CVE-2025-50240 is a critical SQL injection vulnerability identified in nbcio-boot version 1.0.3. The vulnerability exists in the /sys/user/deleteRecycleBin endpoint, specifically via the userIds parameter. SQL injection (CWE-89) vulnerabilities occur when untrusted input is improperly sanitized and directly included in SQL queries, allowing an attacker to manipulate the database query logic. In this case, an attacker can craft malicious input for the userIds parameter to execute arbitrary SQL commands on the backend database. The CVSS 3.1 base score of 9.8 reflects the severity: the attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the system. Exploiting this vulnerability could allow an attacker to extract sensitive user data, modify or delete data, or disrupt service availability by corrupting or deleting database records. The vulnerability is publicly disclosed as of July 17, 2025, but no patches or known exploits in the wild have been reported yet. Given the criticality and the nature of the vulnerability, it poses a significant risk to any organization using nbcio-boot 1.0.3 or earlier versions if they expose this endpoint to untrusted networks. Attackers can remotely exploit this without authentication, making it highly dangerous in internet-facing deployments.

For European organizations, the impact of CVE-2025-50240 could be severe. Organizations relying on nbcio-boot 1.0.3 for user management or related backend services may face data breaches exposing personal or sensitive user information, violating GDPR and other data protection regulations. The ability to alter or delete data threatens operational integrity and could disrupt business continuity. This could lead to financial losses, reputational damage, and regulatory penalties. Critical sectors such as finance, healthcare, government, and telecommunications, which often handle sensitive personal and operational data, would be particularly vulnerable. Additionally, the lack of required privileges or user interaction means attackers can automate exploitation at scale, increasing the risk of widespread compromise across European enterprises. The vulnerability could also be leveraged as a foothold for further lateral movement or ransomware deployment within affected networks.

1. Immediate mitigation should include restricting access to the /sys/user/deleteRecycleBin endpoint to trusted internal networks only, using network segmentation and firewall rules. 2. Implement Web Application Firewalls (WAFs) with rules to detect and block SQL injection patterns targeting the userIds parameter. 3. Conduct thorough input validation and sanitization on all user-supplied parameters, especially userIds, employing parameterized queries or prepared statements to prevent injection. 4. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5. Engage with the vendor or development team to obtain or request a security patch or upgrade to a fixed version as soon as it becomes available. 6. Perform a comprehensive security audit of all nbcio-boot deployments to identify exposure and remediate accordingly. 7. Educate development and operations teams on secure coding practices to prevent similar vulnerabilities in future releases.
