Vulnerability from fkie_nvd - Published: 2020-08-21 21:15 - Updated: 2025-11-04 20:15
Severity ?
7.6 (High) - CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Summary
NCR SelfServ ATMs running APTRA XFS 05.01.00 do not properly validate softare updates for the bunch note acceptor (BNA), enabling an attacker with physical access to internal ATM components to restart the host computer and execute arbitrary code with SYSTEM privileges because while booting, the update process looks for CAB archives on removable media and executes a specific file without first validating the signature of the CAB archive.
