Discovered by XlabAITeam, the vulnerability enables an attacker to upload arbitrary files to the server using path traversal techniques. The identified proof-of-concept exploit leverages this flaw to upload a reverse shell payload to a predictable location by traversing directories to the pip installation path. Successful exploitation allows remote code execution on the MindsDB server, potentially leading to full system compromise. The exploit specifically targets Python 3.10, but older versions may be vulnerable with slight modifications to the file path.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker gains network access to the vulnerable MindsDB instance, typically running on port 47334.\u003c/li\u003e\n\u003cli\u003eIf authentication is enabled, the attacker attempts to authenticate using known or default credentials, or exploits an authentication bypass.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious Python reverse shell payload designed to connect back to the attacker's machine.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the path traversal vulnerability to upload the reverse shell payload to the MindsDB server's file system, targeting the \u003ccode\u003ePIP_PATH\u003c/code\u003e location (e.g., \u003ccode\u003e../../../venv/lib/python3.10/site-packages/pip/__init__.py\u003c/code\u003e).\u003c/li\u003e\n\u003cli\u003eThe attacker uploads the payload using a PUT request to \u003ccode\u003e/api/files/{filename}\u003c/code\u003e with a crafted \u003ccode\u003efile\u003c/code\u003e parameter referencing the path traversal and reverse shell payload.\u003c/li\u003e\n\u003cli\u003eThe attacker triggers the execution of the uploaded payload by sending a POST request to \u003ccode\u003e/api/handlers/{HANDLER}/install\u003c/code\u003e (where HANDLER is typically \u003ccode\u003eanomaly_detection\u003c/code\u003e).\u003c/li\u003e\n\u003cli\u003eThe MindsDB server executes the uploaded Python script, initiating a reverse shell connection back to the attacker.\u003c/li\u003e\n\u003cli\u003eThe attacker gains a shell on the MindsDB server and can execute arbitrary commands, potentially leading to data exfiltration, lateral movement, or further compromise.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this path traversal vulnerability grants the attacker remote code execution capabilities on the MindsDB server.
