CVE-2016-6486
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 · uneditedSiemens SINEMA Server uses weak permissions for the application folder, which allows local users to gain privileges via unspecified vectors.
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 confidenceSiemens SINEMA Server contains weak file system permissions on its application installation folder, allowing local unprivileged users to modify or replace executable files and achieve privilege escalation.

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.
-
Locate SINEMA Server installation directoryCheck common installation paths such as C:\Program Files\Siemens\SINEMA Server or C:\Siemens\SINEMA Server, or use Windows Registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ProductCode} to find the InstallLocationAffected if Installation directory is found and exists on the system
-
Identify executable files in the installation folderList all .exe and .dll files within the SINEMA Server installation directory using 'dir /s /b *.exe *.dll' command or file explorerAffected if Executable files exist in the installation folder
-
Check file permissions on the application folderRight-click the SINEMA Server installation folder, select Properties, go to Security tab, and examine the permissions for Users or Authenticated Users groups. Alternatively, use 'icacls "<installation_path>"' commandAffected if Users or non-admin accounts have Write or Modify permissions to the folder
-
Verify executable file permissionsCheck permissions on .exe files within the installation folder using 'icacls "<path>\*.exe"' or by examining the Security tab properties of specific executable filesAffected if Non-privileged users have Write or Full Control permissions on executable files in the installation folder
-
Test write access with a limited user accountIf possible, attempt to modify or replace an executable file in the SINEMA Server installation folder using a non-administrator accountAffected if A non-privileged user can successfully modify or replace executable files in the installation folder
If non-privileged users have Write or Modify permissions on the SINEMA Server installation folder or its executable files, the system is affected by this vulnerability.

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 dataApply restrictive file system permissions to the SINEMA Server application folder, restricting write access to only the service account and administrators, then verify application functionality.
