the management interface.
