The version of openssl11 installed on the remote host is prior to 1.1.1g-12. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1815 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. 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 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n).
Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd). (CVE-2022-1292)
