According to its banner, the version of Apple TV on the remote device is prior to 14.6. It is therefore affected by multiple vulnerabilities as described in the HT212532, including:

  • Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2021-30665)

  • Processing a maliciously crafted audio file may lead to arbitrary code execution (CVE-2021-30707)

  • Processing maliciously crafted web content may lead to universal cross site scripting (CVE-2021-30689)

Note that Nessus has not tested for these issues but has instead relied only on the applicationโ€™s self-reported version number.
