An issue was discovered in Lantronix EDS3000PS 3.1.0.0R2. The host parameter of the TFTP client in the Filesystem Browser page is not properly sanitized. This can be exploited to escape from the original command and execute an arbitrary one with root privileges.

AnalysisAI
Authenticated OS command injection in the Lantronix EDS3000PS serial device server firmware 3.1.0.0R2 allows a high-privileged attacker to execute arbitrary commands with root OS privileges via the unsanitized host parameter of the TFTP client in the Filesystem Browser page. Affected hardware variants are confirmed as the EDS3016PS1NS and EDS3008PS1NS models per CPE data. CISA issued ICS advisory ICSA-26-069-02 covering this vulnerability, indicating industrial/OT significance. No public exploit code or KEV listing is present; EPSS is 0.04% (13th percentile), reflecting low general exploitation probability but elevated concern in OT contexts where device admin credentials may be shared or weakly controlled.
Technical ContextAI
The Lantronix EDS3000PS product line is an industrial serial-to-network device server used in OT/ICS environments to connect legacy serial equipment over TCP/IP. Affected firmware versions per CPE are cpe:2.3:o:lantronix:eds3016ps1ns_firmware:3.1.0.0r2 and cpe:2.3:o:lantronix:eds3008ps1ns_firmware:3.1.0.0r2. The vulnerability is classified as CWE-78 (Improper Neutralization of Special Elements used in an OS Command). Specifically, the web-based Filesystem Browser exposes a TFTP client whose host field is passed to a shell command without adequate sanitization, permitting command separator injection (e.g., semicolons, backticks, or pipes). Because the underlying TFTP operation runs with root privileges, injected commands inherit that privilege level, achieving full OS compromise from a web interface action.
RemediationAI
Consult the Lantronix vulnerability library at https://www.lantronix.com/technical-support/security-updates/vulnerability-disclosure-policy/vulnerability-library/ and the CISA ICS advisory at https://www.cisa.gov/news-events/ics-advisories/icsa-26-069-02 for the vendor-released firmware update; no specific fixed version number is present in the available data, so a patched release version cannot be independently confirmed from this dataset. Until a patch is applied, restrict access to the device web management interface to dedicated management VLANs or jump hosts using firewall rules, eliminating network-layer reachability from untrusted segments. Rotate and enforce strong, unique administrative credentials to reduce the likelihood of credential-based pre-exploitation. Disable TFTP client functionality in the Filesystem Browser if it is not operationally required - consult the Lantronix admin guide for the relevant setting - which removes the vulnerable code path entirely with no impact on core serial-to-network functionality. Monitor device management logs for unexpected TFTP client invocations as a detection control.
