CVE:CVE-2012-5887
CNNVD:CNNVD-201211-315
Apache Apache Tomcat是美国阿帕奇（Apache）软件基金会下属的Jakarta项目的一款轻量级Web应用服务器，它主要用于开发和调试JSP程序，适用于中小型系统。
Apache Tomcat 5.5.36之前的5.5.x版本、6.0.36之前的6.x版本、7.0.30之前的7.x版本中的HTTP Digest Access Authentication实现中存在漏洞，该漏洞源于程序在连带执行凭证检查的同时未对过期的随机数值进行正确的检查。通过在网络中嗅探有效的请求，远程攻击者可利用该漏洞绕过预期的访问限制。
