BakBone NetVault Remote Heap Buffer Overflow (clientname)
------------------------------------------------------------------------
SUMMARY
<http://www.bakbone.com/> NetVault is "a professional backup and restore
solution for individual Windows and Linux servers and very small
heterogeneous UNIX, Windows NT/2000, Linux and Netware environments".
By crafting a special packet, a NetVault user can trigger a heap based
buffer overflow and run arbitrary code on the target machine.
DETAILS
Vulnerable Systems:
* NetVault 7.x, 6.x
While having a look at the communication protocol used by the NetVault's
client/server, the hat-squad has discovered several obscure points, as the
possibility to guess the computername, to notice several bytes in the
buffer referring to a string size stored in the heap. While playing with
such data, a malicious user can add his own server entry to the "Available
NetVault Machines" list nor at best for him, to override the heap where is
stored the submitted "clientname" and to finally control two pointers in
the heap management structure. Once freed or allocated; the heap is moving
one pointer into the second and the second into the first.
77F37111 8901 MOV DWORD PTR DS:[ECX], EAX
77F37113 8948 04 MOV DWORD PTR DS:[EAX+4], ECX
Needless to say that owning both pointers, the attacker is able to
overwrite any windows function marked as writable with any 32 bits value
we want. To HeapAllocate at around 33000 bytes will produce an access
violation.
