Versions of PHP 5.5.x prior to 5.5.37, or 5.6.x prior to 5.6.23, or 7.0.x prior to 7.0.8 are vulnerable to the following issues :

 - PHP 'ext/mysqlnd/mysqlnd.c' contains a flaw that is due to the program failing to properly enforce the requirement of an SSL/TLS connection when the '--ssl client' option is used. This may allow a MitM (Man-in-the-Middle) attacker to downgrade the connection to plain HTTP when expected to be HTTPS. (CVE-2015-8838)
 - An integer overflow condition exists in the 'getFromIndex()'' and 'getFromName()' methods of 'ZipArchive'. The issue is triggered as user-supplied input is not properly validated when handling a specially crafted ZIP file.

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.22. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the
    _gdContributionsCalc() function within file     ext/gd/libgd/gd_interpolation.c. An unauthenticated,     remote attacker can exploit this to disclose sensitive     information or crash the process linked against the     library. (CVE-2013-7456)

  - An out-of-bounds read error exists in the     get_icu_value_internal() function within file     ext/intl/locale/locale_methods.c due to improper     handling of user-supplied input. An unauthenticated,     remote attacker can exploit this to disclose sensitive     information or crash the process linked against the     library. (CVE-2016-5093)

  - An integer overflow condition exists in the     php_html_entities() and php_filter_full_special_chars()     functions within file ext/standard/html.c due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     have an unspecified impact. (CVE-2016-5094)

  - An integer underflow condition exists in file     ext/standard/file.c due to improper validation of     user-supplied input. An unauthenticated, remote     attacker can exploit this to cause a NULL write,     resulting in crashing the process linked against the     library. (CVE-2016-5096)

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

According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.36. It is, therefore, affected by multiple vulnerabilities :
