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 Linear eMerge e3-Series through version 1.00-07 is vulnerable to an OS command injection vulnerability. A remote and unauthenticated attacker can execute arbitrary OS commands via the login_id parameter when invoking the forgot_password functionality over HTTP.

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

The Linear eMerge e3-Series access control panels through version 1.00-07 contain a critical OS command injection vulnerability in the forgot_password functionality. An unauthenticated remote attacker can execute arbitrary operating system commands by injecting malicious input through the login_id parameter over HTTP.

MitigationApply vendor firmware patches immediately when available; meanwhile, disable external access to the forgot_password endpoint via network segmentation or firewall rules, as this is a critical unauthenticated command injection in a physical security device.

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
    Access the device web interface or check system documentation to identify if the device is a Linear eMerge e3-Series access control system. Look for model identification in the web UI footer or system info page.
    Affected if The device is a Linear eMerge e3-Series system.
  2. Check firmware version
    Locate the firmware or software version information in the device web interface (typically under System, About, or Status pages). Compare the installed version to the affected range up to and including version 1.00-07.
    Affected if The installed firmware version is 1.00-07 or earlier.
  3. Verify forgot_password endpoint exposure
    Attempt to access the forgot_password page via HTTP (e.g., GET request to /forgot_password or similar path). Check if the endpoint responds and accepts the login_id parameter.
    Affected if The forgot_password endpoint is accessible and accepts the login_id parameter via HTTP.
  4. Assess network accessibility
    Determine if the device HTTP interface is reachable from untrusted networks (such as the public internet) by checking firewall rules, NAT configurations, or network access lists.
    Affected if The device HTTP interface is accessible from untrusted or external networks without proper network segmentation.

A user is affected if they operate a Linear eMerge e3-Series device with firmware version 1.00-07 or earlier, where the forgot_password endpoint is exposed to untrusted networks.
