iDEFENSE Security Advisory 08.03.04: NGSEC StackDefender 1.10 vulnerable to remote/local Denial of Service which may crash the underlying system.

NGSEC StackDefender 1.10 Invalid Pointer Dereference Vulnerability 

iDEFENSE Security Advisory 08.03.04:


I. BACKGROUND

StackDefender is an IPS (Intrusion Prevention System), for Win32
platforms, that will deny shellcode from executing in User Stack and
Writable memory regions. StackDefender uses PAX technology for this
purpose.

II. DESCRIPTION

StackDefender offers protection by forcing executables run on a
protected system to load StackDefender dll's. This is done by hooking
the ZwOpenFile and ZwCreateFile functions. These two kernel API's are
responsible opening and creating files. The ZwOpenFile and ZwCreateFile
function declarations are as follows:

NTSTATUS  ZwCreateFile(OUT PHANDLE  FileHandle, IN ACCESS_MASK  DesiredAccess, IN POBJECT_ATTRIBUTES  ObjectAttributes, OUT PIO_STATUS_BLOCK  IoStatusBlock, IN PLARGE_INTEGER  AllocationSize  OPTIONAL, IN ULONG  FileAttributes, IN ULONG  ShareAccess, IN ULONG  CreateDisposition, IN ULONG  CreateOptions, IN PVOID  EaBuffer  OPTIONAL, IN ULONG  EaLength);
NTSTATUS  ZwOpenFile(OUT PHANDLE  FileHandle, IN ACCESS_MASK  DesiredAccess, IN POBJECT_ATTRIBUTES  ObjectAttributes, OUT PIO_STATUS_BLOCK  IoStatusBlock, IN ULONG  ShareAccess, IN ULONG  OpenOptions);
The problem specifically exists because StackDefender fails to verify
'ObjectAttribues' as a valid address prior accessing the structures
members.

III. ANALYSIS

Successful exploitation allows remote and local attackers to cause the
underlying system to crash. This is possible by specifying an invalid
address for 'ObjectAttribues'. Exploitation requires that an attacker
has an exploitation vector to the system that StackDefender attempts to
block.

IV. DETECTION

iDEFENSE has confirmed the existence of this vulnerability in
StackDefender 1.10.

V. WORKAROUND

iDEFENSE is currently unaware of any workarounds for this issue.

VI. VENDOR RESPONSE

The vendor has discontinued support for StackDefender 1.10 and has
recommended that all users still using StackDefender 1.10 upgrade to
StackDefender 2.10.

http://www.ngsec.com/downloads/stackdefender/StackDefender-2.10.exe

VII. CVE INFORMATION

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CAN-2004-0767 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org), which standardizes names for
security problems.

- 漏洞讨论

StackDefender is prone to a vulnerability that may permit attackers to crash the computer. This issue may be triggered if the program attempts to dereference an invalid pointer.

To exploit this issue, the attacker must be able to cause memory corruption on the host computer, such as through exploitation of buffer overflow in another application. This will force the software to attempt to block attempts to exploit the memory corruption vulnerability and in turn expose this vulnerability.

This issue is known to affect StackDefender 2.0.
