appscan 安全漏洞修复

1.会话标识未更新：登录页面加入以下代码

Java代码







request.getSession(true).invalidate();//清空session

Cookie cookie = request.getCookies()[0];//获取cookie

cookie.setMaxAge(0);//让cookie过期

request.getSession(true).invalidate();//清空session
Cookie cookie = request.getCookies()[0];//获取cookie
cookie.setMaxAge(0);//让cookie过期

不是很明白session的机制，高手路过可以指教一下。

2.跨站点请求伪造：

在出错的url加参数sessionid。

Java代码







response.getWriter().write( "<script>parent.location.href='dbase/admin/loginJsp.action?sessionId="+sessionId+"'</script>");

response.getWriter().write(	"<script>parent.location.href='dbase/admin/loginJsp.action?sessionId="+sessionId+"'</script>");

如果带参数报ssl错误，使用下面的post方式传值：

Java代码







response.getWriter().write(

"<script language=\"javascript\"> " +

"document.write(\"<form action=dbase/admin/loginJsp.action method=post name=formx1 style='display:none'>\");" +

"document.write(\"<input type=hidden name=name value='"+sessionId+"'\");" +

"document.write(\"</form>\");" +

"document.formx1.submit();" +

"</script>"

);

response.getWriter().write(
"<script language=\"javascript\"> " +
"document.write(\"<form action=dbase/admin/loginJsp.action method=post name=formx1 style='display:none'>\");" +
"document.write(\"<input type=hidden name=name value='"+sessionId+"'\");" +
"document.write(\"</form>\");" +
"document.formx1.submit();" +
"</script>"
);

3.启用不安全HTTP方法

Java代码







修改web工程中或者服务器web.xml,增加安全配置信息，禁用不必要HTTP方法

<security-constraint>

<web-resource-collection>

<url-pattern>/*</url-pattern>

<http-method>PUT</http-method>

<http-method>DELETE</http-method>

<http-method>HEAD</http-method>

<http-method>OPTIONS</http-method>

<http-method>TRACE</http-method>

</web-resource-collection>

<auth-constraint>

</auth-constraint>

</security-constraint>

<login-config>

<auth-method>BASIC</auth-method>

</login-config>

修改web工程中或者服务器web.xml,增加安全配置信息，禁用不必要HTTP方法
<security-constraint>
<web-resource-collection>
<url-pattern>/*</url-pattern>
<http-method>PUT</http-method>
<http-method>DELETE</http-method>
<http-method>HEAD</http-method>
<http-method>OPTIONS</http-method>
<http-method>TRACE</http-method>
</web-resource-collection>
<auth-constraint>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
</login-config>

4.已解密登录请求

配置SSL，具体见http://serisboy.iteye.com/admin/blogs/1320231

在web.xml加入如下配置。

Java代码







<security-constraint>

<web-resource-collection >

<web-resource-name >SSL</web-resource-name>

<url-pattern>/*</url-pattern>

</web-resource-collection>

<user-data-constraint>

<transport-guarantee>CONFIDENTIAL</transportguarantee>

</user-data-constraint>

</security-constraint>

<security-constraint>
<web-resource-collection >
<web-resource-name >SSL</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transportguarantee>
</user-data-constraint>
</security-constraint>

5.高速缓存的ssl页面

Java代码







页面

<meta http-equiv="Pragma" contect="no-cache">

页面
<meta http-equiv="Pragma" contect="no-cache">

Java代码







java代码

response.setHeader("Pragma", "No-cache");

java代码
response.setHeader("Pragma", "No-cache");

6.目录列表

配置文件目标拒绝访问。

在conf/web.xml下:

Java代码







<servlet>

<servlet-name> default </servlet-name>

<servlet-class> org.apache.catalina.servlets.DefaultServlet </servlet-class>

<init-param>

<param-name> debug </param-name>

<param-value> 0 </param-value>

</init-param>

<init-param>

<param-name> listings </param-name>

<param-value> false </param-value>

</init-param>

<load-on-startup> 1 </load-on-startup>

</servlet>

<servlet>
<servlet-name> default </servlet-name>
<servlet-class> org.apache.catalina.servlets.DefaultServlet </servlet-class>
<init-param>
<param-name> debug </param-name>
<param-value> 0 </param-value>
</init-param>
<init-param>
<param-name> listings </param-name>
<param-value> false </param-value>
</init-param>
<load-on-startup> 1 </load-on-startup>
</servlet>

把listings对应的value设置为fasle.

或者把上面的这个servlet加到你的虚拟路径下的web-inf/web.xml 中,把

servlet-name改为其它的,再加一下servlet-mapping

Java代码







<servlet>

<servlet-name> default1 </servlet-name>

<servlet-class> org.apache.catalina.servlets.DefaultServlet </servlet-class>

<init-param>

<param-name> debug </param-name>

<param-value> 0 </param-value>

</init-param>

<init-param>

<param-name> listings </param-name>

<param-value> false </param-value>

</init-param>

<load-on-startup> 1 </load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name> default1 </servlet-name>

<url-pattern> / </url-pattern>

<servlet-mapping>

<servlet>
<servlet-name> default1 </servlet-name>
<servlet-class> org.apache.catalina.servlets.DefaultServlet </servlet-class>
<init-param>
<param-name> debug </param-name>
<param-value> 0 </param-value>
</init-param>
<init-param>
<param-name> listings </param-name>
<param-value> false </param-value>
</init-param>
<load-on-startup> 1 </load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name> default1 </servlet-name>
<url-pattern> / </url-pattern>
<servlet-mapping>
