CVE-2025-64276 is a missing authorization vulnerability identified in Ays Pro Survey Maker, a software product used for creating and managing surveys. The flaw exists in versions up to and including 5.1.9.4 and stems from incorrectly configured access control security levels. Specifically, the vulnerability allows an attacker with some level of privileges (PR:L - low privileges) to bypass authorization checks and access or manipulate survey data or functionalities that should be restricted. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N), which increases its risk profile. The CVSS 3.1 base score is 6.5, indicating a medium severity level primarily due to the high impact on confidentiality (C:H) but no impact on integrity (I:N) or availability (A:N). This means sensitive survey data could be exposed to unauthorized users, potentially leading to privacy violations or data leakage. No known exploits have been reported in the wild yet, but the vulnerability's nature suggests it could be leveraged for unauthorized data access or information gathering. The lack of patches at the time of publication necessitates immediate attention to access control configurations and monitoring for suspicious activities. Given the product's role in collecting and storing survey responses, which may include personal or sensitive information, this vulnerability poses a significant risk to data confidentiality.

For European organizations, the primary impact of CVE-2025-64276 is unauthorized access to sensitive survey data, which can include personal data protected under GDPR. Exposure of such data could lead to regulatory penalties, reputational damage, and loss of customer trust. Organizations relying on Ays Pro Survey Maker for market research, customer feedback, or internal surveys may inadvertently expose confidential information to unauthorized parties. Since the vulnerability does not affect data integrity or availability, operational disruptions are less likely; however, the confidentiality breach alone is critical given Europe's stringent data protection laws. Additionally, attackers exploiting this vulnerability could gain insights into internal processes or customer sentiments, which could be leveraged for further targeted attacks or social engineering campaigns. The medium severity rating suggests that while the vulnerability is serious, it requires some level of privilege to exploit, somewhat limiting the attack surface. Nonetheless, organizations with weak internal access controls or exposed survey management interfaces are at higher risk.

1. Immediately review and tighten access control policies within Ays Pro Survey Maker, ensuring that users have only the minimum necessary privileges. 2. Restrict network access to the survey management interface using firewalls or VPNs to limit exposure to trusted users only. 3. Monitor logs for unusual access patterns or privilege escalations related to survey management activities. 4. Implement multi-factor authentication (MFA) for all accounts with access to the survey maker administration. 5. Segregate survey data storage from other critical systems to minimize lateral movement in case of compromise. 6. Regularly audit user roles and permissions within the application to detect and remediate misconfigurations. 7. Stay informed about vendor updates and apply patches promptly once released to address this vulnerability. 8. Conduct penetration testing focused on authorization controls to identify similar weaknesses proactively. 9. Educate staff managing the survey software about the importance of access controls and signs of potential exploitation attempts.
