Description

This module writes to the sudoers file without root access by exploiting rsh and malloc log files. Makes sudo require no password, giving access to su even if root is disabled. Works on OS X 10.9.5 to 10.10.5 (patched on 10.11).

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/osx/local/rsh_libmalloc
msf exploit(rsh_libmalloc) > show targets
    ...targets...
msf exploit(rsh_libmalloc) > set TARGET < target-id >
msf exploit(rsh_libmalloc) > show options
    ...show and set options...
msf exploit(rsh_libmalloc) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
