The vulnerability resides within the \u003ccode\u003eRequest\u003c/code\u003e function of the \u003ccode\u003esrc/servers/database/server.js\u003c/code\u003e file. This flaw allows a remote attacker to inject arbitrary SQL commands through manipulation of input parameters. Public exploit code is available, increasing the risk of exploitation. Due to the software\u0026rsquo;s rolling release model, identifying specific vulnerable versions is challenging. The vendor was notified but did not respond to the disclosure, potentially delaying remediation efforts and increasing the window of opportunity for malicious actors to exploit this vulnerability.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a publicly accessible instance of mcp-data-vis.\u003c/li\u003e\n\u003cli\u003eThe attacker analyzes the \u003ccode\u003esrc/servers/database/server.js\u003c/code\u003e file to understand the structure of the \u003ccode\u003eRequest\u003c/code\u003e function.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious SQL injection payload targeting the \u003ccode\u003eRequest\u003c/code\u003e function.\u003c/li\u003e\n\u003cli\u003eThe attacker sends a specially crafted HTTP request containing the SQL injection payload to the vulnerable endpoint.\u003c/li\u003e\n\u003cli\u003eThe vulnerable \u003ccode\u003eRequest\u003c/code\u003e function processes the malicious SQL query without proper sanitization.\u003c/li\u003e\n\u003cli\u003eThe injected SQL code is executed against the backend database, potentially allowing data extraction.\u003c/li\u003e\n\u003cli\u003eThe attacker retrieves sensitive data from the database, such as user credentials or application configuration.\u003c/li\u003e\n\u003cli\u003eThe attacker could potentially use the compromised database to pivot to other systems within the network, or deface the web application.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive data, including user credentials and application configurations. The lack of versioning information due to the rolling release model makes it difficult to identify and patch vulnerable instances. Organizations using mcp-data-vis are at risk of data breaches, service disruption, and potential compromise of their entire infrastructure if this vulnerability is exploited.
