CVE-2023-28865 is a medium-severity vulnerability rated 6.6/10 on the CVSS scale. Diebold Nixdorf Vynamic Security Suite (VSS) before 3.3.0 SR15, 4.0.0 SR05, 4.1.0 SR03, and 4.2.0 SR02 fails to validate the directory contents of certain directories (e.g., ensuring the expected hash sum) during the Pre-Boot Authorization (PBA) process. This can be exploited by a physical attacker who is able to manipulate the contents of the system's hard disk.. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
