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.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - University of Washington IMAP Toolkit 2007f on UNIX, as used in imap_open() in PHP and other products,
    launches an rsh command (by means of the imap_rimap function in c-client/imap4r1.c and the tcp_aopen
    function in osdep/unix/tcp_unix.c) without preventing argument injection, which might allow remote
    attackers to execute arbitrary OS commands if the IMAP server name is untrusted input (e.g., entered by a
    user of a web application) and if rsh has been replaced by a program with different argument semantics.
    For example, if rsh is a link to ssh (as seen on Debian and Ubuntu systems), then the attack can use an
    IMAP server name containing a "-oProxyCommand" argument. (CVE-2018-19518)

  - Integer underflow in the _gdContributionsAlloc function in gd_interpolation.c in the GD Graphics Library
    (aka libgd) before 2.2.4 allows remote attackers to have unspecified impact via vectors related to
    decrementing the u variable. (CVE-2016-10166)

  - An issue was discovered in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before
    7.2.1. There is Reflected XSS on the PHAR 404 error page via the URI of a request for a .phar file.
    (CVE-2018-5712)

  - exif_process_IFD_in_MAKERNOTE in ext/exif/exif.c in PHP before 5.6.37, 7.0.x before 7.0.31, 7.1.x before
    7.1.20, and 7.2.x before 7.2.8 allows remote attackers to cause a denial of service (out-of-bounds read
    and application crash) via a crafted JPEG file. (CVE-2018-14851)

  - An issue was discovered in PHP before 5.6.37, 7.0.x before 7.0.31, 7.1.x before 7.1.20, and 7.2.x before
    7.2.8. An Integer Overflow leads to a heap-based buffer over-read in exif_thumbnail_extract of exif.c.
