LANTRONIX SLC8000 — Lantronix Autonomous Out-of-Band Devices OS Command Injection via set script schedule

CVSS 9.4 (CNA)9.4 / 10 × 3028.2 Not in CISA KEV+300.0 EPSS percentile 76.6.766 × 2015.3 No public exploit+100.0 SSVC exploitation: none+100.0

Description · from the CVE record

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 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.
