According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.9. 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. (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 flaw exists in the curl_unescape() function within file ext/curl/interface.c when handling string lengths. An unauthenticated, remote attacker can exploit this to cause heap corruption, resulting in a denial of service condition.
A heap-based buffer overflow condition exists in the mcrypt_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.
Note that the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
