Listen to this Post
CVE-2025-7016 is an improper access control vulnerability (CWE-284) found in Akın Software’s QR Menu product, a digital menu solution used primarily in the hospitality sector . The flaw exists in versions prior to s1.05.12 and allows for authentication abuse . An attacker with low-level privileges can exploit this weakness over the network due to low attack complexity, although user interaction is required . By bypassing access restrictions, the attacker can escalate their privileges and perform actions reserved for higher-level users, leading to a full compromise of system confidentiality, integrity, and availability . The vulnerability was discovered by Şahnur Eren ALOĞLU and published by the Computer Emergency Response Team of the Republic of Turkey (TR-CERT) on January 29, 2026 . The official advisory is documented under TR-26-0006 by USOM .
Platform: Akın Software QR
Version: before s1.05.12
Vulnerability: Authentication Abuse
Severity: HIGH
date: 29/01/2026
Prediction: Patch likely soon
What Undercode Say:
Analytics
The vulnerability is remotely exploitable (AV:N) with low complexity (AC:L). It requires low privileges (PR:L) and user interaction (UI:R). The scope is unchanged (S:U), but the impact is high on confidentiality, integrity, and availability (C:H/I:H/A:H), resulting in a CVSS score of 8.0 . The EPSS score is currently very low at 0.00046, indicating a low probability of exploitation in the wild at the time of analysis .
Bash Commands (Conceptual Testing)
Check current version of QR Menu (example path)
cat /var/www/qrmenu/config/version.php | grep "s1.05.12"
Attempt to access admin panel with low-privilege cookie (conceptual)
curl -k -X GET https://target.com/qrmenu/admin/dashboard.php \
-H "Cookie: session=low_privilege_session_cookie" \
-v
Attempt privilege escalation via forced browsing (conceptual)
curl -k -X POST https://target.com/qrmenu/api/update_settings.php \
-H "Cookie: session=low_privilege_session_cookie" \
-d "setting=value" \
-w "%{http_code}\n"
Grep logs for authentication anomalies
sudo grep "Authentication" /var/log/qrmenu/access.log | grep -i "fail"
How Exploit
The exploitation relies on manipulating authentication tokens or directly accessing restricted endpoints. A low-privileged user (e.g., a staff account) can intercept their session cookie and attempt to access administrative functions (e.g., /admin, /api/user-management). Due to improper access controls, the server fails to validate the user’s permissions correctly, allowing the request to go through. This effectively bypasses the intended authentication checks, granting the attacker the ability to read sensitive customer data, modify menu pricing, or disrupt service availability .
Protection from this CVE
- Patch Immediately: Upgrade QR Menu to version s1.05.12 or later as soon as the vendor releases it .
- Network Segmentation: Isolate QR Menu servers from critical internal networks .
- Access Control Review: Audit all user roles and permissions to ensure strict separation of privileges.
- Multi-Factor Authentication (MFA): Enforce MFA for all administrative accounts .
- Monitoring: Deploy Web Application Firewalls (WAF) and monitor authentication logs for unusual access patterns .
Impact
Successful exploitation allows an attacker to achieve full system compromise. This includes unauthorized access to sensitive customer data (leading to GDPR/privacy breaches), the ability to manipulate or delete menu information and pricing (causing financial and reputational damage), and potential service disruption (impacting business operations in the hospitality sector) .
