CVE-2026-80152: 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 script schedule 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
Lantronix SLC8000 and related devices contain an OS command injection vulnerability (CVE-2026-80152) due to improper neutralization of special elements in the set script schedule command. Authenticated users with services permission can inject arbitrary shell commands as root because the input is passed unsanitized to a system() call. Affected firmware versions include all versions of SLB882, SLCx-03, SLCx-02, and versions prior to 9.7.0.3 for SLC8000 and prior to 9.7.0.1 for EMG8500/EMG7500. Exploitation can result in complete device compromise and impact downstream serial-attached devices.
Potential Impact
Successful exploitation allows authenticated attackers with services permission to execute arbitrary commands as root, resulting in complete loss of confidentiality, integrity, and availability of the affected device. This may also affect downstream serial-attached devices connected to the compromised device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, restrict access to users with services permission and monitor for unauthorized command execution attempts. Avoid exposing management interfaces to untrusted networks.
