CVE-2025-10992 is a medium-severity vulnerability identified in the roncoo-pay product developed by roncoo. The flaw resides in an unspecified function within the /user/info/lookupList endpoint, which suffers from improper authorization controls. This means that an attacker can remotely exploit this vulnerability without requiring any authentication or user interaction, potentially gaining unauthorized access to user information or functionality that should be restricted. The vulnerability is present up to the commit hash 9428382af21cd5568319eae7429b7e1d0332ff40, but due to the product's rolling release system, specific version numbers are not disclosed, complicating precise patch management. The vendor has been contacted but has not responded, and while the exploit has been publicly disclosed, there are no known active exploits in the wild at this time. The CVSS v4.0 base score is 6.9, reflecting a medium severity level, with the vector indicating network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality. The vulnerability's primary risk lies in unauthorized access due to insufficient authorization checks, which could lead to data exposure or unauthorized operations within the application context.

For European organizations using roncoo-pay, this vulnerability could lead to unauthorized access to sensitive user information or transactional data, undermining confidentiality and potentially enabling fraud or data leakage. Given the remote exploitability without authentication, attackers could leverage this flaw to target financial or payment processing systems, causing reputational damage, regulatory non-compliance (especially under GDPR), and financial losses. The improper authorization could also be exploited to manipulate user data or payment records, affecting data integrity. Although availability impact is not indicated, the breach of authorization controls alone poses significant risks in the financial services sector prevalent in Europe. Organizations relying on roncoo-pay for payment processing or user management should consider this vulnerability a serious concern, especially in sectors with stringent data protection requirements.

Since the vendor has not provided a patch or version-specific updates, European organizations should implement compensating controls immediately. These include: 1) Restricting network access to the /user/info/lookupList endpoint using firewalls or API gateways to limit exposure only to trusted internal networks or authenticated users; 2) Implementing additional authorization checks at the application or proxy level to enforce proper access controls; 3) Monitoring and logging all access attempts to this endpoint for unusual or unauthorized activity; 4) Conducting thorough code reviews and penetration testing focused on authorization logic within roncoo-pay; 5) If feasible, isolating the roncoo-pay service in segmented network zones to reduce attack surface; 6) Preparing incident response plans for potential exploitation scenarios; and 7) Engaging with the vendor or community for updates or patches and applying them promptly once available. Organizations should also consider alternative payment solutions if timely remediation is not possible.
