A critical vulnerability exists in the Neuron PHP framework that allows an attacker to execute destructive database commands by manipulating the AI agent. Successful exploitation could lead to the complete loss or corruption of application data, causing significant business disruption. Organizations using affected versions of the Neuron framework are urged to apply the recommended security update immediately.

The vulnerability lies within the MySQLWriteTool component of the Neuron framework. This tool is designed to execute SQL queries against a MySQL database but lacks sufficient semantic restrictions on the types of queries it can run. An attacker can leverage prompt injection or indirect prompt manipulation techniques to trick a Large Language Model (LLM) integrated with the framework into generating malicious SQL statements. The MySQLWriteTool will then execute these arbitrary queries, which can include destructive commands like DROP TABLE, TRUNCATE, DELETE, or privilege modification statements, leading to unauthorized data destruction, modification, or a denial of service. The attack's success and impact are contingent on the database user permissions configured for the tool.

This vulnerability is rated as critical severity with a CVSS score of 9.4, reflecting the potential for severe and widespread damage. A successful exploit could result in the complete and irreversible destruction of business-critical data, leading to catastrophic operational downtime and significant financial loss. The manipulation or deletion of sensitive information could also trigger regulatory penalties and cause severe reputational harm. Organizations that expose an AI agent using the vulnerable tool to untrusted input and have configured it with a highly privileged database account face the highest risk of data loss and system compromise.

Immediate Action: Immediately upgrade all instances of the Neuron framework to version 2.8.12 or a later, patched version as recommended by the vendor. After patching, monitor database and application logs for any signs of attempted or successful exploitation that may have occurred prior to the update.

Proactive Monitoring:

• Monitor database query logs for an unusual volume of destructive SQL commands such as DROP, TRUNCATE, DELETE, ALTER, or GRANT originating from the application server.
• Review application logs for errors or unexpected behaviors related to database interactions initiated by the MySQLWriteTool.
• Implement alerts for any modifications to database schemas or user privileges that are not part of a planned change management process.

Compensating Controls: If immediate patching is not feasible, implement the following controls to mitigate risk:

• Principle of Least Privilege: Ensure the database user account configured for the MySQLWriteTool has the minimum permissions required for its intended function. Specifically, revoke permissions for DROP, TRUNCATE, ALTER, and other Data Definition Language (DDL) or Data Control Language (DCL) statements.
• Disable the Tool: If the MySQLWriteTool is not essential for business operations, disable it entirely within the application's configuration.
• Input Sanitization: Implement an intermediary validation layer that inspects the SQL generated by the LLM before it is passed to the MySQLWriteTool, blocking queries containing high-risk keywords.

Public Exploit Available: false

Given the critical CVSS score of 9.4 and the potential for complete data destruction, this vulnerability poses a severe risk to the organization. We strongly recommend that all affected systems be patched to version 2.8.12 or newer on an emergency basis. If patching must be delayed, the implementation of compensating controls, particularly enforcing the principle of least privilege on the associated database account, should be treated as the highest priority to limit potential damage. Although this vulnerability is not currently on the CISA KEV list, its severity warrants immediate attention and remediation.
