fmms 12年前
CVE-2011-1184 Apache Tomcat - Multiple weaknesses in HTTP DIGEST authentication <br /> <br /> 严重性: 中等 <br /> <br /> 所影响的版本： <br /> - - Tomcat 7.0.0 to 7.0.11 <br /> - - Tomcat 6.0.0 to 6.0.32 <br /> - - Tomcat 5.5.0 to 5.5.33 <br /> - - Earlier, unsupported versions may also be affected <br /> <br /> 漏洞描述: <br /> The implementation of HTTP DIGEST authentication was discovered to <br /> have several weaknesses: <br /> - - replay attacks were permitted <br /> - - server nonces were not checked <br /> - - client nonce counts were not checked <br /> - - qop values were not checked <br /> - - realm values were not checked <br /> - - the server secret was hard-coded to a known string <br /> The result of these weaknesses is that DIGEST authentication was only <br /> as secure as BASIC authentication. <br /> <br /> 解决方法: <br /> Users of Tomcat 7.0.x should upgrade to 7.0.12 or later <br /> Users of Tomcat 6.0.x should upgrade to 6.0.33 or later <br /> Users of Tomcat 5.5.x should upgrade to 5.5.34 or later <div id="p_fullcontent" class="detail"> <p><strong><img title="Tomcat" border="0" alt="Tomcat" src="http://tomcat.apache.org/images/tomcat.gif" /><br /> Tomcat</strong> 服务器是一个免费的开放源代码的Web 应用服务器。</p> <p>Tomcat是Apache 软件基金会（Apache Software Foundation）的Jakarta 项目中的一个核心项目，由Apache、Sun 和其他一些公司及个人共同开发而成。由于有了Sun 的参与和支持，最新的Servlet 和JSP 规范总是能在Tomcat 中得到体现，Tomcat 5 支持最新的Servlet 2.4 和JSP 2.0 规范。因为Tomcat 技术先进、性能稳定，而且免费，因而深受Java 爱好者的喜爱并得到了部分软件开发商的认可，成为目前比较流行的Web 应用服务器。</p> <p>Tomcat 很受广大程序员的喜欢，因为它运行时占用的系统资源小，扩展性好，支持负载平衡与邮件服务等开发应用系统常用的功能；而且它还在不断的改进和完善中，任何一个感兴趣的程序员都可以更改它或在其中加入新的功能。<br /> <br /> Tomcat 是一个小型的轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP 程序的首选。对于一个初学者来说，可以这样认为，当在一台机器上配置好Apache 服务器，可利用它响应对HTML 页面的访问请求。实际上Tomcat 部分是Apache 服务器的扩展，但它是独立运行的，所以当你运行tomcat 时，它实际上作为一个与Apache 独立的进程单独运行的。</p> <p>这里的诀窍是，当配置正确时，Apache 为HTML页面服务，而Tomcat 实际上运行JSP 页面和Servlet。另外，Tomcat和IIS、Apache等Web服务器一样，具有处理HTML页面的功能，另外它还是一个Servlet和 JSP容器，独立的Servlet容器是Tomcat的默认模式。不过，Tomcat处理静态HTML的能力不如Apache服务器。<span style="font-family:arial,helvetica,sanserif;color:#ffffff;"> <a name="7.0.21"><strong>7.0.21</strong> </a></span></p> <p></p> <p><a name="7.0.21"><span style="font-weight:bold;">最新版7.0.21下载</span><br /> Please</a> see the <a href="/misc/goto?guid=4958191682531667467" rel="nofollow">README</a> file for packaging information.
