书接上文，之前提到我们可以用java版的libinjection进行sql注入防护。
那么我今天花了一天的时间，在sqlmap的level=5 和 risk=3的情况下对拼接的sql进行安全测试，本文不涵盖tamper，否则本文的内容会异常复杂。
在试验过程中我发现，其实很多的报错情况，以及一些sql报错，可以看到一些 libinjection 没有对应防护策略的端倪。

1 解决txt记录写文件的大小限制问题
1.0.1 前言
公众号NOP Team曾经发布一个名为“远程下载的通用替代方案|红队攻防”，文章链接为
https://mp.weixin.qq.com/s/Z1zp7klk--uQ1OnzljNESw，这篇文章有个痛点就是不能写入
太大的文件，本次tip目的为解决这个痛点。
1.0.2 解决思路
由于留给TXT记录的长度最长差不多为65515左右的原因，导致通过单词txt记录写入大文件成
为不可能。
解决办法就是制造多个txt记录写入文件再进行转换。如此一来大文件就可以写入了。

Tomcat JMXProxy RCE
0x00 前言
在介绍该漏洞之前有必要先进行一些说明
（1）不影响默认配置的 Tomcat
（2）不影响 SpringBoot 只影响通过 war 部署的项目
（3）该漏洞为利用链中的一环，配合第三方平台未授权访问或弱口令可以直接利用
既然官方不认，那我直接公开了
