Integer overflow in Siemens products - CVE-2023-28831

Vulnerability identifier: #VU80852

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2023-28831

CWE-ID: CWE-190

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer overflow in the ANSI C OPC UA SDK. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
