          "value": "0day Rubbish Research Team is publicly disclosing a vulnerability in nanoDLP stable build #10729 (Nano3Dtech). The \nresearch is published and a proof-of-concept is available.\n\nPre-authentication RCE (CVSS 9.8, pre-authentication)\n\nnanoDLP exposes an unauthenticated remote code execution vulnerability. The Guest (unauthenticated) endpoint POST \n/formula evaluates user-supplied JavaScript in an embedded Otto JS sandbox, which exposes a live nanoDLP domain object \nvia nanodlpContext(). The Config object is a cross-request shared live pointer; Config.ShieldUnpause is writable, and \nConfig.Save() persists it to db/machine.json without sanitization. An attacker injects [[Exec <cmd>]] into \nShieldUnpause, then the also-unauthenticated GET /printer/unpause triggers the print engine to execute the G-code, \nreaching os/exec with shell semantics as root. Dynamically verified with uid=0(root).\n\nImpact: Full read of the host filesystem and configuration as root, arbitrary OS command execution, and full control of \nthe print server and host. The injected G-code is persisted and re-executes on every unpause.\n\nAdvisory: https://0day-rubbish.com/blog/nanodlp-unauth-gcode-injection-rce\n\nPoC and full analysis: https://github.com/Exploit-Garbage/0day-Rubbish\n\n-- \n0day Rubbish Research Team\nhttps://0day-rubbish.com\n_______________________________________________\nSent through the Full Disclosure mailing list\nhttps://nmap.org/mailman/listinfo/fulldisclosure\nWeb Archives & RSS: https://seclists.org/fulldisclosure/"
