CVE-2020-10124 — Ncr Aptra Xfs security vulnerability

High CVSS 7.1

NCR SelfServ ATMs running APTRA XFS 05.01.00 do not encrypt, authenticate, or verify the integrity of messages between the BNA and the host computer, which could allow an attacker with physical access to the internal components of the ATM to execute arbitrary code, including code that enables the attacker to commit deposit forgery.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
