Title
Security advisory: Pre-authentication RCE in nanoDLP stable build #10729 (Nano3Dtech)
Summary
0day Rubbish Research Team is publicly disclosing a vulnerability in nanoDLP stable build #10729 (Nano3Dtech). The research is published and a proof-of-concept is available. Pre-authentication RCE (CVSS 9.8, pre-authentication) nanoDLP exposes an unauthenticated remote code execution vulnerability. The Guest (unauthenticated) endpoint POST /formula evaluates user-supplied JavaScript in an embedded Otto JS sandbox, which exposes a live nanoDLP domain object via nanodlpContext(). The Config object is a cross-request shared live pointer; Config.ShieldUnpause is writable, and Config.Save() persists it to db/machine.json without sanitization. An attacker injects [[Exec <cmd>]] into ShieldUnpause, then the also-unauthenticated GET /printer/unpause triggers the print engine to execute the G-code, reaching os/exec with shell semantics as root. Dynamically verified with uid=0(root). Impact: Full read of the host filesystem and configuration as root, arbitrary OS command execution, and full control of the print server and host. The injected G-code is persisted and re-executes on every unpause.
