CVSS v3.1

Official Description

The currency dispenser of NCR SelfSev ATMs running APTRA XFS 05.01.00 or earlier does not adequately authenticate session key generation requests from the host computer, allowing an attacker with physical access to internal ATM components to issue valid commands to dispense currency by generating a new session key that the attacker knows.

Technical Analysis

CVE-2020-10123 requires local access, meaning attackers must already have a foothold on the target system.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in full integrity compromise (data manipulation), with a CVSS base score of 5.3.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
