CVE-2026-80151: Lantronix Autonomous Out-of-Band Devices OS Command Injection via set nfs download
Lantronix SLC8000 before firmware v9.7.0.3, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882/SLCx-03/SLCx-02 contain a command injection vulnerability that allows authenticated attackers with the services permission to execute arbitrary shell commands as root by exploiting the set nfs download command that passes unsanitized user input to a system() call. Attackers with the services permission can authenticate to the terminal or CLI interface and inject malicious commands through the unsanitized parameter to achieve complete loss of confidentiality, integrity, and availability on the affected device and potentially impact downstream serial-attached devices.

Frequently Asked Questions
What level of access does an attacker need to exploit this issue?
An attacker must be able to authenticate to the affected device's terminal or CLI interface with the services permission. No user interaction is required after the attacker has that access.
Which devices have a firmware update identified in the available information?
SLC8000 devices are affected before firmware v9.7.0.3, and EMG8500 and EMG7500 devices are affected before firmware v9.7.0.1. All firmware versions of SLB882, SLCx-03, and SLCx-02 are affected according to the provided information.
What is the impact if exploitation succeeds?
The attacker can execute arbitrary shell commands as root on the device, resulting in complete compromise of confidentiality, integrity, and availability. Downstream serial-attached devices may also be affected.
How can administrators identify potentially affected systems?
Identify Lantronix devices in the listed product families and compare their installed firmware against the stated fixed versions for SLC8000, EMG8500, and EMG7500. Treat SLB882, SLCx-03, and SLCx-02 as affected regardless of firmware version.
