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
An Improper Privilege Management issue was discovered in SpiderControl SCADA Web Server Version 2.02.0007 and prior. Authenticated, non-administrative local users are able to alter service executables with escalated privileges, which could allow an attacker to execute arbitrary code under the context of the current system services.

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

SpiderControl SCADA Web Server versions 2.02.0007 and prior contain an improper privilege management vulnerability where authenticated non-administrative local users can modify service executables, enabling arbitrary code execution with elevated system service privileges.

MitigationRestrict write permissions on SCADA service executables to administrator accounts only, and apply vendor patch when available. Verify service account has minimal necessary privileges.

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 if SpiderControl SCADA Web Server is installed
    Open Windows Services (services.msc) and look for a service named 'SpiderControl' or 'ScadaWebServer' or check Program Files for a SpiderControl directory. Alternatively, run 'wmic product get name,version' to list installed software.
    Affected if No SpiderControl SCADA Web Server service or software is found on the system.
  2. Determine the installed version
    If found, check the version of the SpiderControl SCADA Web Server installation. Right-click the service > Properties to see the path to the executable, then right-click the executable > Properties > Details to view the version. Or check the registry under HKLM\SOFTWARE\SpiderControl or the uninstall entry in the registry.
    Affected if The installed version is 2.02.0007 or any version prior to this.
  3. Verify non-administrative user write access to service executables
    Locate the SCADA Web Server service executable (from the service Properties path). Right-click the executable file > Properties > Security tab > Permissions. Check if Users or Authenticated Users group has Write or Modify permissions to the executable file.
    Affected if Non-administrative users (Users group, Authenticated Users, or specific non-admin users) have Write or Modify permissions on the service executable.
  4. Check the service account configuration
    Open Services, find the SpiderControl service, right-click > Properties > Log On tab. Verify which account the service runs under (Local System, Local Service, or a specific user account).
    Affected if The service runs under Local System, Local Service, or another privileged account, and non-admin users have write access to the executable.
  5. Confirm local user authentication is enabled
    Check the SpiderControl web server configuration files (typically in the installation directory, look for config.xml, users.xml, or similar) to determine if local user accounts are enabled for authentication.
    Affected if Local user authentication is enabled and non-admin local users exist on the system.

A user is affected if SpiderControl SCADA Web Server version 2.02.0007 or prior is installed, the service runs with elevated privileges, and non-administrative local users have write permissions to the service executable with local authentication enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 2.02.0007
Interim mitigation

Restrict write permissions on SCADA service executables to administrator accounts only, and apply vendor patch when available. Verify service account has minimal necessary privileges.
