In Focus: Is Trustworthy Computing Trustworthy Yet? ==== by Mark Joseph Edwards, News Editor, markat_private Microsoft recently launched the Windows Server 2003 OS. It's probably the company's best effort to date at rolling out a secure product. So far, no one has reported security problems with the new OS, but it's still early. Attackers haven't yet hammered on Windows 2003 enough to determine whether its armor has chinks. However, Microsoft's effort to establish itself as a maker of trustworthy computing products has encountered some other difficulties. As you'll learn from the news story "Hotmail and .NET Passport Open to Account Theft?" in this week's Security UPDATE, Microsoft Passport has an exploitable vulnerability. The Passport problem's simplicity shows that developers didn't think broadly enough about how attackers might try to subvert Passport security. Microsoft has corrected the problem, which is good--but I'm sure Passport account holders wonder whether the service contains other problems. The NTBugtraq mailing list recently brought to light a second trustworthiness problem--with the Windows Update service. Countless users rely on the service to obtain patches for their Microsoft products. On May 12, Bob Terry posted a message to the list stating that while he was patching systems, Windows Update began reporting back to his systems that no updates were available. He wondered whether the service was down. NTBugtraq Editor Russ Cooper posted a reply stating that many other users were reporting similar problems. After comparing notes with other users and checking further, Cooper posted another message to the list that summarizes his findings. He discovered that many users had to tweak various aspects of their systems and perform secondary or tertiary checks to determine whether their systems were up-to-date. Below you'll find what Cooper had to say, excerpted for brevity (you can read Cooper's entire post at the URL below): http://ntbugtraq.ntadvice.com/default.asp?pid=36&sid=1&A2=ind0305&L=ntbugtraq&F=P&S=&P=4505 "For at least the past several days, Windows Update has been providing consumers with false information. Windows Update users would connect [and] initiate the scan. [The scan] would complete and inform [users that] their system needed no patches. Wonderful, a clean bill of health, or so the consumer thought. "In reality, some flaw in the Windows Update process has led it to conclude that a system in need of critical security patches is instead clean and good to go on the Internet. In other words, if the security check fails, tell consumers they're just fine and don't need anything ... "You wouldn't believe the number of individual [reports about problems with Windows Update] I've received. No doubt Microsoft receives far more than I do. I can't believe that huge corporations are having the problems they are, nor can I believe they haven't received a reasonable answer from Microsoft as to why the problems exist ... "If [those at Microsoft were] serious about beginning to tackle the trustworthiness of Microsoft, they'd have done something a year ago when I first called Windows Update a dog. See for yourself, look at my previous musings [see the URLs below], then tell me what's been fixed or improved. If, like me, you see nothing ... then the Trustworthy Computing Initiative once again gets an 'F'." http://ntbugtraq.ntadvice.com/default.asp?pid=36&sid=1&A2=ind0204&L=ntbugtraq&F=P&S=&P=6886 http://ntbugtraq.ntadvice.com/default.asp?pid=36&sid=1&A2=ind0204&L=ntbugtraq&F=P&S=&P=6990 Cooper makes some reasonable observations and valid points. If Windows Update doesn't behave properly, Microsoft should return a message stating that the service is experiencing a problem instead of returning the ambiguous message "no updates available." The Passport vulnerability and the Windows Update errors seem to reveal a lack of perspective on Microsoft's part. Granted, software will continue to have flaws. However, if we're to trust Microsoft's secure computing initiative as the company undoubtedly wants us to, then Microsoft's software and services must become more secure--and that security includes being more informative.

Security Risks ==== contributed by Ken Pfeil, kenat_private Arbitrary Code Execution Vulnerability in Microsoft WMP Jouko Pynnonen and Jelmer discovered that a vulnerability in Windows Media Player (WMP) 8.0 and WMP 7.1 can result in the execution of arbitrary code on the vulnerable system. This vulnerability stems from a flaw in the way WMP handles the download of skin files. The flaw could let an attacker force a file (e.g., a malicious executable) masquerading as a skin file into a certain location on a user's machine. Microsoft has released Security Bulletin MS03-017 (Flaw in Windows Media Player Skins Downloading could allow Code Execution) to address this vulnerability. http://www.secadministrator.com/articles/index.cfm?articleid=38993 Multiple Vulnerabilities in Cisco VPN 3000 Series VPN Concentrators Multiple vulnerabilities exist in the Cisco VPN 3000 Series Concentrator, the most serious of which can let an attacker access the internal hosts on the IP Security (IPSec) over TCP-configured ports. The other two vulnerabilities can result in a Denial of Service (DoS) condition on the VPN Concentrator. Cisco Systems has released an advisory and a fix for affected customers, which you can obtain from the company's Web site. The company recommends that customers upgrade to fixed software versions, as detailed in this documentation. http://www.secadministrator.com/articles/index.cfm?articleid=38994 ==== 3.

Security Roundup ==== News: New Technology for the Packet Police Cisco Systems has introduced new technology that will let law enforcement agencies and ISPs police both networks and people. According to Cisco, one new capability already present in routers but not yet deployed is the ability to tap both IP telephony calls and data streams. Another is a new Bandwidth Processing Engine (BPE) for the company's uBR7246VXR Cable Modem Termination System (CMTS). http://www.secadministrator.com/articles/index.cfm?articleid=39020 News: Virtual Machine Security Melts in the Heat of Attack Sudhakar Govindavajhala and Andrew W. Appel presented a paper at the 2003 IEEE Symposium about Security Privacy that demonstrates a method of defeating security of virtual machine products such as Microsoft Virtual Machine (VM) and Sun Microsystems and IBM Java virtual machines. The men discovered that they could use a heat lamp to flip bits in memory chips, causing their own untrusted code to run within the virtual machine. http://www.secadministrator.com/articles/index.cfm?articleid=39024 News: It's a Worm, It's a Trojan Horse, It's a Keystroke Logger. It's Fizzer A new worm, dubbed Fizzer, is spreading around the Internet through email and peer-to-peer (P2P) networks. Fizzer carries quite a hostile payload compared with past worms. http://www.secadministrator.com/articles/index.cfm?articleid=39016 News: Hotmail and .NET Passport Open to Account Theft? According to a message posted by Muhammad Faisal Rauf Danka to the BugTraq mailing list, Microsoft's .NET Passport service is wide open to attackers who use a Passport user's Hotmail account to reset the password. Danka claims to have found a certain Passport URL that anyone can enter into a Web browser and thereby hijack a user's Passport account. Microsoft removed access to the vulnerable URL that Danka described. http://www.secadministrator.com/articles/index.cfm?articleid=39001 Feature: 5 Techniques for Establishing Highly Secure Systems Microsoft has documented five TCP registry modifications you can implement to reduce a Windows 2000 system's vulnerability to Denial of Service (DoS) attacks and other common exploits. These techniques are suitable for Win2K systems connected to a WAN or the Internet and for sites operating under strict security controls.

You need to first enable auditing for Audit logon events and Audit process tracking. Then, look in your event log for an event ID 592 (a new process has been created) for which where the image base filename is tlntsess.exe. Note the Logon ID, and scan the event log for an event ID 528 (successful logon) with the same Logon ID. The User Name in event ID 528 identifies who logged on using the Telnet service. ==== 6.

Hot Thread ==== Windows & .NET Magazine Online Forums http://www.winnetmag.com/forums Featured Thread: ISA Server Losing Persistent Route (Two messages in this thread) A user writes that he has Microsoft Internet Security and Acceleration (ISA) Server 2000, which he uses as a firewall, proxy, and VPN server. He had the same setup on Windows NT with Proxy Server 2.0 running. In that configuration, he never entered a default gateway in the IP settings of his local NIC. Instead, he entered a persistent route in the route table using the command shell "route" command. He has set up a new box with ISA Server and applied the same settings and theory he used with Proxy Server. However, he loses the persistent route every few days. When he uses the "route print" command, the route doesn't show up in the table. If he tries to add the route again using the "route -p add" command, he receives a response telling him that the route is already there. He wonders what the problem is.
