The remote host is running a version of macOS / Mac OS X that is 14.x prior to 14.8.2. It is, therefore, affected by multiple vulnerabilities:

  - There exists a vulnerability in SQLite versions before 3.50.2 where the number of aggregate terms could     exceed the number of columns available. This could lead to a memory corruption issue. We recommend     upgrading to version 3.50.2 or above. (CVE-2025-6965)

  - REXML is an XML toolkit for Ruby. The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML     that has many deep elements that have same local name attributes. If you need to parse untrusted XMLs with     tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other     parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected. The REXML     gem 3.3.6 or later include the patch to fix the vulnerability. (CVE-2024-43398)

  - REXML is an XML toolkit for Ruby. The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an     XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does     not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or     later include the patch to fix the vulnerability. (CVE-2024-49761)

  - A permissions issue was addressed with improved validation. This issue is fixed in iPadOS 17.7.6, macOS     Sequoia 15.4, macOS Sequoia 15.7.2, macOS Sonoma 14.7.5, macOS Sonoma 14.8.2, macOS Tahoe 26.1, macOS     Ventura 13.7.5. A shortcut may be able to access files that are normally inaccessible to the Shortcuts     app. (CVE-2025-30465)

  - A logging issue was addressed with improved data redaction. This issue is fixed in iOS 18.4 and iPadOS     18.4, macOS Sequoia 15.4, macOS Sonoma 14.8.2, visionOS 2.4. An app may be able to access sensitive user     data. (CVE-2025-31199)

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

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has a package installed that is affected by a vulnerability as referenced in the USN-7709-1 advisory.

    It was discovered that WEBrick incorrectly parsed HTTP headers. In configurations where WEBrick is placed     behind an HTTP proxy, a remote attacker could possibly use this issue to perform an HTTP Request Smuggling     attack.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

According to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    Ruby WEBrick read_header HTTP Request Smuggling Vulnerability. This vulnerability allows remote attackers     to smuggle arbitrary HTTP requests on affected installations of Ruby WEBrick. This issue is exploitable     when the product is deployed behind an HTTP proxy that fulfills specific conditions.

    The specific flaw exists within the read_headers method. The issue results from the inconsistent parsing     of terminators of HTTP headers. An attacker can leverage this vulnerability to smuggle arbitrary HTTP     requests. Was ZDI-CAN-21876.(CVE-2025-6442)

Tenable has extracted the preceding description block directly from the EulerOS ruby security advisory.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7840-1 advisory.

    It was discovered that the REXML module bunded into Ruby incorrectly handled parsing XML documents with     repeated instances of certain characters. An attacker could possibly use this issue to cause REXML to     consume excessive resources, leading to a denial of service. Ubuntu 18.04 LTS and Ubuntu 20.04 LTS were     previously addressed in USN-7256-1 and USN-7734-1. This update addresses the issue in Ubuntu 16.04 LTS.
