According to its banner, the version of PHP running on the remote web server is 5.4.x prior to 5.4.44. It is, therefore, affected by multiple vulnerabilities:
Multiple use-after-free vulnerabilities exist in the SPL component, due to improper handling of a specially crafted serialized object. An unauthenticated, remote attack can exploit this, via vectors involving ArrayObject, splObjectStorage and SplDoublyLinkedList to execute arbitrary code. (CVE-2015-6831)
A use-after-free vulnerability exists in ext/spl/spl_array.c due to improper handling of a specially crafted serialized data. An unauthenticated, remote attacker can exploit this via specially crafted serialized data that triggers misuse of an array field to execute arbitrary code. (CVE-2015-6832)
A directory traversal vulnerability exists in the PharData class, due to improper implementation of the exctractTo function. An unauthenticated, remote attacker can exploit this via a crafted ZIP archive entry to write to arbitrary files. (CVE-2015-6833)
The openssl_random_pseudo_bytes() function in file openssl.c does not generate sufficiently random numbers.
An unauthenticated, remote attacker can exploit this to defeat cryptographic protection mechanisms.
(CVE-2015-8867)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
