Re: [IMail Forum] SMTP Exploit Scanning Going on NOW

The fact that it crashes means that it could be exploited if someone gets a copy of 8.12 and determines offsets for your OS and Imail.  In the meantime, also try banning e-mail from the user [EMAIL PROTECTED] [ this might cause it to drop the connection before looking at the exploit.  Of course they can also have the FROM user to be anything in the future] .   ----- Original Message ----- From: Eddie Pang To: Imail_Forum@list.ipswitch.com Sent: Sunday, October 29, 2006 8:11 AM Subject: RE: [IMail Forum] SMTP Exploit Scanning Going on NOW Hi All,   Sorry I am running V8.12 and not 8.15 as previously reported.    I have compiled the exploit, and ran it against my server.  With version 8.12, I am not getting any of the injections as described (share, new user, port 4444 bind) .  However, after running the exploit all smtp will not respond to any connection request. You will have to manually stop/start SMTP to regain full function once again.   Here is the catch22.  You will need to enable Monitor Services if you wish to have SMTP auto restart should it hang.  This service in the past has created a bunch of networking issues for a few users..   Also, I am not seeing the same info as http://www.mail-archive.com/imail_forum%40list.ipswitch.com/msg108489.html .   My log looks like 10:29 02:43 SMTPD(a1dc000b002a1d33) [xxx.xxx.xxx.xxx] EHLO 10:29 02:43 SMTPD(a1dc000b002a1d33) [xxx.xxx.xxx.xxx] MAIL FROM <[EMAIL PROTECTED]> 10:29 02:43 SMTPD(a1dc000b002a1d33) [xxx.xxx.xxx.xxx] RCPT TO: <@qo: 10:29 02:44 SMTPD(0000000000000000) server starting on port 25 of student.chaminade.edu <<< AUTO RESTART OF SMTP via Monitor after SMTP fails to respond..   Display of Options from executable. ================================================= IMail 2006 and 8.x SMTP 'RCPT TO:' Stack Overflow Exploit Coded by Greg Linares < glinares.code  [at] GMAIL [dot] com > Usage: imailexploit [hostname] [port] <Payload> <JMP> Default port is 25   ============================== Payload Options: 1 = Default ============================== 1 = Share C:\ as 'Export' Share 2 = Add User 'Error' with Password 'Error' 3 = Win32 Bind CMD to Port 4444 4 = Change Administrator Password to '[EMAIL PROTECTED]' ============================== JMP Options: 1 = Default ============================== 1 = IMAIL 8.x SMTPDLL.DLL    [pop ebp, ret] 0x10036f71 2 = Win2003 SP1 English NTDLL.DLL [pop ebp, ret] 0x7c87d8af 3 = Win2003 SP0 English USER32.DLL [pop ebp, ret] 0x77d02289 4 = WinXP SP2 English NTDLL.DLL [pop ebp, ret] 0x7c967e23 5 = WinXP SP1 - SP0 English USER32.DLL [pop ebp, ret] 0x71ab389c 6 = Win2000 Universal English USER32.DLL [pop ebp, ret] 0x75021397 7 = Win2000 Universal French USER32.DLL [pop ebp, ret] 0x74fa1397 8 = Windows XP SP1 - SP2 German USER32.DLL [pop ebp, ret] 0x77d18c14     Hope this provides some info, atleast to users of Version 8.12.   Eddie :)
