Wibu-Systems CodeMeter Runtime
Notes
Summary
WIBU Systems published information about two vulnerabilities and an associated fix release version of CodeMeter Runtime, a product provided by WIBU Systems and used in several Siemens products for license management.
The vulnerabilities are described in the section "Vulnerability Classification" below and got assigned the CVE IDs CVE-2021-20093 and CVE-2021-20094. Successful exploitation of these vulnerabilities could allow an attacker to read data from the heap of the CodeMeter Runtime network server, or crash the CodeMeter Runtime Server (i.e., CodeMeter.exe).
Siemens has released updates for several affected products and recommends to update to the latest versions. 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

Wibu-Systems CodeMeter Runtime
Notes
Summary
WIBU Systems published information about two vulnerabilities and an associated fix release version of CodeMeter Runtime, a product provided by WIBU Systems and used in several Siemens products for license management.
The vulnerabilities are described in the section "Vulnerability Classification" below and got assigned the CVE IDs CVE-2021-20093 and CVE-2021-20094. Successful exploitation of these vulnerabilities could allow an attacker to read data from the heap of the CodeMeter Runtime network server, or crash the CodeMeter Runtime Server (i.e., CodeMeter.exe).
Siemens has released updates for several affected products and recommends to update to the latest versions. 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.

Summary
Siemens Desigo CC product family
Notes
Summary
Versions V5.0 through V7 of the Desigo CC product family (Desigo CC, Desigo CC Compact, Desigo CC Connect, Cerberus DMS), as well as the Desigo CC-based SENTRON powermanager, are affected by multiple vulnerabilities in the underlying third-party component WIBU Systems CodeMeter Runtime.
Successful exploitation of these vulnerabilities could allow remote attackers to execute arbitrary code on the Desigo CC server, or create a denial of service condition.
While all Desigo CC version lines V5.0, V5.1 and V6 are affected by all listed vulnerabilities, V7 is only affected by CVE-2023-3935.
Siemens has released a patch to update the CodeMeter Runtime component and recommends to apply the patch on affected systems.
General Recommendations
As a general security measure Siemens strongly recommends to protect network access to affected products with appropriate mechanisms. It is advised to follow recommended security practices in order to run the devices in a protected IT environment.

Summary
Siemens Desigo CC product family
Notes
Summary
Versions V5.0 through V7 of the Desigo CC product family (Desigo CC, Desigo CC Compact, Desigo CC Connect, Cerberus DMS), as well as the Desigo CC-based SENTRON powermanager, are affected by multiple vulnerabilities in the underlying third-party component WIBU Systems CodeMeter Runtime.
Successful exploitation of these vulnerabilities could allow remote attackers to execute arbitrary code on the Desigo CC server, or create a denial of service condition.
While all Desigo CC version lines V5.0, V5.1 and V6 are affected by all listed vulnerabilities, V7 is only affected by CVE-2023-3935.
Siemens has released a patch to update the CodeMeter Runtime component and recommends to apply the patch on affected systems.
General Recommendations
As a general security measure Siemens strongly recommends to protect network access to affected products with appropriate mechanisms. It is advised to follow recommended security practices in order to run the devices in a protected IT environment.

To\r\nexploit the heap overflow, additional protection mechanisms need to be broken. Remote access is only possible if CodeMeter is configured as a server. If CodeMeter is not configured as a server, the adversary would need to log in to the machine where the CodeMeter Runtime is running or trick the user into sending a malicious request to CodeMeter. This might result in an escalation of privilege. (WIBU-230704-01)",

Summary
SSA-625850: Multiple WIBU Systems CodeMeter Vulnerabilities Affecting the Desigo CC Product Family and SENTRON powermanager
Notes
Summary
Versions V5.0 through V7 of the Desigo CC product family (Desigo CC, Desigo CC Compact, Desigo CC Connect, Cerberus DMS), as well as the Desigo CC-based SENTRON powermanager, are affected by multiple vulnerabilities in the underlying third-party component WIBU Systems CodeMeter Runtime.
Successful exploitation of these vulnerabilities could allow remote attackers to execute arbitrary code on the Desigo CC server, or create a denial of service condition.
While all Desigo CC version lines V5.0, V5.1 and V6 are affected by all listed vulnerabilities, V7 is only affected by CVE-2023-3935.
Siemens has released a patch to update the CodeMeter Runtime component and recommends to apply the patch on affected systems.
General Recommendations
As a general security measure Siemens strongly recommends to protect network access to affected products with appropriate mechanisms. It is advised to follow recommended security practices in order to run the devices in a protected IT environment.
