The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 4eeb93bf-f204-11ec-8fbd-d4c9ef517024 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the 4eeb93bf-f204-11ec-8fbd-d4c9ef517024 advisory.
- In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances
where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection
were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other
places in the script where the file names of certificates being hashed were possibly passed to a command
executed through the shell. This script is distributed by some operating systems in a manner where it is
automatically executed. On such operating systems, an attacker could execute arbitrary commands with the
privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the
OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in
OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze). (CVE-2022-2068)
