Tomcat：在日志中获取'字符解码失败';可能的恶意攻击？

我刚刚有一个Tomcat实例停止响应（在杀死并重新启动后它开始正常工作），并且在它停止响应之前，它看起来像是在某个日志消息中，有人用无效请求发送垃圾邮件。以下是日志文件的摘录：Tomcat：在日志中获取'字符解码失败';可能的恶意攻击？

在日志中有相当多的内容。有没有人看过类似的东西？这是恶意攻击，还是Tomcat实例只是翻转/发疯？

更实际的是，有什么我可以做的，例如在Valve或Filter，检测这些请求并暂时禁止发起IP地址？我认为，因为Tomcat无法解码乱码参数，因此我不能只查找不符合参数的名称，并且如果找到它，就拒绝该请求。

编辑

同样的问题再次发生，这次我拍摄的线程转储。这是相当长（时间太长的全部包括，在事实）：

关闭我的头顶，它看起来像有等待HTTP守护线程的数目异常。

您运行的是哪个Tomcat版本？如果再次发生这种情况，你可以采取线程转储吗？你配置了多个连接器吗？如果是这样，你可以尝试*两个*连接器，看看他们是否回应，如果这再次发生？ – 2012-08-08 02:34:36

运行Tomcat 6.我认为确切的版本是6.0.26。应该只有一个连接器正在运行（服务器设置是或多或少的库存，除了端口设置为80）。我使用Cargo Maven2插件来实际启动Tomcat并部署我的web应用程序，如果这有所帮助。 – aroth 2012-08-08 04:08:22

FYI Tomcat默认启用8009上的AJP连接器。 – 2012-08-08 18:31:53

请尝试以下步骤;

编辑conf/server.xml并找到定义标记HTTP连接器的行。它会是这个样子，可能有多个参数：

<Connector port="8080"/>

添加的URIEncoding = “UTF-8” 属性到连接器：

<Connector port="8080" URIEncoding="UTF-8"/>

重新启动Tomcat

谢谢，我会试试看。就我而言，由于我使用Cargo和Maven2来启动服务器，因此通过在我的''pom.xml''中添加' UTF-8'来配置此设置。文件。 – aroth 2012-08-08 04:50:46

很好的时机，在重新启动服务器后不久，它又受到了另一轮请求的打击。不幸的是即使使用这个设置，它也会抱怨：'字符解码失败。参数''''''']'3'Sù'©Ð6nX\±6 $ 8a <èè％tõü³VÆ»Hÿëe2Y«t，Ñ'值''已被忽略。 – aroth 2012-08-08 04:57:42

@aroth删除 javax。埃尔 EL-API XXX 在你的pom.xml – 2012-08-08 05:10:41

你可以尝试使用javascript函数escape(parameter)，然后再发送请求。我希望我的回答不是很晚，对某人有用。
