AusCERT Security Bulletin Summary
---------------------------------
Product: Intuit QuickBooks Online Edition 9 and prior
Publisher: US-CERT
Operating System: Windows
Impact: Execute Arbitrary Code/Commands
Access: Remote/Unauthenticated
CVE Names: CVE-2007-4471 CVE-2007-0322
Original Bulletin: http://www.kb.cert.org/vuls/id/907481
http://www.kb.cert.org/vuls/id/979638
Comment:
This bulletin contains two separate US-CERT advisories for
vulnerabilities in the QuickBooks Online ActiveX control.
Users who used the QuickBooks Online Edition website prior to
March 15 2007 may have this vulnerable control installed. If affected
users later visit a malicious web page using Internet Explorer, a
remote attacker may execute arbitrary code, compromising the computer.
According to Intuit, logging onto the QuickBooks Online website after
March 15 will update the software to version 10, which is not vulnerable.

US-CERT Vulnerability Note VU#907481
Intuit QuickBooks Online Edition ActiveX control stack buffer overflows
Overview
The Intuit QuickBooks Online Edition ActiveX control contains multiple
stack buffer overflows, which may allow a remote, unauthenticated
attacker to execute arbitrary code on a vulnerable system.
I. Description
Intuit QuickBooks Online Edition is a version of QuickBooks that
functions within Internet Explorer as an ActiveX control. This ActiveX
control contains multiple stack buffer overflow vulnerabilities, which
can allow an overwrite of the process Structured Exception Handler (SEH).
II. Impact
By convincing a user to view a specially crafted HTML document (e.g.,
a web page or an HTML email message or attachment), an attacker may
be able to execute arbitrary code with the privileges of the user.
The attacker could also cause Internet Explorer (or the program using
the WebBrowser control) to crash.
III. Solution
Apply an update
This issue is addressed in version 10 of the QuickBooks Online Edition
ActiveX control. The fixed version of the QuickBooks Online Edition
ActiveX control can be installed from the QuickBooks Online Edition
web site.
Disable the QuickBooks Online Edition ActiveX control in Internet Explorer
The vulnerable QuickBooks Online Edition ActiveX controls (versions
9 and earlier) can be disabled in Internet Explorer by setting the
kill bit for the following CLSIDs:
{CF9DEB90-8DE3-11D5-BAE4-00105AAAFF94}
{4F720B9C-24B1-4948-A035-8853DC01F19E}

{40F8967E-34A6-474a-837A-CEC1E7DAC54C}
More information about how to set the kill bit is available in Microsoft
Support Document 240797. Alternatively, the following text can be
saved as a .REG file and imported to set the kill bit for this control:

an attacker) appears to prevent exploitation of this and other ActiveX
vulnerabilities. Instructions for disabling ActiveX in the Internet

US-CERT Vulnerability Note VU#979638
Intuit QuickBooks Online Edition ActiveX control fails to properly
restrict access to methods
Overview
The Intuit QuickBooks Online Edition ActiveX control fails to properly
restrict access to dangerous methods, which could allow a remote
attacker to execute arbitrary code on a vulnerable system.
I. Description
Intuit QuickBooks Online Edition is a version of QuickBooks that is
implemented as an ActiveX control. This ActiveX control contains
several dangerous methods, such as httpGETToFile() and
httpPOSTFromFile(). These methods can be used to download or upload
files in arbitrary locations.
II. Impact
By convincing a victim to view an HTML document (web page, HTML email,
or email attachment), an attacker could download arbitrary files to
a vulnerable system within the security context of the user running
IE. These files could contain code that could be executed through
other means. The user may click the file inadvertently, or the file
may be placed in a sensitive location, such as the Windows Startup
folder where it will automatically execute the next time the user
logs onto the system. An attacker can also retrieve arbitrary files
from a victim's computer.
III. Solution
Apply an update
This issue is addressed in version 10 of the QuickBooks Online Edition
ActiveX control. The fixed version of the QuickBooks Online Edition
ActiveX control can be installed from the QuickBooks Online Edition
web site.
Disable the QuickBooks Online Edition ActiveX control in Internet Explorer
The vulnerable QuickBooks Online Edition ActiveX controls (versions
9 and earlier) can be disabled in Internet Explorer by setting the
kill bit for the following CLSIDs:
