"The version of jettison installed on the remote host is prior to 1.3.3-4. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2023-2086 advisory.

  - Those using Jettison to parse untrusted XML or JSON data may be vulnerable to Denial of Service attacks
    (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the
    parser to crash by Out of memory. This effect may support a denial of service attack. (CVE-2022-40150)

  - A stack overflow in Jettison before v1.5.2 allows attackers to cause a Denial of Service (DoS) via crafted
    JSON data. (CVE-2022-45685)

  - Jettison before v1.5.2 was discovered to contain a stack overflow via the map parameter. This
    vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted string. (CVE-2022-45693)

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