Affected Products and Solution.
Please follow the General Security 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.
The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS environmental score is specific to the customer’s environment and will impact the overall CVSS score. The environmental score should therefore be individually defined by the customer to accomplish final scoring.
An additional classification has been performed using the CWE classification, a community-developed list of common software security weaknesses. This serves as a common language and as a baseline for weakness identification, mitigation, and prevention efforts. A detailed list of CWE classes can be found at: https://cwe.mitre.org/.
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).

CWE | CWE-126: Buffer Over-read |
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).

CWE | CWE-126: Buffer Over-read |
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)
