CVE-2025-67038 — Lantronix EDS5000 Code Injection Vulnerability

Critical CVSS 9.8 CISA KEV

An issue was discovered in Lantronix EDS5000 2.1.0.0R3. The HTTP RPC module executes a shell command to write logs when user's authantication fails. The username is directly concatenated with the command without any sanitization. This allow attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
