"The version of Adobe ColdFusion installed on the remote Windows host is prior to 2023 update 19 or 2025 update 7. It
is, therefore, affected by multiple vulnerabilities as referenced in the APSB26-38 advisory.

  - ColdFusion versions 2023.18, 2025.6 and earlier are affected by an Improper Input Validation vulnerability
    that could result in arbitrary code execution in the context of the current user. Exploitation of this issue
    does not require user interaction. (CVE-2026-27304)

  - ColdFusion versions 2023.18, 2025.6 and earlier are affected by an Improper Limitation of a Pathname to a
    Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary file system read. An
    attacker could exploit this vulnerability to access sensitive files and directories outside the intended
    access scope. Exploitation of this issue does not require user interaction. (CVE-2026-27305)

  - ColdFusion versions 2023.18, 2025.6 and earlier are affected by an Improper Limitation of a Pathname to a
    Restricted Directory ('Path Traversal') vulnerability that could result in a Security feature bypass. An
    attacker could leverage this vulnerability to access unauthorized files or directories outside the intended
    restrictions. Exploitation of this issue does not require user interaction. (CVE-2026-34619)

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