"The version of Junos OS installed on the remote host is affected by a vulnerability as referenced in the JSA69505
advisory.

  - An Improper Check for Unusual or Exceptional Conditions vulnerability in the packetIO daemon of Juniper Networks 
    Junos OS Evolved on PTX10003, PTX10004, and PTX10008 allows an unauthenticated, network-based attacker to cause 
    a Denial of Service (DoS). Continued receipt of these crafted packets will cause a sustained Denial of Service 
    condition. This issue affects Juniper Networks Junos OS Evolved all versions prior to 20.4R2-S3-EVO on PTX10003, 
    PTX10004, and PTX10008. This issue does not affect: Juniper Networks Junos OS Evolved versions 21.1R1-EVO and 
    above; Juniper Networks Junos OS. (CVE-2022-22194)

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