Summary

CVE-2023-28865 is a medium-severity Insufficient Verification of Data Authenticity (CWE-345) vulnerability in Dieboldnixdorf Vynamic Security Suite. Its CVSS base score is 6.6 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique DCSync (T1003.006); ranked at the 17th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-23 (Session Authenticity) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SC-23 Session Authenticity good match

Explicit requirement to protect session authenticity structurally prevents the weakness for communications.

SC-8 Transmission Confidentiality and Integrity good match

SC-8 directly requires mechanisms to protect integrity of transmitted data, which structurally eliminates the missing checksum weakness in protocols.

SI-7 Software, Firmware, and Information Integrity good match

Integrity verification tools detect (but do not stop) the acceptance of data lacking authenticity.

SC-13 Cryptographic Protection partial match

Cryptographic mechanisms can be used to verify authenticity, thereby preventing acceptance of invalid data.

SC-16 Transmission of Security and Privacy Attributes partial match

Associating security attributes with exchanged information supports verification of authenticity.
