Publication date: 2026-03-11

Last updated on: 2026-07-05

Assigner: MITRE

Description
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.

Executive Summary

This vulnerability exists in the Lantronix EDS5000 version 2.1.0.0R3, specifically in its HTTP RPC module. When a user's authentication fails, the module attempts to write logs by executing a shell command. However, the username provided by the user is directly concatenated into this shell command without any sanitization or validation.

Because of this lack of sanitization, an attacker can inject arbitrary operating system commands into the username parameter. These injected commands are then executed with root privileges, which means the attacker can run any command on the system with the highest level of access.

Impact Analysis

This vulnerability can have severe impacts because it allows an attacker to execute arbitrary commands on the affected system with root privileges.

  • Complete system compromise by executing malicious commands.
  • Potential unauthorized access to sensitive data.
  • Disruption of service or system stability through malicious commands.
  • Installation of persistent backdoors or malware.
