Summary
SSA-240541: WIBU Systems CodeMeter Heap Buffer Overflow Vulnerability in Industrial Products

Notes

Summary
WIBU Systems published information about a heap buffer overflow vulnerability and associated fix releases of CodeMeter Runtime, a product provided by WIBU Systems and used in several Siemens industrial products for license management. The vulnerability is described in the section 'Vulnerability Classification' below and got assigned the CVE ID CVE-2023-3935. Successful exploitation of this vulnerability could allow - an unauthenticated remote attacker to execute code on vulnerable products, where CodeMeter Runtime (i.e., CodeMeter.exe) is configured as a server, or - an authenticated local attacker to gain root/admin privileges on vulnerable products, where CodeMeter Runtime is configured as a client. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures 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.
