CISA's summary
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.

Vulnerabilities in this advisory
- CVE-2021-20093 — CVE-2021-20093 · CWE-126
A buffer over-read vulnerability in the CodeMeter Runtime network server could cause the server to return packets containing data from the heap. An unauthenticated remote attacker could exploit this issue to disclose heap memory contents or crash the CodeMeter Runtime Server (i.e., CodeMeter.exe).
- CVE-2021-20094 — CVE-2021-20094 · CWE-126
A buffer over-read vulnerability in the HTTP(S) service of the CodeMeter Runtime CmWAN server could cause the server to crash. An unauthenticated remote attacker with access to the CmWAN port could exploit this issue to crash the CodeMeter Runtime Server (i.e., CodeMeter.exe).
- CVE-2023-3935 — CVE-2023-3935 · CWE-122
In CodeMeter Runtime versions up to 7.60b, there is a heap buffer overflow vulnerability which can potentially lead to a remote code execution. Currently, no PoC is known to us. To exploit 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)
