Executive brief
Alibaba Cloud RDS OpenAPI MCP Server is a tool used to manage cloud database services. A security flaw in its default configuration allows the server to listen on all network interfaces, potentially exposing management tools to unauthorized users over the network. This could allow an attacker to view sensitive information or interact with database management functions without proper authorization.
Technical details
The alibabacloud-rds-openapi-mcp-server suffers from an insecure default initialization (CWE-1188) where the Model Context Protocol (MCP) server binds to all available network interfaces (0.0.0.0) by default. This improper exposure allows unauthenticated remote attackers with network access to the endpoint to invoke exposed MCP tools. The vulnerability is present in versions 1.8.0 through 3.1.2. An exploit could lead to unauthorized information disclosure or interaction with the RDS OpenAPI functions integrated into the MCP server.
