CVE-2026-80151: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in LANTRONIX SLC8000
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.
AI Analysis
Technical Summary
The vulnerability in LANTRONIX SLC8000 and related devices arises from improper neutralization of special elements in the set nfs download command, which passes unsanitized user input to a system() call. Authenticated users with services permission can inject arbitrary shell commands executed with root privileges. Affected devices include LANTRONIX SLC8000 before firmware v9.7.0.3, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882, SLCx-03, and SLCx-02. This flaw allows attackers to compromise device confidentiality, integrity, and availability, and may also affect downstream serial-attached devices.
Potential Impact
An attacker with services permission who can authenticate to the terminal or CLI interface can execute arbitrary commands as root, leading to full compromise of the device. This includes complete loss of confidentiality, integrity, and availability of the affected device and potential impact on connected serial-attached devices.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the services permission and terminal/CLI interfaces to trusted users only to reduce risk.
