The version of ruby installed on the remote host is prior to 2.0.0.648-36. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2486 advisory.

  - 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)

  - 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 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 for CVE-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)

  - CGI::Cookie.parse in Ruby through 2.6.8 mishandles security prefixes in cookie names. This also affects     the CGI gem through 0.3.0 for Ruby. (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.
