Summary
SSA-476715: Two Vulnerabilities in Automation License Manager

Notes

Summary
Siemens Automation License Manager contains two vulnerabilities which, when combined, could allow an attacker to modify and rename license files, extract licenses and overwrite arbitrary files on the target system potentially leading to privilege escalation and remote code execution. The affected functionality is not available for remote attackers in the default configuration since version V6.0 SP2 of Automation License Manager. Siemens has released an update for Automation License Manager V6 and recommends to update to the latest version. Siemens 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
