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.

Impact

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 CWE‑78 Operating System 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.

Affected Systems

Affected are Lantronix SLC8000 devices running firmware versions prior to 9.7.0.3, SLC9000 devices running firmware prior to 9.7.0.2, EMG8500 and EMG7500 devices with firmware before 9.7.0.1, and all firmware releases of SLB882, SLCx‑03 and SLCx‑02.

Risk and Exploitability

The vulnerability carries a CVSS score of 9.4, indicating critical severity. EPSS score is 2% and the flaw is not listed in the CISA KEV catalog. The attack requires authenticated access with services permission, so the likely vector is an insider or privileged user compromising the terminal or CLI interface to inject malicious commands.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the vendor’s firmware update that addresses the CWE‑78 command injection vulnerability.
  • Limit the services permission to trusted administrators only, reducing the ability to exploit the CWE‑78 vulnerability.
  • Monitor system logs for anomalous command executions that could indicate exploitation of the CWE‑78 flaw and investigate promptly.
