NCR SelfServ ATMs running APTRA XFS 05.01.00 or earlier do not authenticate or protect the integrity of USB HID communications between the currency dispenser and the host computer, permitting an attacker with physical access to internal ATM components the ability to inject a malicious payload and execute arbitrary code with SYSTEM privileges on the host computer by causing a buffer overflow on the host.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
