The version of ruby24 installed on the remote host is prior to 2.4.10-2.12. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1422 advisory.

    Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows HTTP Response Splitting. If a     program using WEBrick inserts untrusted input into the response header, an attacker can exploit it to     insert a newline character to split a header, and inject malicious content to deceive clients. NOTE: this     issue exists because of an incomplete fix forCVE-2017-17742, which addressed the CRLF vector, but did not     address an isolated CR or an isolated LF. (CVE-2019-16254)

    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)

    jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request     is performed without the dataType option, causing text/javascript responses to be executed.
    (CVE-2015-9251)

    The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through     2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar toCVE-2013-0269, but does not     rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead     to creation of a malicious object within the interpreter, with adverse effects that are application-     dependent. (CVE-2020-10663)

    jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function     does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery     determined whether the input was HTML by looking for the '<' character anywhere in the string, giving     attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery     only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability     only to attackers who can control the beginning of a string, which is far less common. (CVE-2012-6708)

    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)

    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. A flaw was discovered in Ruby in the way certain functions handled strings     containing NULL bytes. Specifically, the built-in methods File.fnmatch and its alias File.fnmatch? did not     properly handle path patterns containing the NULL byte. A remote attacker could exploit this flaw to make     a Ruby script access unexpected files and to bypass intended file system access restrictions.
    (CVE-2019-15845)

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

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