1. IN FOCUS
(contributed by Mark Joseph Edwards, News Editor, [email protected])
I've discussed honeypots several times in the Security UPDATE newsletter. Now, several organizations are developing another type of honeypot to trap intruders. The Science Applications International Corporation (SAIC) has established the Wireless Information Security Experiment (WISE), which runs under the 802.11b wireless communication specification. According to SAIC, the new wireless honeypot network "sits behind a device where all inbound and outbound data is controlled and captured. \[The\] information is then analyzed to learn the tools, tactics, and motives of wireless system exploitation in order to develop information security tools and defenses."
In the March 27, 2002, edition of Security UPDATE, I discussed "war driving" (see the URL below), a phrase that describes the act of driving around with a wireless connectivity device with an antenna attempting to connect to unprotected wireless LANs (WLANs). SAIC's wireless honeypot is a response to intruders who perform war driving. WISE will be located in a major metropolitan area in which war drivers often search for vulnerable networks. The WISE honeypot network, designed to "develop effective information security, intrusion detection, and incident response, and forensic methodologies for wireless networks," will consist of several bridged wireless nodes designed to cover a large city area. SAIC will eventually connect the wireless honeypot to a satellite broadband system that will in turn connect the initial honeypot network to a similar network in another major city.
SAIC's wireless honeypot is part of the Honeynet Research Alliance, a group of organizations "actively researching, developing and deploying Honeynets and sharing the lessons learned." The alliance currently consists of 10 organizations around the world, each of which is involved in various aspects of honeypot development and research. Alliance members include the South Florida HoneyNet Project, Nodal Intrusion Forensics Technology Initiative, Incidents.org Virtual Honeynet Project, Paladion Networks Honeynet Project, Internet Systematics Lab Honeynet Project, SAIC Wireless Honeynet, AT&T Mexico Honeynet, NetForensics Honeynet, Azusa Pacific University Honeynet, and the Brazilian Honeynet Project. You'll find more information about honeypots and the alliance at the first URL below. Check out the Web site, especially if you're considering establishing a honeypot or honeynet of your own.

Did you know that Microsoft has changed how users submit vulnerability reports? Formerly, users emailed vulnerability information to [email protected] However, the company recently removed that contact address from its Web site and now requests that users contact the company about security vulnerabilities through a Secure Sockets Layer (SSL)-enabled Web form. The new Web form will help the company collect more complete information for vulnerability reports through the many fields that users must complete before they submit a report. For example, when you visit the Web page, you'll find that the form requests information such as OS, additional hardware installed on the system, and installed security patches and service packs. The form also provides space in which to describe how someone could mount an attack by using a given flaw and what results would occur. Be sure to look at the new form at the URL below. During the transition to the new Web form, the company will still monitor the [email protected] email address.

2. SECURITY RISKS
(contributed by Ken Pfeil, [email protected])
Dan Pascal Huijbers and Thomas de Klerk of Info Support discovered a flaw that could let an unprivileged user access and manipulate data within Microsoft Metadirectory Services (MMS) that, by design, only MMS administrators should be able to access. Microsoft has released Security Bulletin MS02-036 (Authentication Flaw in Microsoft Metadirectory Services Could Allow Privilege Elevation) to address this vulnerability and recommends that affected users download and apply the service pack mentioned in the security bulletin.
Cesar Cerrudo discovered two vulnerabilities in Microsoft SQL Server 2000 and Microsoft SQL Server Desktop Engine (MSDE). The vulnerabilities are related to a buffer overrun and SQL injection. Microsoft has released Security Bulletin MS02-038 (Unchecked Buffer in SQL Server 2000 Utilities Could Allow Code Execution) to address these vulnerabilities and recommends that affected users download and apply the appropriate patch mentioned in the security bulletin.
Cesar Cerrudo discovered three new vulnerabilities in Microsoft SQL Server 2000 and Microsoft SQL Server Desktop Engine (MSDE). The vulnerabilities are two buffer overruns and a potential for Denial of Service (DoS) attacks. Microsoft has released Security Bulletin MS02-039 (Buffer Overruns in SQL Server 2000 Resolution Service Could Enable Code Execution) to address this vulnerability and recommends that affected users download and apply the appropriate patch mentioned in the security bulletin.
Dan Ingevaldson of Internet Security Systems (ISS) discovered a buffer-overrun vulnerability in Microsoft Exchange Server 5.5 that can let an attacker remotely compromise the server. This vulnerability is the result of an unchecked buffer in the Internet Mail Connector (IMC) code that generates the response to the Extended Hello protocol command. Microsoft has released Security Bulletin MS02-037 (Server Response To SMTP Client EHLO Command Results In Buffer Overrun) to address this vulnerability and recommends that affected users download and apply the appropriate patch mentioned in the bulletin.
We apologize for inadvertently misspelling Symantec's name in the July 24, 2002, edition of Security UPDATE as we described a vulnerability in Symantec's Norton Personal Firewall that an attacker can exploit to execute code on the vulnerable system. We appreciate those readers who pointed out the error.

4. SECURITY ROUNDUP
A bizarre rumor about Microsoft making sweeping changing to its Windows Product Activation (WPA) technology in Windows XP Service Pack 1 (SP1) is completely untrue, the company has stated. The rumor, which a small technology-enthusiast Web site started, had Microsoft changing the product keys for all its customers who use volume licensing.
Today's centrally managed, software-based firewalls go well beyond packet filtering. Although interrogating a network datagram for IP addresses and port numbers is still a prerequisite, vendors, such as those in this firewall software Buyer's Guide, are including more functionality. To distinguish between excellent and run-of-the-mill firewalls, you need to look at a product's level of automation, additional features, and ease of management.

A. Microsoft Security Bulletin MS02-032 (Cumulative Patch for Windows Media Player) identifies several version-specific patches to secure Windows Media Player (WMP) against script attacks. To manually disable WMP's HTML-processing feature, perform the following steps:
- Start a registry editor (e.g., regedit.exe).
- Navigate to the HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences registry subkey.
- From the Edit menu, select New, DWORD Value.
- Enter a name of PlayerScriptCommandsEnabled, then press Enter.
- Double-click the new value, set it to 0 to prevent WMP from processing HTML scripts in media files, then click OK.
- Close the registry editor.
- Restart WMP.
7. NEW AND IMPROVED
(contributed by Judy Drennen, [email protected])
GFI's Email Security Testing Zone launched three new free email tests. Administrators can test whether their networks are protected against attacks using the Iframe Remote and Object Codebase exploits and whether their antivirus software is working. Email users can sign up for these tests by submitting their names and email addresses to GFI's Email Security Testing Zone.
Abtrusion Security announced Abtrusion Protector, an intrusion and virus protection software for Windows NT OSs. The software verifies that a file is permitted to execute.

8. HOT THREADS
Featured Thread: Recovery Console Password Recovery
(One message in this thread)
Kris believes that when he promotes a Windows 2000 server to a domain controller (DC), the local Administrator account is no longer accessible but might still be used for functions such as booting to the Recovery Console (RC) and restoring Active Directory (AD). Kris wants to know whether this is true and, if so, how he can get to the LAN Manager (LM)/NT LAN Manager (NTLM) hashes for the local Administrator account to run a password cracker against it.
