Summary
Fleet Affected by Local Privilege Escalation via Tcl Command Injection in Orbit
Details

Summary

The Orbit agent's FileVault disk encryption key rotation flow on collects a local user's password via a GUI dialog and interpolates it directly into a Tcl/expect script executed via exec.Command("expect", "-c", script). Because the password is inserted into Tcl brace-quoted send {%s}, a password containing } terminates the literal and injects arbitrary Tcl commands. Since Orbit runs as root, this allows a local unprivileged user to escalate to root privileges.

CWE

  • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
  • CWE-94: Improper Control of Generation of Code ('Code Injection')

Impact

  • Local privilege escalation to root: Any unprivileged local user on a managed endpoint can execute arbitrary commands as root
