"The version of python3 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-7592 advisory.

  - There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library
    module. When parsing cookies that contained backslashes for quoted characters in the cookie value, the
    parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used
    while parsing the value. (CVE-2024-7592)

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