  'Description'=> %q{
  This module exploits a PHP code injection in SPIP. The vulnerability exists in the
  connect parameter and allows an unauthenticated user to execute arbitrary commands
  with web user privileges. Branchs 2.0, 2.1 and 3 are concerned. Vulnerable versions
  are <2.0.21, <2.1.16 and < 3.0.3, but this module works only against branch 2.0 and
  has been tested successfully with SPIP 2.0.11 and SPIP 2.0.20 with Apache on Ubuntu
  and Fedora linux distributions.
