"The remote NewStart CGSL host, running version MAIN 5.04, has openssl packages installed that are affected by a
vulnerability:

  - 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)

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