The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0543 advisory.

  • rubygem-bundler: Dependencies of gems with explicit source may be installed from a different source (CVE-2020-36327)

  • rubygem-rdoc: Command injection vulnerability in RDoc (CVE-2021-31799)

  • ruby: FTP PASV command response can cause Net::FTP to connect to arbitrary host (CVE-2021-31810)

  • ruby: StartTLS stripping vulnerability in Net::IMAP (CVE-2021-32066)

  • ruby: Regular expression denial of service vulnerability of Date parsing methods (CVE-2021-41817)

  • ruby: Cookie prefix spoofing in CGI::Cookie.parse (CVE-2021-41819)

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