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
Cscape (All versions prior to 9.90 SP4) is configured by default to be installed for all users, which allows full permissions, including read/write access. This may allow unprivileged users to modify the binaries and configuration files and lead to local privilege escalation.

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

Cscape versions prior to 9.90 SP4 default to an all-users installation with overly permissive file system ACLs, granting read/write access to all users on the system. This allows unprivileged users to modify executable binaries and configuration files in the installation directory, which can be leveraged for local privilege escalation when the software runs with elevated privileges.

MitigationUpgrade to Cscape version 9.90 SP4 or later, which addresses the default permission misconfiguration; alternatively, manually restrict file system permissions on the installation directory to administrative-only access.

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. Locate Cscape installation directory
    Check common installation paths such as C:\Program Files\Hornerautomation\Cscape or C:\Program Files (x86)\Hornerautomation\Cscape, or search for the Cscape executable file on the system
    Affected if Cscape is found installed on the system
  2. Determine installed Cscape version
    Right-click on the Cscape executable (typically Cscape.exe) in the installation folder, select Properties, and check the Details tab for the Product Version, or check the version in the application via Help > About
    Affected if The version displayed is prior to 9.90 or equals 9.90 (versions 9.90 SP4 and later are not affected)
  3. Inspect ACLs on the Cscape installation folder
    Right-click the Cscape installation folder, select Properties > Security tab, and examine the permissions for each user or group listed. Verify whether users other than Administrators and System have Write or Modify permissions
    Affected if Non-administrative users or the 'Users' group are granted Write or Modify access to the installation directory
  4. Check ACLs on executable files in the installation folder
    Right-click on Cscape.exe and other executable files in the installation folder, select Properties > Security, and verify if standard users have Write permission
    Affected if Standard users have Write permission to executable files in the installation directory
  5. Verify if Cscape runs with elevated privileges
    Check if there are scheduled tasks, services, or shortcuts configured to run Cscape with 'Run as administrator' or elevated privileges, or examine shortcut properties for such settings
    Affected if Cscape is configured to execute with elevated or administrative privileges while the installation directory remains writable by non-privileged users

The environment is affected if Cscape version 9.90 or prior is installed with default permissions that allow non-administrative users to write to the installation directory, especially if the software runs with elevated privileges.
