Subject: [Full-Disclosure] VERITAS Backup Exec 8.x/9.x Remote UniversalExploit
Because k-otik are poor looser not respecting the publication of metasploit 2.3 , im forced to post my code.
/*
VERITAS Backup Exec v9.1.4691.SP1
v9.1.4691.SP0
v8.5.3572
Agent Browser Service, Remote Stack Overflow
Highly Critical
All credits to:
-iDEFENSE(discovery-www.iDEFENSE.com),
-Thor Doomen(iat-syscall[at]inbox.lv),
-H.D. Moore(scode-www.metasploit.com),
-Matt Miller(scode-www.hick.org)
ExtraNotes:
All my tests/debugs where a bit long (some days) firstly due to the big size
of Backup Exec and the unstability accross differents windows versions
to make working that IAT method with 100% success and the difficulty to debug it.
(As a recall, due to the 60 bytes only free, a tiny shellcode is send in first to scan
the recv function of benetns.exe and jump to the data submitted during the second send,
thanx syscall. Let's think large now. Imagine that you exploits the hole and you submit
the shellcode 5 minutes later, the service will hang on to death of course until a kill,
now imagine that you exploits the hole and you submit the shellcode too faslty for the,
computer processing, the shellcode can be missed, wont be executed again, sometimes yes/no, but really unstable.
Hopefully (or unfortunely for you admin :>) I'm here to optimize it and make it 100% working, universal,
stable whatever you want for the good fortune of script kiddies and to show what mean working to my good
friends ka-odick :>

= Universal
v0.1:
C code based on Thor Doomen's code posted at the metasploit mailing list,
excellent in the method, but super unstable to not say not working when used,
made some changes.
v0.2:
fix of the first big problem , the missed shellcode accross differents windows,
fixed by flooding benetns with more sends, timer really small, this is important.
padding 1 nop to the reverse shellcode as needed, else crash on reverse.
v0.3:
universal esi call across v9.1 SP0 and SP1, for the good fortune of script kiddies.
v0.4:
As a warning, this poc v0.4 as been tested working by an anonymous tester (never mentionned there)
on some organisations such nasa, states/edus, it's urgent to update 1 month after the advisory, sleepers.
Tips: -make sure that your ip is safe of null bytes in reverse mode.
-make sure that you targets the good version of Backup Exec,
else you crash it.
-Backup Exec v10.0 is now available, get it at www.veritas.com.
-Visit dfind.kd-team.com for a patched benetns.exe, quick solution
for an urgent update. (extracted from the hotfix at www.veritas.com)
Backup Exec 9.x is tested safe after replacing the .exe
