"The remote NewStart CGSL host, running version MAIN 7.02, has ruby packages installed that are affected by multiple
vulnerabilities:

  - A ReDoS issue was discovered in the URI component before 0.12.2 for Ruby. The URI parser mishandles
    invalid URLs that have specific characters. There is an increase in execution time for parsing strings to
    URI objects with rfc2396_parser.rb and rfc3986_parser.rb. NOTE: this issue exists becuse of an incomplete
    fix for CVE-2023-28755. Version 0.10.3 is also a fixed version. (CVE-2023-36617)

  - An issue was discovered in RDoc 6.3.3 through 6.6.2, as distributed in Ruby 3.x through 3.3.0. When
    parsing .rdoc_options (used for configuration in RDoc) as a YAML file, object injection and resultant
    remote code execution are possible because there are no restrictions on the classes that can be restored.
    (When loading the documentation cache, object injection and resultant remote code execution are also
    possible if there were a crafted cache.) The main fixed version is 6.6.3.1. For Ruby 3.0 users, a fixed
    version is rdoc 6.3.4.1. For Ruby 3.1 users, a fixed version is rdoc 6.4.1.1. For Ruby 3.2 users, a fixed
    version is rdoc 6.5.1.1. (CVE-2024-27281)

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