CVE-2025-7016 is an improper access control vulnerability classified under CWE-284 affecting the QR Menu software developed by Akın Software Computer Import Export Industry and Trade Ltd. This vulnerability exists in versions prior to s1.05.12 and allows an attacker to abuse authentication mechanisms, effectively bypassing intended access restrictions. The flaw permits an authenticated user with limited privileges (low privilege) to escalate their access rights or perform unauthorized actions that should be restricted. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H) indicates that the vulnerability is remotely exploitable over the network with low attack complexity, requires low privileges, and some user interaction, but results in high impact on confidentiality, integrity, and availability. The vulnerability could allow attackers to access sensitive data, modify or delete information, or disrupt service availability. Although no public exploits have been reported yet, the high severity and ease of exploitation make it a critical concern. The vulnerability is particularly relevant for environments where QR Menu software is deployed to facilitate customer interactions, such as restaurants and retail, where unauthorized access could lead to data leakage or service manipulation. The lack of available patches at the time of reporting emphasizes the need for immediate vendor engagement and deployment of compensating controls until updates are available.

For European organizations, especially those in hospitality, retail, and food services that utilize the QR Menu software, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to customer data, including potentially sensitive personal information, resulting in privacy breaches and regulatory non-compliance under GDPR. Integrity of menu data and pricing could be compromised, leading to financial losses or reputational damage. Availability impacts could disrupt customer service operations, causing business interruptions. Given the network-exposed nature of the software, attackers could remotely exploit this vulnerability, increasing the attack surface. The high impact on confidentiality, integrity, and availability combined with the ease of exploitation means that organizations could face data breaches, fraud, and operational downtime. This is particularly critical for large hospitality chains and service providers with multiple locations across Europe, where centralized management of QR Menu systems is common.

1. Immediately upgrade the QR Menu software to version s1.05.12 or later once available from Akın Software to address the improper access control issue. 2. Until patches are deployed, implement strict network segmentation to isolate QR Menu systems from critical internal networks. 3. Enforce strong authentication and authorization policies, including multi-factor authentication (MFA) for any administrative or privileged access to the QR Menu platform. 4. Monitor authentication logs and access patterns for anomalies that could indicate abuse or exploitation attempts. 5. Conduct regular security assessments and penetration testing focused on access control mechanisms within the QR Menu environment. 6. Educate staff on recognizing suspicious activities related to QR Menu usage and reporting potential security incidents promptly. 7. Collaborate with the vendor for timely updates and security advisories. 8. Consider deploying Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) to detect and block exploitation attempts targeting this vulnerability.
