According to its version, the iCloud application installed on the remote Windows host is 10.x prior to 10.8. It is, therefore, affected by multiple vulnerabilities:

  - Multiple arbitrary code execution vulnerabilities exist with in the WebKit due to multiple memory     corruption issues. An unauthenticated, remote attacker can exploit this to execute arbitrary code.     (CVE-2019-8710, CVE-2019-8766, CVE-2019-8782, CVE-2019-8783, CVE-2019-8784, CVE-2019-8811, CVE-2019-8814,     CVE-2019-8816, CVE-2019-8819, CVE-2019-8820, CVE-2019-8821, CVE-2019-8822, CVE-2019-8823)

  - Multiple issues exist with in the Libxslt due to multiple memory corruption issue. (CVE-2019-8750)

  - An cross site scripting vulnerability exist with in the WebKit due to logic issue. An unauthenticated,     remote attacker can exploit this by processing maliciously crafted web content may lead to universal     cross site scripting. (CVE-2019-8813)

  - An arbitrary code execution vulnerability exist with in the WebKit due to multiple memory corruption     issue. An unauthenticated, remote attacker can exploit this by processing maliciously crafted web     content may lead to arbitrary code execution. (CVE-2019-8815)

The version of Apple iOS running on the mobile device is prior to 13.1. It is, therefore, affected by multiple vulnerabilities including the following: 

  - A memory corruption vulnerability was addressed with improved locking. This issue is fixed in iOS 13.1 and     iPadOS 13.1, watchOS 6, tvOS 13. An application may be able to execute arbitrary code with kernel     privileges. (CVE-2019-8740)

  - A memory corruption issue was addressed with improved memory handling. This issue is fixed in macOS     Catalina 10.15, iOS 13.1 and iPadOS 13.1, tvOS 13, macOS Catalina 10.15.1, Security Update 2019-001, and     Security Update 2019-006, watchOS 6. An application may be able to execute arbitrary code with system     privileges. (CVE-2019-8831)

  - A memory corruption vulnerability was addressed with improved locking. This issue is fixed in watchOS 6.1.
    An application may be able to execute arbitrary code with kernel privileges. (CVE-2019-8747)

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

The remote host is running a version of macOS or Mac OS X that is 10.15.x prior to 10.15.1, 10.14.x prior to 10.14.6 security update 2019-001, 10.13.x prior to 10.13.6 security update 2019-006. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the accounts component due to improper input validation. A remote     attacker can exploit this, to disclose memory contents. (CVE-2019-8787)

  - A security bypass vulnerability exists in the App Store component due to an improper state management     implementation. A local attacker can exploit this, to login to the account of a previously logged in user     without valid credentials. (CVE-2019-8803)

  - An out-of-bounds read error exists in the IOGraphics component due to improper bounds checking. A local     attacker can exploit this, to cause unexpected system termination or to read kernel memory.     (CVE-2019-8759)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.
