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
Command injection vulnerability in the operating system in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2 through the 'GetDNS()', 'CheckPing()' and 'TraceRoute()' functions.

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 Circutor SGE-PLC1000/SGE-PLC50 devices allows remote attackers to execute arbitrary OS commands through the GetDNS(), CheckPing(), and TraceRoute() functions in firmware v9.0.2 through later versions. These network diagnostic functions fail to properly sanitize input, enabling OS command injection.

MitigationApply vendor firmware patch when available; if no patch exists, isolate affected devices on a dedicated network segment and restrict access to these functions via firewall rules or access controls.

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 Circutor device by checking the web interface header, device label, or SNMP/sysinfo output. Look for SGE-PLC1000 or SGE-PLC50 identifiers
    Affected if Device is not an SGE-PLC1000 or SGE-PLC50 model
  2. Retrieve firmware version
    Access the device web interface System Settings or Status page, or query the device API for firmware version information. Compare the version number to 9.0.2
    Affected if Firmware version is 9.0.2 or later
  3. Locate network diagnostic functions
    Navigate the device web interface to find the GetDNS, CheckPing, and TraceRoute functions. These are typically under Network Tools, Diagnostics, or System Utilities menus
    Affected if These functions exist and are accessible in the interface
  4. Verify function accessibility
    Determine if these functions can be invoked via HTTP requests without authentication, or check if they are exposed to unauthenticated or untrusted network segments
    Affected if The functions are reachable without proper authentication or from untrusted networks
  5. Assess network exposure
    Review firewall rules, access control lists, and network segmentation to determine if the device management interface is directly accessible from the internet or untrusted VLANs
    Affected if Device is exposed to untrusted networks without firewall protection

Environment is affected if running a Circutor SGE-PLC1000 or SGE-PLC50 with firmware >=9.0.2 and the GetDNS/CheckPing/TraceRoute functions are network-accessible

Mitigation

Apply vendor firmware patch when available; if no patch exists, isolate affected devices on a dedicated network segment and restrict access to these functions via firewall rules or access controls.
