The version of Wireshark installed on the remote Windows host is prior to 3.2.18. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-3.2.18 advisory.
The Bluetooth DHT dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
(CVE-2021-39929)
The Bluetooth SDP dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
(CVE-2021-39925)
The Bluetooth DHT dissector could go into a large loop It may be possible to make Wireshark consume excessive CPU resources by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. (CVE-2021-39924)
The C12.22 dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. (CVE-2021-39922)
The IEEE 802.11 dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. (CVE-2021-39928)
The Modbuss dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. (CVE-2021-39921)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
