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
CEServer.exe in the CEServer component in the Remote Agent module in InduSoft Web Studio 6.1 and 7.0 does not require authentication, which allows remote attackers to execute arbitrary code via vectors related to creation of a file, loading a DLL, and process control.

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

CEServer.exe in the CEServer component of InduSoft Web Studio Remote Agent module (versions 6.1 and 7.0) lacks authentication requirements, allowing unauthenticated remote attackers to execute arbitrary code via file creation, DLL loading, and process control operations.

MitigationRestrict network access to the CEServer component using firewalls or network segmentation, and avoid exposing the Remote Agent module to untrusted networks. Apply vendor patches if available.

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. Check installed InduSoft Web Studio version
    Look in Windows Programs and Features, or check the installation directory for version information in the application files or registry under HKLM\SOFTWARE\InduSoft
    Affected if The installed version is 6.1 or 7.0 exactly
  2. Locate CEServer.exe component
    Search for CEServer.exe in the InduSoft Web Studio installation folder (commonly under C:\Program Files\InduSoft or C:\Program Files (x86)\InduSoft)
    Affected if CEServer.exe exists in the installation directory
  3. Verify Remote Agent module is enabled
    Check the InduSoft project or configuration settings for Remote Agent module activation, or look for running CEServer.exe processes
    Affected if The Remote Agent module is enabled or CEServer.exe is running as a service
  4. Check network exposure of CEServer
    Use netstat -ano or a port scanner to see if CEServer.exe is listening on TCP ports (commonly ports 3000-3002 or as configured for Remote Agent)
    Affected if CEServer is listening on accessible network ports and reachable from untrusted networks

A user is affected if they have InduSoft Web Studio version 6.1 or 7.0 installed with the CEServer Remote Agent module enabled and exposed to the network.
