Description
This module attempts to gain root privileges by exploiting a vulnerability in the `staprun` executable included with SystemTap version 1.3.
The `staprun` executable does not clear environment variables prior to executing `modprobe`, allowing an arbitrary configuration file to be specified in the `MODPROBE_OPTIONS` environment variable, resulting in arbitrary command execution with root privileges.
This module has been tested successfully on:
systemtap 1.2-1.fc13-i686 on Fedora 13 (i686); and systemtap 1.1-3.el5 on RHEL 5.5 (x64).
