According to its banner, the version of PHP 4.3.x installed on the remote host is prior to 4.3.2. It is, therefore, potentially affected by an information disclosure vulnerability.
Due to a flaw in the function php_safe_mode_include_dir(), a local attacker could bypass safe mode and gain unauthorized access to files on the local system.
