CVE-2026-80144: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in LANTRONIX SLC8000
Lantronix SLC8000 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 write 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.
AI Analysis
Technical Summary
Lantronix SLC8000 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 an OS command injection vulnerability (CVE-2026-80144). The flaw arises from an undocumented mfc eeprom write command that forwards unsanitized user input directly to a system() call. Authenticated users with any account can exploit this to execute arbitrary shell commands with root privileges via the terminal or CLI interface. This vulnerability enables attackers to fully compromise the device's confidentiality, integrity, and availability, and potentially impact downstream serial-attached devices.
Potential Impact
Exploitation allows authenticated attackers to execute arbitrary commands as root, resulting in total compromise of the affected device's confidentiality, integrity, and availability. This can also affect downstream serial-attached devices connected to the vulnerable hardware.
Mitigation Recommendations
No explicit patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the terminal or CLI interfaces to trusted users only and monitor for unauthorized access attempts.
