Summary
electerm has Command Injection in File System Operations (rmrf, mv, cp)
Details

Impact

A command injection vulnerability exists in electerm's file system operations (rmrf, mv, cp) in src/app/lib/fs.js. These functions construct shell commands by interpolating file paths directly into command strings without escaping shell metacharacters.

Vulnerable functions:

  • rmrf() - Uses rm -rf "${path}" (double quotes, vulnerable to " injection)
  • mv() - Uses mv '${from}' '${to}' (single quotes, vulnerable to ' injection)
  • cp() - Uses cp -r "${from}" "${to}" (double quotes, vulnerable to " injection)

Attack scenario:

  1. Attacker controls a malicious SSH/SFTP server
  2. Server lists files with shell metacharacters in names (e.g., file"$(touch /tmp/pwned)")
  3. Victim connects to the server and performs file operations (remote-to-local transfer, rename on conflict, etc.)
  4. The malicious filename is passed to rmrf(), mv(), or cp() without sanitization
  5. Shell metacharacters break out of the quoted argument and execute arbitrary commands

Impact includes:

  • Arbitrary command execution as the electerm desktop user
  • Data exfiltration, malware installation, or system compromise
  • Both POSIX (bash) and Windows (PowerShell) platforms are affected

Patches

Workarounds

If upgrading is not immediately possible, users can mitigate this vulnerability by:

  1. Only connecting to trusted SSH/SFTP servers
  2. Avoiding remote-to-local file transfers from untrusted sources
  3. Not using the "rename on conflict" option when downloading folders from untrusted servers
  4. Manually verifying filenames before performing file operations
