Bundler 1.16.0 through 2.2.9 and 2.2.11 through 2.2.16 sometimes chooses a dependency source based on the highest gem version number, which means that a rogue gem found at a public source may be chosen, even if the intended choice was a private gem that is a dependency of another private gem that is explicitly depended on by the application. NOTE: it is not correct to use CVE-2021-24105 for every "Dependency Confusion" issue in every product.

The remote host is affected by the vulnerability described in GLSA-202408-22 (Bundler: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Bundler. Please review the CVE identifiers referenced     below for details.

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

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

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ruby-3.0.2-155.el9 build changelog.

  - Bundler 1.16.0 through 2.2.9 and 2.2.11 through 2.2.16 sometimes chooses a dependency source based on the     highest gem version number, which means that a rogue gem found at a public source may be chosen, even if     the intended choice was a private gem that is a dependency of another private gem that is explicitly     depended on by the application. NOTE: it is not correct to use CVE-2021-24105 for every Dependency     Confusion issue in every product. (CVE-2020-36327)

  - In RDoc 3.11 through 6.x before 6.3.1, as distributed with Ruby through 3.0.1, it is possible to execute     arbitrary code via | and tags in a filename. (CVE-2021-31799)

  - An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. A malicious FTP     server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port.
    This potentially makes curl extract information about services that are otherwise private and not     disclosed (e.g., the attacker can conduct port scans and service banner extractions). (CVE-2021-31810)

  - An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does     not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-     middle attackers to bypass the TLS protections by leveraging a network position between the client and the     registry to block the StartTLS command, aka a StartTLS stripping attack. (CVE-2021-32066)

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