[原文]Apache Tomcat 4.0.3, and possibly other versions before 4.1.3 beta, allows remote attackers to cause a denial of service (resource exhaustion) via a large number of requests to the server with null characters, which causes the working threads to hang.


[CNNVD]Apache Tomcat NULL字符畸形请求远程拒绝服务攻击漏洞(CNNVD-200210-159)

        
        Apache Tomcat是一款由Apache Foundation维护的免费开放源代码的Web服务器程序。
        Apache Tomcat在处理包含NULL字符的特殊请求时存在漏洞,远程攻击者可以利用此漏洞进行拒绝服务攻击。
        攻击者可以通过提交包含大量NULL字符的请求给Apache Tomcat服务程序,可使服务器程序的线程崩溃,默认安装启动75个工作线程,意味发送类似请求75次可以导致Apache Tomcat服务程序停止响应。
