| Detailed Description |
According to its banner, the version of PHP 7.0.x installed on the remote host is a version prior to 7.0.15 The PHP versions are affected by multiple vulnerabilities :
- A remote code execution vulnerability exists due to a use-after-free error in the unserialize() function that is triggered when using DateInterval input. An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-2787)
- A use-after-free error exists that is triggered when handling unserialized object properties. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary code. (CVE-2016-7479)
- An integer overflow condition exists in the _zend_hash_init() function in zend_hash.c due to improper validation of unserialized objects. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-5340)
- A floating pointer exception flaw exists in the exif_convert_any_to_int() function in exif.c that is triggered when handling TIFF and JPEG image tags. An unauthenticated, remote attacker can exploit this to cause a crash, esulting in a denial of service condition. (CVE-2016-10158)
- An integer overflow condition exists in the phar_parse_pharfile() function in phar.c due to improper validation when handling phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10159)
- An off-by-one overflow condition exists in the phar_parse_pharfile() function in phar.c due to improper parsing of phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10160)
- An out-of-bounds read error exists in the finish_nested_data() function in var_unserializer.c due to improper validation of unserialized data. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition or the disclosure of memory contents. (CVE-2016-10161)
- A NULL pointer dereference flaw exists in the php_wddx_pop_element() function in wddx.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10162)
* Note: This check solely relied on the version number of the remote PHP to assess this vulnerability, so this might be a false positive.
