An uncaught exception in Elasticsearch >= 8.4.0 and < 8.11.1 occurs when an encrypted PDF is passed to an attachment processor through the REST API. The Elasticsearch ingest node that attempts to parse the PDF file will crash. This does not happen with password-protected PDF files or with unencrypted PDF files.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An uncaught exception in Elasticsearch >= 8.4.0 and < 8.11.1 occurs when an encrypted PDF is passed to an     attachment processor through the REST API. The Elasticsearch ingest node that attempts to parse the PDF     file will crash. This does not happen with password-protected PDF files or with unencrypted PDF files.
    (CVE-2024-23449)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - An uncaught exception in Elasticsearch >= 8.4.0 and < 8.11.1 occurs when an encrypted PDF is passed to an
    attachment processor through the REST API. The Elasticsearch ingest node that attempts to parse the PDF
    file will crash. This does not happen with password-protected PDF files or with unencrypted PDF files.
    (CVE-2024-23449)

The version of Elasticsearch installed on the remote host is between 8.4.0 and prior to 8.11.1. It is, therefore, affected by a denial of service (DoS) vulnerability, due to an uncaught exception that occurs when an encrypted PDF is passed to an attachment processor through the REST API. The Elasticsearch ingest node that attempts to parse the PDF file will crash. This does not happen with password-protected PDF files or with unencrypted PDF files.

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