According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.39, 7.0.x prior to 7.0.33, 7.1.x prior to 7.1.25, 7.2.x prior to 7.2.13 or 7.3.x prior to 7.3.0. It is, therefore, affected by multiple vulnerabilities:

  • An arbitrary command injection vulnerability exists in the imap_open function due to improper filters for mailbox names prior to passing them to rsh or ssh commands. An authenticated, remote attacker can exploit this by sending a specially crafted IMAP server name to cause the execution of arbitrary commands on the target system. (CVE-2018-19518)

  • A heap buffer over-read exists in the phar_parse_pharfile function. An unauthenticated, remote attacker can exploit this to read allocated or unallocated memory past the actual data when trying to parse a .phar file. (CVE-2018-20783)

  • A NULL pointer dereference on Windows. An unauthenticated, remote attacker can exploit this to crash the application and perform a denial of service. (CVE-2018-19395)

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