AI risk analysis
- Summary
- This vulnerability allows authenticated attackers to execute arbitrary shell commands as root, leading to a complete loss of confidentiality, integrity, and availability of the device.
- Exploitability
- Exploitation requires authentication as any user with access to the terminal or CLI interface. The vulnerability is present due to unsanitized user input passed to a system() call.
- Blast radius
- If exploited, the attacker can impact the affected device and potentially downstream serial-attached devices, leading to significant damage.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to firmware v9.7.0.2 or later for SLC8000/SLC9000, v9.7.0.1 or later for EMG8500/EMG7500, and ensure all SLB882/SLCx-03/SLCx-02 firmware versions are patched.

NVD description
Lantronix SLC8000/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 to execute arbitrary shell commands as root by exploiting an undocumented mfc eeprom read command that passes unsanitized user input to a system() call. Attackers can authenticate as any user 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.
