  1. Vulnerability Overview

Recently, by using the Attack Trend Monitoring system (ATM), the NSFOCUS security team has discovered an Apache Axis remote command execution vulnerability, which allows attackers to obtain privileges of the target server and remotely execute commands without authorization by sending a crafted HTTP-POST request.

Apache Axis is an open-source XML-based web service framework. It consists of a Java and a C++ implementation of the SOAP server, and various utilities and APIs for generating and deploying web service applications. Using Apache Axis, developers can create interoperable and distributed computing applications.
