vulnerability as referenced in the DSA-2021-177 advisory:

  - iDRAC9 versions prior to 5.00.00.00 contain an improper input validation vulnerability. An unauthenticated
    remote attacker may potentially exploit this vulnerability by sending a specially crafted malicious
    request to crash the webserver or cause information disclosure. (CVE-2021-36300)

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