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.
