9.1 CRITICALPublished 2026-09-22 · Updated 2026-09-26
AI risk analysis
- Summary
- The flaw allows authenticated attackers with services permission to execute arbitrary shell commands as root, leading to complete loss of confidentiality, integrity, and availability.
- Exploitability
- Exploitation is relatively straightforward for attackers with services permission, as the vulnerability involves a command injection flaw in the set script schedule command.
- Blast radius
- If exploited, the impact is severe, as it can lead to complete loss of confidentiality, integrity, and availability on the affected device and potentially impact downstream serial-attached devices.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to firmware v9.7.0.3 or later for SLC8000, v9.7.0.2 or later for SLC9000, v9.7.0.1 or later for EMG8500/EMG7500, and ensure all SLB882/SLCx-03/SLCx-02 devices are patched to the latest version.

NVD 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 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.
