The issue was addressed with improved permissions logic. This issue is fixed in iOS 13.3.1 and iPadOS 13.3.1, macOS Catalina 10.15.3, tvOS 13.3.1, watchOS 6.1.2. An application may be able to execute arbitrary code with system privileges.

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2021-003 Mojave It is, therefore, affected by multiple vulnerabilities, including the following:

  - An application may be able to execute arbitrary code with system privileges due to insufficient permission     checks (CVE-2020-3838).

  - A memory corruption vulnerability could allow an application read access to restricted memory (CVE-2021-1808).

  - A memory corruption vulnerability could allow an application to cause unexpected system termination or to     write kernel memory (CVE-2021-1828).

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

The remote host is running a version of macOS / Mac OS X that is 10.15.x prior to 10.15.7 Security Update 2021-002 Catalina It is, therefore, affected by multiple vulnerabilities, including the following:

  - An application may be able to execute arbitrary code with system privileges due to insufficient permission     checks (CVE-2020-3838).

  - A memory corruption vulnerability could allow an application read access to restricted memory (CVE-2021-1808).

  - A memory corruption vulnerability could allow an application to cause unexpected system termination or to     write kernel memory (CVE-2021-1828).

According to its banner, the version of Apple TV on the remote device is prior to 13.3.1. It is therefore affected by multiple vulnerabilities as described in the HT210920

The remote host is running a version of macOS / Mac OS X that is 10.15.x prior to 10.15.3, 10.13.x prior to 10.13.6, 10.14.x prior to 10.14.6. It is, therefore, affected by multiple vulnerabilities:

  - In PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24     and 7.3.x below 7.3.11 in certain configurations of FPM     setup it is possible to cause FPM module to write past     allocated buffers into the space reserved for FCGI     protocol data, thus opening the possibility of remote     code execution. (CVE-2019-11043)

  - An arbitrary code exution vulnerability exists      due to a misconfiguration. An authenticated, local attacker     can exploit this to execute arbitrary code on the remote host.
    (CVE-2019-18634)

  - An arbitrary code exution vulnerability exists      due to the ability to process a maliciously crafted image.     An unauthenticated, remote attacker can exploit this to     execute arbitrary code on the remote host.
    (CVE-2020-3826 CVE-2020-3827 CVE-2020-3870 CVE-2020-3878)

  - A privilege escalation vulnerability exists in due to an out-of-bounds read issue.     An unauthenticated, remote attacker can exploit this, to gain elevated     access to the system. (CVE-2020-3829)

  - An arbitrary file write vulnerability exists in the handling of symlinks.     A malicious program crafted by an attacker can exploit this to overwrite arbitrary files on the remote host.
    (CVE-2020-3830 CVE-2020-3835 CVE-2020-3855)

  - An information disclosure vulnerability exists in the access control handling of applications.     A malicious application crafted by attacker can exploit this to disclose the kernel memory layout.
    (CVE-2020-3836)

  - An arbitrary code exution vulnerability exists      due to a memory corruption issue. A malicious application     crafted by a remote attacker may be able to execute arbitrary code     with kernel privileges on the remote host.
    (CVE-2020-3837  CVE-2020-3842 CVE-2020-3871)

  - An arbitrary code exution vulnerability exists      due to a permissions logic flaw.  A malicious application     crafted by a remote attacker may be able to execute arbitrary code     with system privileges on the remote host.
    (CVE-2019-18634 CVE-2020-3854 CVE-2020-3845 CVE-2020-3853 CVE-2020-3857)

  - An information disclosure vulnerability exists in the input sanitization logic.     A malicious application crafted by attacker can exploit this to read restricted memory.
    (CVE-2020-3839 CVE-2020-3847)

  - An arbitrary code exution vulnerability exists      due to the loading of a maliciously crafted racoon configuration file.     An authenticated, local attacker can exploit this to execute arbitrary code on the remote host.
    (CVE-2020-3840)

  - A denial of service (DoS) vulnerability exists due to a memory corruption issue. An     unauthenticated, remote attacker can exploit this issue, via malicious input, to cause the     system to crash, stop responding, or corrupt the kernel memory. (CVE-2020-3843)

  - An arbitrary code exution vulnerability exists      due to either a buffer overflow or out-of-bounds read issue. An authenticated, local attacker     can exploit this to execute arbitrary code on the remote host or     cause an unexpected application to terminate.
    (CVE-2020-3846 CVE-2020-3848 CVE-2020-3849 CVE-2020-3850 CVE-2020-3877)

  - A memory corruption vulnerability exists due to a malicious crafted string. An     unauthenticated, remote attacker can exploit this issue, via malicious input, to cause the     corruption of the heap memory. (CVE-2020-3856)

  - An security bypass vulnerability exists in the handling of files from an attacker controlled NFS mount.     A remote attacker with local access could search for and open a file from an attacker controlled NFS mount     and bypass Gatekeeper Security features. (CVE-2020-3866)

  - An information disclosure vulnerability exists where an application     can read restricted memory.  A local, authorized attacker can exploit this to read restricted memory.
    (CVE-2020-3872 CVE-2020-3875)

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

The version of Apple iOS running on the mobile device is prior to 13.3.1. It is, therefore, affected by multiple vulnerabilities.
