"value": "0day Rubbish Research Team is publicly disclosing two vulnerabilities in Lantronix EDS3000PR 3.2.0.0R2.\n\nVulnerability 1 — Authenticated command injection to root RCE in FsUnmount (CVSS 8.8, \nCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, CWE-78)\n\nLantronix EDS3000PR is an industrial serial device server (CII/OT). Its FsUnmount page handler validates a \nuser-supplied path against a character bitmask that rejects most shell metacharacters but allows single quotes and \nnewlines, then executes /sbin/ltrx_usb_umount '/ltrx_user<path>' via /bin/sh -c. A newline breaks out of the \nsingle-quoted command and the injected command executes as root. Verified with a root-owned marker in a qemu-arm chroot \nusing the real rootfs /bin/sh.\n\nAuthentication: authenticated (requires valid session)\n\nVulnerability 2 — Authenticated command injection to root RCE in SSL certificate import and diagnostics (CVSS 8.8, \nCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, CWE-78)\n\nOn the same Lantronix EDS3000PR device, the SSL certificate upload handler builds openssl rsa|dsa|ec|pkcs12 -passin \npass:%s commands from the attacker-controlled certificate password and executes them via system(); the diagnostics \nhandler builds ping and traceroute commands from the attacker-controlled host field the same way. No shell-character \nsanitization exists. An authenticated admin submits a semicolon or command-substitution payload in the password or host \nfield; the injected command executes as root. Verified with root markers for 5/5 SSL vectors and 3/3 diagnostics \nvectors.\n\nAuthentication: authenticated (requires valid session)\n\nFull technical analyses and reproducible proofs-of-concept:\n https://0day-rubbish.com/blog/lantronix-eds3000pr-fsunmount-command-injection\n https://0day-rubbish.com/blog/lantronix-eds3000pr-passin-pass-command-injection\n\nProject archive (ongoing disclosure series):\n https://github.com/Exploit-Garbage/0day-Rubbish\n\nVendor has been notified. CVE IDs are pending.\n\n--\n0day Rubbish Research Team\ndisclosure () 0day-rubbish com\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/"
