According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.0. It is, therefore, affected by the following vulnerabilities:
A stack consumption condition exists in the gdImageFillToBorder function of the gd.c script within the GD Graphics Library (libgd). An unauthenticated, remote attacker can exploit this issue, via a crafted call to imagefilltoborder using a negative color value, to cause the application to stop responding.
(CVE-2016-9933)
A denial of service (DoS) vulnerability exists in the ext/wddx/wddx.c script. An unauthenticated, remote attacker can exploit this issue, via crafted serialized data in a wddxPacket XML document, to cause the application to stop responding. (CVE-2016-9934)
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.
