"The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by
multiple vulnerabilities:

  - A vulnerability in the kjd/idna library, specifically within the idna.encode() function, allows crafted
    input strings to cause quadratic complexity, leading to a denial of service condition. (CVE-2024-3651)

  - The CPython email module does not properly quote newlines for email headers when serializing an email
    message, allowing for header injection. (CVE-2024-6923)

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