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

  • Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within File.fnmatch functions.(CVE-2019-15845)

  • Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows code injection if the first argument (aka the ‘command’ argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An attacker can exploit this to call an arbitrary Ruby method.(CVE-2019-16255)

  • WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 has a regular expression Denial of Service cause by looping/backtracking. A victim must expose a WEBrick server that uses DigestAuth to the Internet or a untrusted network.(CVE-2019-16201)

  • The web application exposed by the Canon Oce Colorwave 500 4.0.0.0 printer is vulnerable to Stored XSS in /TemplateManager/indexExternalLocation.jsp. The vulnerable parameter is map(template_name). NOTE: this is fixed in the latest version.(CVE-2020-10667)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
