CyberRota Analysis
AI-GeneratedThe vulnerability in 9router version 0.4.59 allows remote, unauthenticated attackers to exploit a hardcoded default password, bypass local network restrictions, and execute arbitrary code through malicious MCP plugins. This critical flaw poses a severe risk as it enables complete system compromise upon triggering the plugin's SSE endpoint. Organizations using this version should prioritize immediate updates to version 0.4.60 to mitigate the risk of exploitation.

Original NVD Description
9router 0.4.59 (fixed in 0.4.60) contains a chain of vulnerabilities: a hardcoded default password (123456) that authenticates any fresh installation, a bypass of the LOCAL_ONLY network gate via a spoofed Host header, and unvalidated arguments passed to child_process.spawn() when registering MCP plugins. A remote, unauthenticated attacker can log in with the default credential, spoof the Host header to reach local-only routes, and register a malicious MCP plugin (e.g. node -e <payload>) to achieve arbitrary code execution on the host operating system when the plugin's SSE endpoint is triggered.
