The vulnerability identified as CVE-2025-50240 affects the nbcio-boot framework version 1.0.3 and represents a critical SQL injection flaw that could enable unauthorized access to sensitive data. This vulnerability specifically manifests through the userIds parameter within the /sys/user/deleteRecycleBin endpoint, which processes user deletion requests from the recycle bin. The flaw arises from inadequate input validation and sanitization practices that fail to properly escape or parameterize user-supplied data before incorporating it into database queries. The affected system processes the userIds parameter directly without proper security measures, creating an opportunity for malicious actors to inject arbitrary SQL commands that can manipulate the underlying database.
This SQL injection vulnerability falls under the Common Weakness Enumeration category CWE-89, which specifically addresses improper neutralization of special elements used in SQL commands. The attack surface is particularly concerning as it targets a user management endpoint that likely contains sensitive personal and operational data. The vulnerability enables an attacker to execute unauthorized database operations including data retrieval, modification, or deletion, potentially compromising user accounts and system integrity. The impact extends beyond simple data theft as the attacker could manipulate the database structure, escalate privileges, or even gain deeper system access through chained attacks that exploit the compromised user management functionality.
The operational impact of this vulnerability is severe and multifaceted, particularly within enterprise environments that rely on the nbcio-boot framework for their backend operations. An attacker exploiting this vulnerability could potentially access all user records, modify user permissions, delete critical system data, or even establish persistent access through database-level backdoors. The vulnerability affects the confidentiality, integrity, and availability of the system by allowing unauthorized data manipulation and access. Organizations using this framework may face regulatory compliance violations, data breach notifications, and significant reputational damage. The attack vector is relatively straightforward as it requires only a single parameter to be manipulated in the deleteRecycleBin endpoint, making it accessible to attackers with basic knowledge of SQL injection techniques and potentially automated exploitation tools.
Mitigation strategies for this vulnerability should be implemented immediately through multiple defensive layers. The primary remediation involves implementing proper input validation and parameterized queries throughout the application code, specifically addressing the userIds parameter handling in the deleteRecycleBin endpoint. Organizations should deploy web application firewalls that can detect and block SQL injection attempts targeting known vulnerable parameters. Input sanitization measures including character set filtering, length restrictions, and regular expression validation should be enforced to prevent malicious payloads from reaching the database layer. Additionally, implementing the principle of least privilege for database connections and enabling comprehensive logging of all database operations will aid in detecting exploitation attempts. The remediation process should include thorough code reviews and security testing to ensure all similar vulnerabilities are identified and addressed throughout the framework. Regular security updates and vulnerability assessments should be conducted to maintain protection against evolving attack techniques that may target similar weaknesses in the application architecture.
