According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.34. It is, therefore, affected by multiple vulnerabilities :
A buffer over-write condition exists in the finfo_open() function due to improper validation of magic files. An unauthenticated, remote attacker can exploit this, via a crafted file, to cause a denial of service or to execute arbitrary code. (CVE-2015-8865)
An integer overflow condition exists in the php_raw_url_encode() function within file ext/standard/url.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact.
(CVE-2016-4070)
A flaw exists in the php_snmp_error() function within file ext/snmp/snmp.c that is triggered when handling format string specifiers. An unauthenticated, remote attacker can exploit this, via a crafted SNMP object, to cause a denial of service or to execute arbitrary code. (CVE-2016-4071)
An invalid memory write error exists when handling the path of phar file names that allows an attacker to have an unspecified impact. (CVE-2016-4072)
A flaw exists in the mbfl_strcut() function within file ext/mbstring/libmbfl/mbfl/mbfilter.c when handling negative parameter values. An unauthenticated, remote attacker can exploit this to cause a denial of service.
(CVE-2016-4073)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
