CVE-2012-6685
First published: Mon Jan 05 2015(Updated: )
An XML eXternal Entity (XXE) flaw was found in Nokogiri, a Ruby gem for parsing HTML, XML, and SAX. Using external XML entities, a remote attacker could specify a URL in a specially crafted XML that, when parsed, would cause a connection to that URL to be opened. A patch shipped with the 1.5.4 release of Nokogiri provided a "nonet" option to disable external connections. However, local file URLs could still be used to exploit this flaw. The 1.6.4 release of Nokogiri fixed this issue by using libxml2 2.9.0.
