CVE-2025-50240 is a 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 vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing an attacker to manipulate the database query. In this case, an attacker could craft malicious input for the userIds parameter to execute arbitrary SQL commands against the backend database. This could lead to unauthorized data access, data modification, or deletion, and potentially allow privilege escalation or further compromise of the application and underlying systems. The vulnerability does not have a CVSS score assigned yet, and no known exploits in the wild have been reported as of the published date. The lack of patch links suggests that a fix may not yet be publicly available. The vulnerability affects nbcio-boot v1.0.3, but no other version information is provided. The endpoint involved, /sys/user/deleteRecycleBin, implies that the function is related to user account management, specifically the deletion of recycled or soft-deleted user records, which could be a sensitive operation with elevated privileges. Exploitation would likely not require authentication if the endpoint is exposed without proper access controls, but this is not explicitly stated. Given the nature of SQL injection, the attack could be automated and remotely executed, increasing the risk of exploitation if the system is internet-facing or accessible by untrusted users.

For European organizations using nbcio-boot v1.0.3, this vulnerability could have significant impacts. If exploited, attackers could gain unauthorized access to sensitive user data, including personally identifiable information (PII), which is highly regulated under GDPR. Data integrity could be compromised by unauthorized modification or deletion of user records, potentially disrupting business operations and user management processes. Availability could also be affected if attackers execute destructive SQL commands, leading to denial of service or data loss. The reputational damage and regulatory penalties resulting from a data breach or failure to protect user data could be severe. Additionally, if the application is integrated into critical business workflows or infrastructure, the impact could extend to broader operational disruptions. The absence of known exploits in the wild provides a window of opportunity for organizations to proactively address the vulnerability before active attacks occur.

Organizations should immediately review their use of nbcio-boot v1.0.3 and assess exposure of the /sys/user/deleteRecycleBin endpoint. Specific mitigation steps include: 1) Implement strict input validation and parameterized queries or prepared statements to prevent SQL injection on the userIds parameter. 2) Restrict access to the vulnerable endpoint using strong authentication and authorization controls, ensuring only trusted and authenticated users can invoke it. 3) Monitor logs for suspicious activity related to the deleteRecycleBin function, such as unusual or malformed userIds inputs. 4) If possible, isolate or firewall the application to limit access to trusted networks or users. 5) Engage with the vendor or development team to obtain or develop a patch or upgrade to a version that addresses the vulnerability. 6) Conduct a security review or penetration test focusing on SQL injection and related vulnerabilities in nbcio-boot. 7) Prepare incident response plans to quickly contain and remediate any exploitation attempts. These steps go beyond generic advice by focusing on the specific vulnerable endpoint and parameter, emphasizing access control and proactive monitoring.
