CVE-2023-28831
7.5 · HIGHOverview
CVE-2023-28831 is a high-severity vulnerability affecting siemens simatic_cloud_connect_7_cc712_firmware. It was published on September 12, 2023 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The OPC UA implementations (ANSI C and C++) in affected products contain an integer overflow vulnerability that could cause the application to run into an infinite loop during certificate validation.
This could allow an unauthenticated remote attacker to create a denial of service condition by sending a specially crafted certificate.
Remediation
Check the references section for vendor advisories and patches from siemens. Update simatic_cloud_connect_7_cc712_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
