CVE-2025-61429 is a privilege escalation vulnerability identified in NCR Atleos Terminal Manager (ConfigApp) version 3.4.0. The vulnerability arises from improper handling of requests within the ConfigApp component, allowing an attacker to craft a malicious request that escalates their privileges beyond intended limits. This escalation could enable unauthorized users to execute administrative actions or access sensitive configuration settings on the terminal management system. Although the exact technical mechanism of the crafted request is not detailed, the impact involves compromising the integrity and confidentiality of the terminal management environment. The vulnerability is currently published without an assigned CVSS score and no known exploits have been reported in the wild, indicating it may be newly discovered or not yet weaponized. NCR Atleos Terminal Manager is commonly used in retail environments to manage payment terminals and related infrastructure, making this vulnerability particularly relevant to organizations in sectors reliant on NCR hardware and software. The lack of patch information suggests that remediation is pending, emphasizing the need for proactive risk management. Given the nature of privilege escalation, attackers could leverage this flaw to gain control over terminal configurations, potentially leading to fraudulent transactions or disruption of payment services.

For European organizations, the impact of CVE-2025-61429 could be significant, especially for those in retail, hospitality, and financial services sectors that utilize NCR Atleos Terminal Manager to oversee payment terminals. Successful exploitation could lead to unauthorized administrative access, enabling attackers to alter terminal configurations, intercept or manipulate payment data, or disrupt terminal operations. This could result in financial losses, reputational damage, and regulatory compliance issues under GDPR and payment card industry standards. The compromise of terminal management systems could also serve as a foothold for broader network intrusion. Given the critical role of payment terminals in commerce, any disruption or data breach could have cascading effects on business continuity and customer trust. The absence of known exploits provides a window for mitigation, but also underscores the urgency for organizations to assess exposure and implement controls proactively.

Organizations should immediately inventory their NCR Atleos Terminal Manager deployments to identify affected versions, particularly version 3.4.0. Until an official patch is released, restrict access to the ConfigApp interface to trusted administrators only, using network segmentation and firewall rules to limit exposure. Implement strict authentication and authorization controls around terminal management systems. Monitor logs and network traffic for unusual or unauthorized requests targeting the ConfigApp component. Engage with NCR support channels to obtain updates on patch availability and apply security updates promptly once released. Additionally, conduct security awareness training for administrators to recognize potential exploitation attempts. Consider deploying intrusion detection systems tailored to detect anomalous requests indicative of privilege escalation attempts. Finally, review and harden terminal management policies to minimize the attack surface.
