CVE:CVE-2012-5885
CNNVD:CNNVD-201211-313
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实现中的replay-countermeasure功能中存在漏洞，该漏洞源于程序追踪cnonce(又名客户端随机数)值而不是追踪nonce(又名服务器端随机数)和nc(又名随机数计数)值。远程攻击者利用该漏洞通过在网络中嗅探有效的请求，绕过预期的访问限制。
solution:Upgrade apache tomcat to a higher version than 5.5.0,5.5.1,5.5.2,5.5.3,5.5.4,5.5.5,5.5.6,5.5.7,5.5.8,5.5.9,5.5.10,5.5.11,5.5.12,5.5.13,5.5.14,5.5.15,5.5.16,5.5.17,5.5.18,5.5.19,5.5.20,5.5.21,5.5.22,5.5.23,5.5.24,5.5.25,5.5.26,5.5.27,5.5.28,5.5.29,5.5.30,5.5.31,5.5.32,5.5.33,5.5.34,5.5.35,6.0,6.0.0,6.0.0:alpha,6.0.1,6.0.1:alpha,6.0.2,6.0.2:alpha,6.0.2:beta,6.0.3,6.0.4,6.0.4:alpha,6.0.5,6.0.6,6.0.6:alpha,6.0.7,6.0.7:alpha,6.0.7:beta,6.0.8,6.0.8:alpha,6.0.9,6.0.9:beta,6.0.10,6.0.11,6.0.12,6.0.13,6.0.14,6.0.15,6.0.16,6.0.17,6.0.18,6.0.19,6.0.20,6.0.24,6.0.26,6.0.27,6.0.28,6.0.29,6.0.30,6.0.31,6.0.32,6.0.33,6.0.35,7.0.0,7.0.0:beta,7.0.1,7.0.2,7.0.2:beta,7.0.3,7.0.4,7.0.4:beta,7.0.5,7.0.6,7.0.7,7.0.8,7.0.9,7.0.10,7.0.11,7.0.12,7.0.13,7.0.14,7.0.15,7.0.16,7.0.17,7.0.18,7.0.19,7.0.20,7.0.21,7.0.22,7.0.23,7.0.25,7.0.28,and avoid the version 5.5.0,5.5.1,5.5.2,5.5.3,5.5.4,5.5.5,5.5.6,5.5.7,5.5.8,5.5.9,5.5.10,5.5.11,5.5.12,5.5.13,5.5.14,5.5.15,5.5.16,5.5.17,5.5.18,5.5.19,5.5.20,5.5.21,5.5.22,5.5.23,5.5.24,5.5.25,5.5.26,5.5.27,5.5.28,5.5.29,5.5.30,5.5.31,5.5.32,5.5.33,5.5.34,5.5.35,6.0,6.0.0,6.0.0:alpha,6.0.1,6.0.1:alpha,6.0.2,6.0.2:alpha,6.0.2:beta,6.0.3,6.0.4,6.0.4:alpha,6.0.5,6.0.6,6.0.6:alpha,6.0.7,6.0.7:alpha,6.0.7:beta,6.0.8,6.0.8:alpha,6.0.9,6.0.9:beta,6.0.10,6.0.11,6.0.12,6.0.13,6.0.14,6.0.15,6.0.16,6.0.17,6.0.18,6.0.19,6.0.20,6.0.24,6.0.26,6.0.27,6.0.28,6.0.29,6.0.30,6.0.31,6.0.32,6.0.33,6.0.35,7.0.0,7.0.0:beta,7.0.1,7.0.2,7.0.2:beta,7.0.3,7.0.4,7.0.4:beta,7.0.5,7.0.6,7.0.7,7.0.8,7.0.9,7.0.10,7.0.11,7.0.12,7.0.13,7.0.14,7.0.15,7.0.16,7.0.17,7.0.18,7.0.19,7.0.20,7.0.21,7.0.22,7.0.23,7.0.25,7.0.28
