What is CVE-2026-80151?
CVE-2026-80151 is a critical command injection vulnerability in LANTRONIX EMG7500, published on 22 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
Lantronix SLC8000 before firmware v9.7.0.3, SLC9000 before firmware v9.7.0.2, 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.
