According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.33. It is, therefore, affected by multiple vulnerabilities :
A use-after-free error exists in file ext/wddx/wddx.c in the php_wddx_pop_element() function when handling XML data. An unauthenticated, remote attacker can exploit this, via crafted XML data, to dereference already freed memory, resulting in the execution of arbitrary code.
(CVE-2016-3141)
An out-of-bounds read error exists in file ext/phar/zip.c in the phar_parse_zipfile() function that allows an unauthenticated, remote attacker to cause a denial of service or to gain access to sensitive information. (CVE-2016-3142)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
