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
Versions of INEA ME RTU firmware prior to 3.36 are vulnerable to OS command injection, which could allow an attacker to remotely execute arbitrary code.

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

OS command injection vulnerability in INEA ME RTU firmware versions prior to 3.36 allows remote attackers to inject and execute arbitrary operating system commands through the device interface, potentially compromising the entire RTU device.

MitigationUpgrade INEA ME RTU firmware to version 3.36 or later to eliminate the command injection vector. If immediate patching is not possible, network segmentation and restricting access to the RTU management interfaces should be implemented as compensating controls.

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 INEA ME RTU firmware version
    Access the device management interface or system information page, or use the device's CLI command to display firmware version (commonly 'show version' or similar). For web interfaces, look in the System > About or Device Information section.
    Affected if The displayed firmware version is any version prior to 3.36 (for example, 3.35, 3.30, etc.)
  2. Confirm the device model
    Verify that the affected device is specifically an INEA ME RTU (Remote Terminal Unit) model. Check the device label, web interface header, or system information page for the exact model name.
    Affected if The device is confirmed as an INEA ME RTU and the firmware version is below 3.36
  3. Assess network exposure of management interface
    Check if the RTU management or device interface is accessible from network segments outside the trusted internal network. Review firewall rules, NAT configurations, and access control lists that govern access to the device.
    Affected if The device interface is reachable from untrusted networks or the internet, enabling remote attackers to reach the command injection vector
  4. Verify if web-based or API interface is enabled
    Determine whether the device's web interface, API, or other user-facing interface that accepts input is enabled and operational. This is the vector through which command injection occurs.
    Affected if The device interface (web UI, API endpoint, or similar input-accepting service) is enabled and accessible

If the installed INEA ME RTU firmware version is below 3.36 and the device interface is network-accessible, the environment is vulnerable to command injection exploitation.

dbcve · scoped
Upgrade available Upgrade to 3.36 or later
Fixed in 3.36
Interim mitigation

Upgrade INEA ME RTU firmware to version 3.36 or later to eliminate the command injection vector. If immediate patching is not possible, network segmentation and restricting access to the RTU management interfaces should be implemented as compensating controls.

Recommended fix High confidence

firmware version 3.36

  1. Identify the current firmware version of the INEA ME RTU device
  2. Obtain firmware version 3.36 or later from the official INEA download repository
  3. Follow the manufacturer's official firmware upgrade procedure for the ME RTU device
  4. Verify the firmware upgrade was successful by confirming the running firmware version is 3.36 or later
