**********************************************************************
It's been a bumper month for Microsoft security bulletins
(hence the delay in this month's Digest) with the release
of no fewer than 13 bulletins in the past six weeks - and
that does not include the re-release of some bulletins due
to updates or changes. According to Government Computer News
(http://www.gcn.com/vol1_no1/daily-updates/17874-1.html), Microsoft
halted all new software development for a month to debug existing code.
Is the flurry of security bulletins the result of some much-needed
repair work? We'd like to think so...but reading the fine print
of many of this month's bulletins shows Microsoft crediting outside
sources such as eEye Digital Security, Bindview RAZOR, HD Moore, and
others for bringing the flaws to Redmond's attention. Perhaps we'll
see the results of Microsoft's "spring cleaning" in the next Security
Rollup.
As always, please send comments and feedback to windows
sans.org.

Section II: Security Alert Summary
3. Microsoft Security Bulletins
3.1 MS02-005: 11 February 2002 Cumulative Patch for Internet Explorer
- released 11 February 2002
Risk: **CRITICAL
- Internet systems: CRITICAL
- Intranet systems: CRITICAL
- Client systems: CRITICAL
Impact: various, including run code of attacker's choice
Systems Affected:
- Internet Explorer 6.0
- Internet Explorer 5.5
- Internet Explorer 5.01
- Earlier versions are no longer supported, were not tested, and
may or may not be vulnerable.
Summary:
This bulletin and its associated patch are intended to address all
known vulnerabilities to date with Internet Explorer 5.01, 5.5, and
6.0. This includes six newly discovered vulnerabilities (including a
buffer overflow) in addition to previously disclosed vulnerabilities.
The newly discovered issues are:
1. Buffer overflow. HTML includes an <EMBED> tag that allows a
document to be incorporated into a web page. The SRC information
in the <EMBED> tag gives the location of the content to be embedded.
A flaw in the way IE parses the SRC information makes it possible for
an attacker to craft a specially formatted SRC string that allows him
to run arbitrary code on the user's system. The code would execute
with the privileges of the Internet Explorer application (i.e.,
the user). The attack would NOT work if the "Run ActiveX Controls
and Plugins" security option were disabled for the security zone in
which the page was opened (this option is disabled by default only
in the Restricted Sites Zone). For email-based HTML attacks, Outlook
2002 and Outlook Express 6 open mail in the Restricted Sites Zone by
default. Outlook 98 and Outlook 2000 with the Email Security Update
patch applied also open mail in the Restricted Sites Zone by default.
IE 5.01 is not affected by this vulnerability.
2. File reading via GetObject. This vulnerability was reported in
last month's Windows Digest (Volume 5, number 2, item 4.1.1). A flaw
in the Jscript GetObject() function, when combined with the ActiveX
object 'htmlfile', could be used to allow an attacker to create a
malicious web page or HTML email that could read any file on the
user's hard drive, if the file location was known. The flaw could
be exploited via a specially crafted script placed on a web site.
The attack is blocked if Active Scripting is disabled, which is the
default in the Restricted Sites Zone.
3. File download spoofing. An error in the way IE handles the
Content-Type and Content-Disposition fields allows an attacker to
misrepresent the name of a file that a user was downloaded through IE.
This could be used to trick a user into downloading what he thought
was a "safe" file type but that was actually dangerous.
4. Application invocation. A flaw in the way IE handles the
Content-Type field allows an attacker to specify the application
that should be used to open a file on a web site. IE should only use
registered, safe applications to open files (i.e., using Word for a
.doc file), but an attacker can bypass those restrictions. Depending
on the file being downloaded and the applications available on the
system, the attacker could take various actions such as modifying or
deleting data on the hard drive.
5. Script execution. When IE loads a web page, it performs security
checks such as determining whether a page contains scripts, and
whether or not the scripts should be allowed to execute based on
the user's security settings. Certain HTML tags can allow objects
such as scripts to be triggered after the page is initially loaded.
Because the script is not present during the initial security check
and IE performs no further checks, the script could execute even if
the user had disabled scripting. IE 5.01 is not affected by this
vulnerability.
6. Frame domain verification. This is a variant of an issue originally
discussed in MS01-058. An attacker could create a malicious web page
that opens two browser windows, one to the web server's domain and one
to the user's local system. The Document.open function can then be
used to pass information from the local window to the domain window,
allowing the attacker to read any file on the local system whose name
and location were known. IE 5.01 is not affected by this vulnerability.

- released 21 February 2002
- updated patch information 27 February 2002
- updated patch information 5 March 2002
- updated patch information 11 March 2002
Risk: ****CRITICAL
- Internet systems: MODERATE
- Intranet systems: MODERATE
- Client systems: CRITICAL
Impact: information disclosure
Systems Affected:
- Systems using Microsoft XML Core Services v2.6, 3.0 and 4.0,
which include:
* Windows XP
* Internet Explorer 6.0
* SQL Server 2000
Summary:
Microsoft XML Core Services provide functions for working with XML
documents. This includes the XMLHTTP ActiveX control that uses HTTP
to transfer XML documents over the Internet. Because XMLHTTP does
not correctly obey the restrictions of the IE Security Zones, an
attacker can create a malicious web site with a specially formatted
XMLHTTP GET request that would redirect the request to the user's
local system and read any file whose name and location was known.

3.3 MS02-009: Incorrect VBScript Handling in IE can Allow Web Pages
to Read Local Files
- released 21 February 2002
- updated 13 March 2002 (issues with third party software,
modified patch)
Risk: ****CRITICAL
- Internet systems: MODERATE
- Intranet systems: MODERATE
- Client systems: CRITICAL
Impact: information disclosure
Systems Affected:
- Internet Explorer 6.0
- Internet Explorer 5.5
- Internet Explorer 5.01
- Earlier versions are no longer supported, have not been tested,
and may or may not be vulnerable.
Summary:
A flaw exists in the way that Internet Explorer handles VBScript when
checking for cross-domain access. This flaw allows scripts contained
in a frame from one domain to access the contents of a frame in a
different domain - an action that should be prohibited. This could
allow an attacker to construct a malicious web site or HTML email that
could read any file on the local system that can be displayed in a
browser and whose name and location were known. It could also allow
the attacker to access information displayed in the user's browser
after the user left the attacker's web site, including usernames,
passwords, or credit card information. Outlook 2002, Outlook Express
6, and Outlook 98/2000 with the Email Security Update patch installed
are not affected by email versions of this attack.

3.4 MS02-010: Unchecked Buffer in ISAPI Filter Could Allow Commerce
Server Compromise
- released 21 February 2002
Risk: ****CRITICAL
- Internet systems: CRITICAL
- Intranet systems: CRITICAL
- Client systems: n/a
Impact: run code of attacker's choice
Systems Affected:
- Commerce Server 2000
Summary:
Microsoft Commerce Server includes an ISAPI filter called
AuthFilter that is used to manage various authentication methods.
A buffer overflow exists in the code that handles certain types of
authentication requests. Overflowing the buffer could cause the
server to crash, or possibly allow an attacker to run arbitrary
code on the system. Because Commerce Server runs in the context of
LOCALSYSTEM, this could give the attacker full control of the server.
Note that while the AuthFilter ISAPI filter is installed by default,
it must be specifically enabled for a given web site. Also, if the
URLScan tool is installed using the default rule set for Commerce
Server, it would restrict the type of data that could be input during
authentication, and prevent the execution of arbitrary code; however,
it would still be possible to crash the server.

3.5 MS02-013: Java Applet Can Redirect Browser Traffic
- released 4 March 2002
- re-released 18 March 2002 (second vulnerability discovered)
Risk: ****CRITICAL
- Internet systems: MODERATE
- Intranet systems: MODERATE
- Client systems: CRITICAL
Impact: information disclosure; run code of attacker's choice
Systems Affected:
- Microsoft Virtual Machine (VM) through build 3802. VM is included
in Internet Explorer. Versions of the VM shipping with IE 5.0 and
later were tested and found vulnerable.
- The version of VM installed can be determined by running the command
"jview" (without the quotes) at a command prompt; the version appears
at the far right of the first line of output.
Summary:
Microsoft Virtual Machine, included as part of Internet Explorer,
contains a flaw in the way a Java applet handles proxy requests.
An attacker could use a malicious Java applet to re-route all traffic
from the user's browser to the applet's host. The attacker could then
perform any action on the captured traffic: discard it (denial of
service), monitor the traffic for sensitive information (usernames,
passwords, credit card information), record the session for later use
(replay attack), or create bogus responses to the traffic (session
hijacking, man-in-the-middle). IE is only vulnerable when it is
used in conjunction with a proxy server. Because the flaw lies in
the underlying Java technology (implemented in VM), other systems
that use Java technology may also be vulnerable, including Netscape
Communicator 4.79 and earlier.
A second vulnerability was discovered and released in the revised
bulletin of 18 March. This vulnerability is a variant of the Virtual
Machine Verifier issue first discussed in MS99-045. A flaw exists in
the security checks that are performed on casting operations, which
can be used to convert data types, for example. It is possible for
a specially crafted malicious Java applet to execute code outside
the Java sandbox, potentially taking any action on the system that
could be taken by the current user.

3.6 MS02-004: Unchecked Buffer in Telnet Server Could Lead to Arbitrary
Code Execution
- released 2 February 2002
Risk: **MODERATE
- Internet systems: MODERATE
- Intranet systems: MODERATE
- Client systems: MODERATE
Impact: denial of service; run code of attacker's choice
Systems Affected:
- telnet server service in Windows 2000
- telnet daemon in Microsoft Interix 2.2
- Microsoft Services for Unix 2.0 is NOT affected by this
vulnerability
Summary:
A buffer overflow exists in the code that handles protocol options in
the Microsoft telnet server/daemon. An attacker who sent a specially
malformed packet to the telnet server could cause the service to crash,
or potentially run arbitrary code on the server. The code would
execute in the context of the telnet service (SYSTEM on Windows 2000;
can be set by the administrator on Interix 2.2). By default, the
telnet server is installed but disabled on Windows 2000. The telnet
daemon is not installed by default with Interix 2.2. Blocking requests
to TCP port 23 at the perimeter will mitigate this vulnerability.

Impact: denial of service; possible buffer overflow
Systems Affected:
- Windows XP
- Windows 2000
- Windows NT, including Terminal Server Edition (TSE)
- Windows 95/98/98SE
Summary:
A buffer overflow exists in the implementation of the Simple Network
Management Protocol (SNMP) in all versions of Windows. An attack can
send a malformed management request to an SNMP system to cause denial
of service, or possibly execute code in the LOCAL SYSTEM context.
Although SNMP is included in all versions of Windows except for
Windows Me, it is not installed by default. Blocking SNMP ports at
your perimeter will mitigate external attacks. See item 1.1 above
for additional information.

3.8 MS02-007: SQL Server Remote Data Source Function Contain Unchecked
Buffers - released 20 February 2002
Risk: **MODERATE
- Internet systems: MODERATE
- Intranet systems: MODERATE
- Client systems: MODERATE
Impact: run code of attacker's choice
Systems Affected:
- SQL Server 2000
- SQL Server 7.0
- Previous versions are no longer supported, were not tested, and
may or may not be vulnerable.
Summary:
The Structured Query Language (SQL) implementation in SQL Server 7.0
and 2000 allows queries to be created that establish on-the-fly ("ad
hoc") connections to remote data sources by naming a specific OLE
DB provider within the query. A buffer overflow exists in the code
that handles the OLE DB provider names. This could allow someone
with the ability to construct and submit a malicious query to cause
denial of service or execute code in the context of the SQL Server
(by default, a domain user).

3.9 MS02-014: Unchecked Buffer in Windows Shell Could Lead to Code
Execution
- released 7 March 2002
Risk: **MODERATE
- Internet systems: LOW
- Intranet systems: MODERATE
- Client systems: MODERATE
Impact: denial of service, run code of attacker's choice
Systems Affected:
- Windows 2000
- Windows NT and NT Terminal Server Edition
- Windows 98 and 98 Second Edition
Summary:
eEye Digital Security has discovered a buffer overrun in the Windows
Shell on several Windows systems. The buffer overflow exists in the
code that locates applications that have not been completely removed
when the application is uninstalled. In most cases, an attacker would
require local access to the system to exploit this vulnerability.
However, if an application using custom URL handlers (that allowed
an application to be launched via a specially formatted URL) was
uninstalled and did not uninstall completely, there is a slight
possibility that the vulnerability could be exploited via a malicious
web page or HTML email.

- Client systems: LOW
Impact: denial of service
Systems Affected:
- Microsoft Office v.X for Macintosh
- Microsoft Office 98 for Macintosh is NOT vulnerable
- Microsoft Office 2001 for Macintosh is NOT vulnerable
- Other versions are no longer supported, were not tested, and may
or may not be vulnerable.
Summary:
Microsoft Office v.X for Macintosh includes an anti-piracy mechanism
called the Network Product ID (PID) Checker. This feature causes
systems running Office v.X for Macintosh to periodically broadcast
their Product Identifier (PID) and to listen for other systems on the
network with the same PID. If a duplicate PID is detected, Office
will shut down. A specially malformed announcement can be used to
crash the Network PID Checker, which will crash the running Office
v.X application.

3.11 MS02-003: Exchange 2000 System Attendant Incorrectly Sets Remote
Registry Permissions
- released 7 February 2002
Risk: **LOW

Impact: insecure default settings
Systems Affected:
- Microsoft Exchange 2000
- Microsoft Exchange 5.5 is NOT vulnerable
- Previous versions are no longer supported, were not tested, and
may or may not be vulnerable
Summary:
The Microsoft Exchange System Attendant is one of the core services
in Microsoft Exchange. As one of its functions, the System Attendant
facilitates remote administration of Exchange servers by modifying
permissions on the "winreg" key in the Windows registry to allow
Exchange Administrators to modify Exchange configuration settings that
are stored in the registry from a remote system. The System Attendant
erroneously grants the "Everyone" group permissions to the winreg key,
which gives any user or group permission to connect remotely to the
registry. An attacker could potentially make changes to the registry,
depending on the permissions set on other registry keys. The attacker
must be able to use SMB to establish the remote connection, so blocking
TCP ports 139 and 445 at the perimeter would mitigate external attacks.

- Other systems were not tested, are no longer supported, and may
or may not be vulnerable.
Summary:
The SMTP service that is installed by default with Windows 2000 Server,
and installed with the Internet Mail Connector (IMC) of Exchange 5.5,
contains a flaw in the security checks that should be performed before
granting access to the SMTP service. Once the SMTP service or the
IMC are notified that a user has been granted access to the server
(via NTLM authentication), they should perform additional checks
to determine whether the user has permission to access the SMTP
service/IMC itself. These checks are not performed, which could
result in unauthorized access to the SMTP service.

4.1.1 Microsoft Windows 2000 Password Policy Bypass Vulnerability
* Risk: LOW
* Impact: password reuse
* Summary: Windows 2000 password policy can be set to prohibit reuse
of previous passwords (password history). If a user changes his or
her password before it expires (and s/he is prompted by Windows to
change the password), the password history check is not performed.
Passwords must still meet all other security requirements.

4.1.3 Microsoft Windows NTFS File Hiding Vulnerability
* Risk: LOW
* Impact: creation of hidden/inaccessible data
* Summary: Microsoft Windows operating systems enforce a 256 character
limit on any path/file name. However, using a drive mapped to a
directory created with the SUBST command, it is possible to create
directories/subdirectories such that the absolute path name exceeds
255 characters. Utilities such as anti-virus software will fail
to scan these long paths; if the drive mapping to the directory is
deleted, the files may become completely inaccessible.

* Summary: It is possible to send data - including attachments -
in the subject line of an Outlook Express email by encapsulating
the data within carriage return (<CR>) tags. Outlook Express will
interpret information following the carriage return as the data
portion of the email. Because mail filtering tools do not parse the
subject line for malicious content, this could allow an attacker to
send malicious code that would bypass filters.

6. Third-Party Software Issues
6.1 Buffer Overflows
* Risk: HIGH
Buffer overflows can generally be used to execute arbitrary code
on the victim host; as such, they should be considered HIGH risk.
Many buffer overflows are discovered each month. We report the ones
we know about here. In addition, we have tried to give you a little
more information in a concise format. To that end, certain items are
marked with an (F) and/or (E). (E) means that an exploit for this issue
is publicly available. (F) means that a fix is currently available.
6.1.1 Internet Security Systems BlackICE and RealSecure Buffer Overflow
(F,E)
* Summary: Versions of BlackICE Defender, BlackICE Agent, and
RealSecure Server Sensor running on various Windows platforms are
subject to denial of service attacks through a "ping flood" where
large ICMP Echo Request (ping) packets are sent to the target system.
The attacker can crash the target system; specially crafted packets
can execute code in the context of the target system's kernel.
Blocking ICMP Echo Requests at the perimeter will mitigate external
attacks; ISS has also provided a workaround to block ICMP Echo Requests
on the agents themselves, though a patch is also available.

6.2.10 FastTrack P2P Technology Multiple Vulnerabilities
* Risk: LOW
* Impact: identity spoofing; denial of service
* Summary: FastTrack P2P technology forms the basis for various file
sharing clients such as FastTrack KaZaA, Grokster, and Music City
Networks Morpheus. Two vulnerabilities have been discovered in the
underlying FastTrack components. In the first, it is possible to
spoof the identity of another user by crafting an HTTP GET request
with bogus authentication information in the header. FastTrack is
also vulnerable to denial of service attacks caused by sending multiple
message requests to a vulnerable client to starve system resources.
