According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.14. It is, therefore, affected by the following vulnerabilities:
A remote code execution vulnerability due to a memory corruption issue in the php_wddx_push_element() function in ext/wddx/wddx.c that occurs when decoding empty boolean elements. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-9935)
A deserialization vulnerability exists in the ext/standard/var.c script. An unauthenticated, remote attacker can exploit this, via crafted serialized data, to the application to stop responding or execute arbitrary code on the target host. (CVE-2016-9936)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
