The version of Firefox installed on the remote Windows host is prior to 78.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-24 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
