제출 #784864: elgentos magento2-dev-mcp <=1.0.2 Command Injection

A command injection vulnerability exists in elgentos/magento2-dev-mcp due to unsafe use of child_process.execAsync when constructing Magerun2 CLI commands with user-controlled input. Successful exploitation allows attackers to execute arbitrary shell commands with the privileges of the MCP server process. The following MCP tools construct command strings using user-supplied parameters and execute them via child_process.execAsync:
 config-show: interpolates path, scope, and scopeId parameters
 config-set: interpolates path, value, scope, and scopeId parameters
 config-store-get: interpolates path and storeId parameters
 config-store-set: interpolates path, value, and storeId parameters
 cache-view: interpolates key and type parameters
 db-query: interpolates query parameter
 dev-module-observer-list: interpolates event parameter
 dev-module-create: interpolates vendorNamespace, moduleName, authorName, authorEmail, and description parameters
 setup-static-content-deploy: interpolates languages and themes parameters
 sys-url-list: interpolates storeId parameter
 sys-cron-run: interpolates job and group parameters
Because execAsync invokes commands through a system shell, specially crafted input containing shell metacharacters (such as `;`, `&`, or `|`) may be interpreted as additional commands rather than treated as data.
For example, an attacker could supply a malicious value in key to inject arbitrary shell commands, which would then be executed with the privileges of the MCP server process.
The vulnerability results from shell-based command execution combined with direct interpolation of untrusted input. In MCP environments, LLM-generated tool parameters influenced by external content may trigger execution of injected commands without direct local user interaction.
