Summary
SSA-640968: Untrusted Search Path Vulnerability in TIA Project-Server formerly known as TIA Multiuser Server

Notes

Summary
TIA Project-Server formerly known as TIA Multiuser Server contains an untrusted search path vulnerability that could allow an attacker to escalate privileges, when tricking a legitimate user to start the service from an attacker controlled path. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens is preparing further updates and recommends specific countermeasures for products where updates 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
