CVE-2020-7527
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 · uneditedIncorrect Default Permission vulnerability exists in SoMove (V2.8.1) and prior which could cause elevation of privilege and provide full access control to local system users to SoMove component and services when a SoMove installer script is launched.
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 · moderate confidenceSoMove V2.8.1 and prior versions contain incorrect default file and service permissions that allow local unprivileged users to gain elevated access to SoMove components and services. The vulnerability is introduced during the installer script execution, where insufficient permission controls grant broader access than intended.

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 checksWork through these to decide whether this CVE applies to you.
-
Check if SoMove is installedLook for SoMove installation directory. Common paths: C:\Program Files\Schneider Electric\SoMove or C:\Program Files (x86)\Schneider Electric\SoMove on Windows. On Linux, check /opt/SoMove or /usr/local/SoMove. Use: dir /s /b SoMove.exe (Windows) or find / -name 'SoMove*' 2>/dev/null (Linux).Affected if SoMove software is found installed on the system
-
Identify installed SoMove versionLocate SoMove executable (SoMove.exe on Windows, somove on Linux) and check its version property. In Windows, right-click the file > Properties > Details tab. Or run: powershell (Get-Item 'C:\Program Files\Schneider Electric\SoMove\SoMove.exe').VersionInfoAffected if Version is 2.8.1 or any version lower (e.g., 2.8.0, 2.7.x, etc.)
-
Examine file permissions on SoMove installation folderRight-click the SoMove installation folder > Properties > Security tab. Check the permissions for Users group and other non-admin users. Run: icacls 'C:\Program Files\Schneider Electric\SoMove' (Windows) or ls -la /path/to/SoMove (Linux).Affected if Users group or non-privileged accounts have Full Control, Modify, or Write permissions beyond what is required for normal operation
-
Check service configuration file permissionsLook for service-related config files in the SoMove directory (e.g., .xml, .ini, or service registration files). Run: icacls 'C:\Program Files\Schneider Electric\SoMove\*' | findstr /i 'Users Everyone' (Windows).Affected if Service configuration files are writable by non-privileged users or Users group
-
Verify service binary permissionsCheck if service executables (typically in a subfolder like bin, exe, or service) have weak permissions. Run: icacls 'C:\Program Files\Schneider Electric\SoMove\*' | findstr /i 'Everyone Users' (Windows).Affected if Service executables are modifiable by unprivileged users
SoMove version 2.8.1 or lower is installed AND the installation directory or service files have overly permissive access controls granting write/modify access to standard users, allowing potential privilege escalation.

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 dataReview and correct file system permissions on SoMove installation directories and service configurations to enforce least-privilege access controls. Update installer scripts to set appropriate restrictive permissions during installation.
