"The version of python2 / python3 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the CVE-2015-20107 advisory.

  - In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands
    discovered in the system mailcap file. This may allow attackers to inject shell commands into applications
    that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or
    arguments). The fix is also back-ported to 3.7, 3.8, 3.9 (CVE-2015-20107)

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