# CVE-2026-41501

> 9.8 CRITICAL · 🧪 PoC

## Beschreibung

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to version 3.3.8, a command injection vulnerability exists in github.com/elcterm/electerm/npm/install.js:130. The runLinux() function appends attacker-controlled remote version strings directly into an exec("rm -rf ...") command without validation. This issue has been patched in version 3.3.8.

## Schwachstellen-Klasse

- **CWE-77** — Improper Neutralization of Special Elements used in a Command (Command Injection)
  The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
