According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.28. It is, therefore, affected by multiple vulnerabilities :
A flaw exists in the parse_url() function due to returning the incorrect host. An unauthenticated, remote attacker can exploit this to have a multiple impacts depending on how the function is implemented, which can include bypassing authentication or conducting open redirection and server-side request forgery attacks.
An integer overflow condition exists in the
_php_imap_mail() function in file ext/imap/php_imap.c when handling overly long strings. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
A flaw exists in the bzcompress() function when handling overly long strings. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.
An integer overflow condition exists in the gdImageAALine() function within file ext/gd/libgd/gd.c due to improper validation of line limit values. An unauthenticated, remote attacker can exploit this to cause an out-of-bounds memory read or write, resulting in a denial of service condition, the disclosure of memory contents, or the execution of arbitrary code.
A denial of service flaw exists due to a flaw in Zend/zend_exceptions.c via a crafted Exception object in serialized data (CVE-2016-7478)
A Stack consumption vulnerability in the gdImageFillToBorder function in gd.c in the GD Graphics Library could lead to a denial of service condition.
(CVE-2016-9933)
A denial of service flaw exists due to a flaw in ext/wddx/wddx.c via a crafted serialized data in a wddxPacket XML document. (CVE-2016-9934)
Note that this software is reportedly affected by other vulnerabilities as well that have not been fixed yet in version 5.6.28.
