CVE-2025-66117 identifies a missing authorization vulnerability in the Ays Pro Easy Form product, affecting versions up to 2.7.8. This vulnerability arises from incorrectly configured access control security levels, which allow unauthenticated remote attackers to bypass authorization checks. The flaw specifically impacts the integrity of the system by enabling unauthorized users to modify or manipulate data submitted or managed through the Easy Form application. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N) indicates that the attack can be carried out remotely over the network without any privileges or user interaction, and it affects only the integrity of the data, not confidentiality or availability. Although no public exploits have been reported, the vulnerability's nature suggests that attackers could leverage it to alter form data, potentially disrupting business processes, corrupting records, or injecting malicious content. The lack of patch links in the provided information suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation steps. The vulnerability is particularly concerning for organizations relying on Easy Form for critical data collection or workflow automation, as unauthorized changes could have cascading effects on operations and decision-making.

For European organizations, the primary impact of CVE-2025-66117 is the compromise of data integrity within applications using Ays Pro Easy Form. This could lead to unauthorized data manipulation, undermining trust in collected data and potentially causing operational disruptions. Industries such as finance, healthcare, government, and e-commerce that depend on accurate form data are especially vulnerable. The lack of confidentiality and availability impact reduces the risk of data leakage or service downtime but does not diminish the threat to business processes reliant on data accuracy. Additionally, regulatory compliance frameworks like GDPR emphasize data integrity, so exploitation could lead to compliance violations and associated penalties. The ease of exploitation without authentication or user interaction increases the likelihood of attacks, particularly targeting organizations with internet-facing Easy Form deployments. The absence of known exploits in the wild currently lowers immediate risk but does not preclude future exploitation attempts.

1. Monitor vendor communications closely for official patches or updates addressing CVE-2025-66117 and apply them promptly once available. 2. Conduct a thorough review of access control configurations within Easy Form installations to ensure that authorization checks are correctly enforced for all sensitive operations. 3. Implement network-level restrictions such as web application firewalls (WAFs) to detect and block suspicious requests targeting Easy Form endpoints. 4. Employ logging and monitoring solutions to identify unusual form submission patterns or unauthorized modification attempts. 5. Restrict public exposure of Easy Form interfaces where possible, limiting access to trusted networks or VPNs. 6. Educate administrators and developers on secure configuration best practices to prevent similar authorization issues. 7. Consider temporary compensating controls such as disabling vulnerable features or requiring authentication until patches are deployed. 8. Perform penetration testing focused on access control validation to proactively identify and remediate weaknesses.
