Overview<\/strong><\/p>\n

This report presents a comprehensive analysis of the vulnerability identified as CVE-2025-56404. This vulnerability resides in MariaDB MCP 0.1.0 and allows attackers to gain access to sensitive data potentially leading to system compromise or data leakage. As MariaDB is widely used, its security vulnerabilities matter to a broad spectrum of systems and applications. Mitigation strategies and patches are available to address this issue.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-56404
\nSeverity: High (7.5\/10)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

MariaDB MCP | 0.1.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from a lack of user validation in the Server-Sent Events (SSE) service within MariaDB MCP 0.1.0. An attacker can exploit this flaw by sending malicious requests to the SSE service, thereby gaining unauthorized access to sensitive data. This can lead to potential system compromise or data leakage if the exposed information is of high value.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how an attacker might exploit this vulnerability:<\/p>\n

GET \/sse\/service HTTP\/1.1\nHost: vulnerable-db.example.com\nAccept: text\/event-stream\n{ \"malicious_payload\": \"stealSensitiveData()\" }<\/code><\/pre>\n
In this example, the attacker sends a GET request to the SSE service and injects a malicious payload designed to steal sensitive data.<\/p>\n
Mitigation<\/strong><\/p>\n
The best mitigation strategy to address this vulnerability is to apply the vendor-supplied patch. If this is not immediately feasible, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and\/or block malicious requests targeting the SSE service in MariaDB MCP 0.1.0.<\/p>\n","protected":false},"excerpt":{"rendered":"
