CVE-2025-10266 is a critical SQL Injection vulnerability affecting the NUP Portal product developed by NewType Infortech. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing unauthenticated remote attackers to inject arbitrary SQL code. This flaw enables attackers to read, modify, and delete database contents without any authentication or user interaction. The vulnerability is remotely exploitable over the network with low attack complexity and no privileges required, making it highly accessible to attackers. The CVSS 4.0 base score of 9.3 reflects the critical nature of this vulnerability, with high impact on confidentiality, integrity, and availability of the affected systems. Since the NUP Portal is likely a web-based application, the injection point could be any user input field that interacts with the backend database without proper sanitization or parameterization. Exploitation could lead to data breaches, data loss, unauthorized data manipulation, and potentially full compromise of the underlying database and application. Although no public exploits are currently known in the wild, the severity and ease of exploitation make it a prime target for attackers once exploit code becomes available. The lack of available patches at the time of publication increases the urgency for organizations to implement mitigations and monitor for suspicious activity. Given the criticality and unauthenticated access, this vulnerability represents a significant threat to any organization using the affected NUP Portal version.

For European organizations using the NUP Portal, this vulnerability poses a severe risk to sensitive data confidentiality and integrity. Attackers could exfiltrate personal data, financial records, or intellectual property stored in the backend databases, leading to regulatory non-compliance under GDPR and potential heavy fines. The ability to modify or delete data could disrupt business operations, cause data loss, and damage organizational reputation. Since the vulnerability requires no authentication, it increases the attack surface significantly, allowing external threat actors to target exposed portals directly. Critical sectors such as finance, healthcare, government, and manufacturing that rely on the NUP Portal for internal or customer-facing services are particularly at risk. The potential for widespread data compromise and service disruption could also impact supply chains and partner ecosystems across Europe. Furthermore, the absence of known exploits currently does not diminish the urgency, as attackers often develop exploits rapidly for high-severity vulnerabilities. European organizations must prioritize detection and mitigation to prevent exploitation and limit potential damage.

1. Immediate implementation of Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the NUP Portal. 2. Conduct thorough input validation and sanitization on all user inputs interacting with the database, employing parameterized queries or prepared statements to prevent injection. 3. Restrict database user permissions to the minimum necessary, avoiding use of highly privileged accounts for application database connections. 4. Monitor application logs and network traffic for unusual SQL queries or patterns indicative of injection attempts. 5. Isolate the NUP Portal environment from critical internal networks to limit lateral movement in case of compromise. 6. Engage with NewType Infortech for timely patches or updates; if unavailable, consider temporary mitigations such as disabling vulnerable features or restricting access to the portal via VPN or IP whitelisting. 7. Conduct security assessments and penetration testing focused on injection vulnerabilities to identify and remediate similar issues proactively. 8. Educate development and operations teams on secure coding practices and the importance of input validation to prevent future vulnerabilities.
