CVE-2025-10266 is a critical SQL Injection vulnerability identified in the NUP Portal product developed by NewType Infortech. This vulnerability arises due to improper neutralization of special elements used in SQL commands (CWE-89), allowing unauthenticated remote attackers to inject arbitrary SQL code. Exploitation does not require any authentication or user interaction, and the attack vector is network-based, meaning the attacker can exploit it remotely over the internet or internal networks. Successful exploitation can lead to unauthorized reading, modification, or deletion of database contents, severely compromising the confidentiality, integrity, and availability of the affected system's data. The CVSS 4.0 base score of 9.3 reflects the high impact and ease of exploitation, with no privileges or user interaction required. The vulnerability affects version 0 of the NUP Portal, indicating either an initial or early release version. Although no public exploits are currently known in the wild, the critical nature and straightforward exploitation path make it a significant threat. The lack of available patches at the time of publication further increases the urgency for mitigation. Given the nature of SQL Injection, attackers could also leverage this vulnerability to escalate privileges, pivot within the network, or exfiltrate sensitive information, potentially impacting broader organizational security.

For European organizations using the NUP Portal, this vulnerability poses a severe risk. Compromise of the underlying database could lead to exposure of sensitive personal data, intellectual property, or operational information, which may violate GDPR and other data protection regulations, resulting in legal and financial penalties. The ability to modify or delete data can disrupt business operations, cause loss of trust, and damage reputation. Additionally, attackers could use the compromised system as a foothold for further attacks within the network, potentially affecting other critical infrastructure. The unauthenticated nature of the vulnerability means that any exposed instance of the NUP Portal is at immediate risk, increasing the likelihood of exploitation. Organizations in sectors such as government, finance, healthcare, and critical infrastructure, where data integrity and confidentiality are paramount, are particularly vulnerable. The absence of known exploits currently does not diminish the threat, as the vulnerability is straightforward to exploit and may attract attackers soon after disclosure.

Given the lack of official patches, European organizations should immediately implement compensating controls. These include deploying web application firewalls (WAFs) with specific rules to detect and block SQL Injection attempts targeting the NUP Portal. Network segmentation should be enforced to limit access to the NUP Portal to trusted internal users only, reducing exposure. Conduct thorough input validation and sanitization on all user inputs interacting with the portal, employing parameterized queries or prepared statements if source code access is available. Organizations should monitor logs for unusual database queries or access patterns indicative of exploitation attempts. Rapidly develop and deploy patches or updates from NewType Infortech once available. Additionally, conduct security assessments and penetration testing focused on the NUP Portal to identify and remediate any other vulnerabilities. Finally, ensure that backups of critical data are current and tested for restoration to mitigate potential data loss from malicious deletion.
