Описание
Nokogiri is a Rubygem providing HTML, XML, SAX, and Reader parsers with XPath and CSS selector support. In Nokogiri v1.12.4 and earlier, on JRuby only, the SAX parser resolves external entities by default. Users of Nokogiri on JRuby who parse untrusted documents using any of these classes are affected: Nokogiri::XML::SAX::Parse, Nokogiri::HTML4::SAX::Parser or its alias Nokogiri::HTML::SAX::Parser, Nokogiri::XML::SAX::PushParser, and Nokogiri::HTML4::SAX::PushParser or its alias Nokogiri::HTML::SAX::PushParser. JRuby users should upgrade to Nokogiri v1.12.5 or later to receive a patch for this issue. There are no workarounds available for v1.12.4 or earlier. CRuby users are not affected.
A XML External Entity Reference (XXE) vulnerability was found in RubyGem Nokogiri on JRuby (Java implementation of the Ruby). If attacker is able to insert untrusted XML input containing a reference to an external entity, it is processed by a weakly configured SAX parser, resulting disclosure of confidential data and server side request forgery. The highest threat from this vulnerability is to system confidentiality.
