CyberRota Analysis
AI-GeneratedApache's StaxUtils is vulnerable to denial of service due to the absence of default limits on the number of elements and characters in XML documents, which can lead to excessive memory and CPU usage during parsing. This vulnerability primarily affects applications utilizing CXF for XML processing, particularly those that do not have request size limits configured. Organizations using affected versions should prioritize upgrading to versions 4.2.4, 4.1.9, or 3.6.13 to mitigate this risk.
Original NVD Description
By default, StaxUtils placed no limit on the total number of elements or the total number of characters in an XML document. A very large request could therefore use a lot of memory and CPU during parsing, especially where CXF builds a DOM from the input (for example SAAJ or WS-Security), and could cause a denial of service when no request size limit was configured. Both limits now have defaults: the maximum element count is 100 × maxChildElements (5,000,000 by default), and the maximum document size is 256M characters. Applications that process larger documents can raise the limits with the org.apache.cxf.stax.maxElementCount and org.apache.cxf.stax.maxXMLCharacters properties. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
