Overview
A new vulnerability has been uncovered in the nbcio-boot platform, specifically in version 1.0.3. This vulnerability, designated as CVE-2025-50240, exposes systems to potential SQL Injection attacks via the userIds parameter at the /sys/user/deleteRecycleBin endpoint. SQL Injection is a code injection technique used to attack data-driven applications and can potentially lead to significant data breaches or complete system compromise.
This vulnerability is especially critical because it affects a prevalent software platform and exhibits a high severity score. It is crucial for system administrators, cybersecurity professionals, and all users of nbcio-boot v1.0.3 to understand this vulnerability, its potential impact, and the necessary steps to mitigate it.

How the Exploit Works
The vulnerability allows malicious actors to inject SQL queries into the userIds parameter at the /sys/user/deleteRecycleBin endpoint. The application does not properly sanitize the input, thus allowing an attacker to manipulate SQL queries and access, modify, or delete database contents. A successful exploit can lead to unauthorized access to sensitive data, data corruption, or even total system compromise.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited, using a malicious SQL statement in an HTTP request:
POST /sys/user/deleteRecycleBin HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "userIds": "1 OR 1=1; DROP TABLE users;" }In this example, the malicious SQL statement `1 OR 1=1; DROP TABLE users;` will result in deleting the users table from the database, if the SQL injection is successful.
Mitigation and Prevention
The best mitigation for this vulnerability is to apply the vendor’s patch as soon as it is available. Until then, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. Additionally, it is recommended to follow best security practices such as input validation, parameterized queries, or using ORM frameworks to prevent SQL injection vulnerabilities.
