According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.24. It is, therefore, affected by multiple vulnerabilities :

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. An unauthenticated, remote attacker can exploit     this, via a crafted 'Proxy' header in an HTTP request,     to redirect an application's internal HTTP traffic to an     arbitrary proxy server where it may be observed or     manipulated. (CVE-2016-5385)

  - An overflow condition exists in the php_bz2iop_read()     function within file ext/bz2/bz2.c due to improper     handling of error conditions. An unauthenticated, remote     attacker can exploit this, via a crafted request, to     execute arbitrary code. (CVE-2016-5399)

  - A flaw exists in the GD Graphics Library (libgd),     specifically in the gdImageScaleTwoPass() function     within file gd_interpolation.c, due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition. (CVE-2016-6207)

  - An integer overflow condition exists in the     virtual_file_ex() function within file     Zend/zend_virtual_cwd.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code. (CVE-2016-6289)

  - A use-after-free error exists within the file     ext/session/session.c when handling 'var_hash'     destruction. An unauthenticated, remote attacker can     exploit this to deference already freed memory,     resulting in the execution of arbitrary code.
    (CVE-2016-6290)

  - An out-of-bounds read error exists in the     exif_process_IFD_in_MAKERNOTE() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     disclose memory contents. (CVE-2016-6291)

  - A NULL pointer dereference flaw exists in the     exif_process_user_comment() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.

According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.38. It is, therefore, affected by multiple vulnerabilities :

  - A Segfault condition occurs when accessing     nvarchar(max) defined columns. (CVE-2015-8879)

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. An unauthenticated, remote attacker can exploit     this, via a crafted 'Proxy' header in an HTTP request,     to redirect an application's internal HTTP traffic to an     arbitrary proxy server where it may be observed or     manipulated. (CVE-2016-5385)

  - An overflow condition exists in the php_bz2iop_read()     function within file ext/bz2/bz2.c due to improper     handling of error conditions. An unauthenticated, remote     attacker can exploit this, via a crafted request, to     execute arbitrary code. (CVE-2016-5399)

  - A flaw exists in the GD Graphics Library (libgd),     specifically in the gdImageScaleTwoPass() function     within file gd_interpolation.c, due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition. (CVE-2016-6207)

  - A buffer overflow condition exists in the     php_url_parse_ex() function. (CVE-2016-6288)

  - An integer overflow condition exists in the     virtual_file_ex() function within file     Zend/zend_virtual_cwd.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code. (CVE-2016-6289)

  - A use-after-free error exists within the file     ext/session/session.c when handling 'var_hash'     destruction. An unauthenticated, remote attacker can     exploit this to deference already freed memory,     resulting in the execution of arbitrary code.
    (CVE-2016-6290)

  - An out-of-bounds read error exists in the     exif_process_IFD_in_MAKERNOTE() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     disclose memory contents. (CVE-2016-6291)

  - A NULL pointer dereference flaw exists in the     exif_process_user_comment() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.
    (CVE-2016-6292)

  - Multiple out-of-bounds read errors exist in the     locale_accept_from_http() function within file     ext/intl/locale/locale_methods.c. An unauthenticated,     remote attacker can exploit these to cause a denial of     service condition or disclose memory contents.
    (CVE-2016-6293, CVE-2016-6294)

  - A use-after-free error exists within file     ext/snmp/snmp.c when handling garbage collection during     deserialization of user-supplied input. An     unauthenticated, remote attacker can exploit this to     deference already freed memory, resulting in the     execution of arbitrary code. (CVE-2016-6295)

  - A heap-based buffer overflow condition exists in the     simplestring_addn() function within file simplestring.c     due to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-6296)

  - An integer overflow condition exists in the     php_stream_zip_opener() function within file     ext/zip/zip_stream.c due to improper validation of     user-supplied input when handling zip streams. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-6297)

  - An out-of-bounds read error exists in the GD Graphics     Library (libgd), specifically in the     gdImageScaleBilinearPalette() function within file     gd_interpolation.c, when handling transparent color. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or disclose     memory contents.

  - A heap-based buffer overflow condition exists in the     mdecrypt_generic() function within file     ext/mcrypt/mcrypt.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code.

  - A NULL write flaw exists in the GD Graphics Library     (libgd) in the gdImageColorTransparent() function due to     improper handling of negative transparent colors. A     remote attacker can exploit this to disclose memory     contents.

  - An overflow condition exists in the php_url_prase_ex()     function due to improper validation of user-supplied     input. A remote attacker can exploit this to cause a     buffer overflow, resulting in a denial of service     condition.

Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development.
