CyberRota Analysis
AI-GeneratedThe XML Injection vulnerability in the XmlBuilder module allows attackers to exploit the CDATA section handling, enabling content spoofing and arbitrary XML injection. This can lead to unauthorized manipulation of XML documents, potentially compromising data integrity for applications relying on this library. Developers and organizations using xml_builder versions from 0.0.7 to prior to 2.4.1 should prioritize patching this vulnerability to mitigate risks associated with untrusted input.

Original NVD Description
XML Injection vulnerability in joshnuss xml_builder (XmlBuilder module) allows Content Spoofing, XML Injection. This vulnerability is associated with program files lib/xml_builder.ex and program routines XmlBuilder.generate/1, XmlBuilder.generate/2, XmlBuilder.escape/1. The escape/1 clause for {:cdata, data} in lib/xml_builder.ex concatenates data verbatim between the CDATA opener <![CDATA[ and closer ]]> without rewriting or splitting on the embedded ]]> sequence. Because CDATA sections have no internal escape mechanism, the only safe way to embed arbitrary bytes is to split on ]]> and emit adjacent CDATA sections. An attacker who can supply input containing ]]> closes the CDATA section early; any bytes that follow are parsed as ordinary XML markup by downstream consumers, allowing injection of arbitrary elements, text, or entity references into the output document. This issue affects xml_builder: from 0.0.7 before 2.4.1.
