Summary
SSA-563922: Local Privilege Escalation Vulnerability in SIMOTION Tools
Notes
Summary: Several tools for the SIMOTION system are affected by a local privilege escalation vulnerability. This could allow an attacker to execute arbitrary code with SYSTEM privileges when a legitimate user installs an application that uses the affected setup component. This vulnerability poses a risk only during setup and installation phase of the affected tools. Siemens has released a new version for SIMATIC Technology Package TPCamGen and recommends to update to the latest version. Siemens recommends specific mitigations for products where fixes are not or not yet available.
General Recommendations: As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

CVE-2025-43715

Nullsoft Scriptable Install System (NSIS) before 3.11 on Windows allows local users to escalate privileges to SYSTEM during an installation, because the temporary plugins directory is created under %WINDIR%\temp and unprivileged users can place a crafted executable file by winning a race condition. This occurs because EW_CREATEDIR does not always set the CreateRestrictedDirectory error flag.
