According to its banner, the version of PHP 5.5.x running on the remote web server is prior to 5.5.25. It is, therefore, affected by multiple vulnerabilities :

  - A flaw in the phar_parse_tarfile function in     ext/phar/tar.c could allow a denial of service     via a crafted entry in a tar archive.
    (CVE-2015-4021)

  - An integer overflow condition exists in the     ftp_genlist() function in ftp.c due to improper     validation of user-supplied input. A remote attacker can     exploit this to cause a heap-based buffer overflow,     resulting in a denial of service condition or possible     remote code execution. (CVE-2015-4022)

  - Multiple flaws exist related to using pathnames     containing NULL bytes. A remote attacker can exploit     these flaws, by combining the '\0' character with a safe     file extension, to bypass access restrictions. This had     been previously fixed but was reintroduced by a     regression in versions 5.4+. (CVE-2006-7243,     CVE-2015-4025)

  - A flaw exists in the multipart_buffer_headers() function     in rfc1867.c due to improper handling of     multipart/form-data in HTTP requests. A remote attacker     can exploit this flaw to cause a consumption of CPU     resources, resulting in a denial of service condition.
    (CVE-2015-4024)

  - A security bypass vulnerability exists due to a flaw in     the pcntl_exec implementation that truncates a pathname     upon encountering the '\x00' character. A remote     attacker can exploit this, via a crafted first argument,     to bypass intended extension restrictions and execute     arbitrary files. (CVE-2015-4026)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
