Background
Apache CXF is an open-source web services framework that provides a comprehensive set of tools and libraries for developing SOAP and RESTful web services. It is widely used in Java-based applications to facilitate communication between different systems. The vulnerability identified as CVE-2014-0109 affects versions of Apache CXF before 2.6.14 and 2.7.x before 2.7.11. This vulnerability allows remote attackers to cause a denial of service (memory consumption) by sending a large request with the Content-Type set to text/html to a SOAP endpoint, triggering an error.
Vulnerability Detail
The vulnerability in Apache CXF arises from the lack of proper input validation and resource management. When a SOAP endpoint receives a large request with the Content-Type set to text/html, the framework fails to handle it correctly, leading to uncontrolled resource consumption. This can result in a denial of service condition where the system becomes unresponsive or crashes due to excessive memory usage. Attackers can exploit this vulnerability remotely, potentially disrupting the availability of the affected service.
How To Fix
