The problem has been discovered in the Virtual DOS Machine (VDM) introduced in 1993 to support 16-bit applications (real mode applications for 8086). VDM is based on the Virtual 8086 Mode (VM86) in 80386 processors and, among other things, intercepts hardware routines such as BIOS calls. Google security team member Tavis Ormandy has found several vulnerabilities in this implementation that allow an unprivileged 16-bit program to manipulate the kernel stack of each process via a number of tricks. This potentially enables attackers to execute code at system privilege level.

In addition to the unpatched hole in Internet Explorer, a now published hole in Windows allows users with restricted access to escalate their privileges to system level – and this is believed to be possible on all 32-bit versions of Windows from Windows NT 3.1 up to, and including Windows 7. While the vulnerability is likely to affect home users in only a minor way, the administrators of corporate networks will probably have their hands full this week.

The problem is caused by flaws in the Virtual DOS Machine (VDM) introduced in 1993 to support 16-bit applications (real mode applications for 8086). VDM is based on the Virtual 8086 Mode (VM86) in 80386 processors and, among other things, intercepts hardware routines such as BIOS calls. Google security team member Tavis Ormandy has found several vulnerabilities in this implementation that allow an unprivileged 16-bit program to manipulate the kernel stack of each process via a number of tricks. This potentially enables attackers to execute code at system privilege level.

Ormandy has also published a suitable exploit which functions under Windows XP, Windows Server 2003 and 2008, Windows Vista and Windows 7. When tested by the The H’s associates at heise Security, the exploit opened a command prompt in the system context, which has the highest privilege level, under Windows XP and Windows 7. No patch has become available, although Ormandy reports that Microsoft was already informed of the hole in mid 2009. The developer decided to publish the information regardless because, in his opinion, there is a simple workaround: to disable the MS-DOS subsystem.

The workaround requires users to start the group policy editor and enable the “Prevent access to 16-bit applications” option in the Computer Configuration\Administrative Templates\Windows Components\Application Compatibility section. When tested with these settings by the heise Security team, the exploit no longer functioned. The settings reportedly don’t cause any major compatibility problems for most users while no 16-bit applications are being used.

Update – The above option is only available through the group policy editor on Windows 2003 systems. Some versions of Windows do not include a group policy editor. As an alternative, users can also create a registry key under \HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\AppCompat with a D-Word value of VDMDissallowed = 1. Under Windows XP, to prevent the system from being vulnerable to the exploit, users can place the following text:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\AppCompat]

“VDMDisallowed”=dword:00000001

into a file called vdmdisallow.reg and double click the file. Windows will then automatically import the key (admin rights are required to perform this action).

Update 2 - Microsoft has now confirmed the privilege escalation hole in Windows. The company says that it wants to complete its investigation of the vulnerability and will then decide whether, how and when to close it.

• Microsoft Windows NT #GP Trap Handler Allows Users to Switch Kernel Stack, security advisory from Travis Ormandy.

REDMOND — When it rains, it pours. Especially in the Seattle area. Tavis Ormandy has published full details on a privilege escalation hack of all versions of Windows including Windows 7.

The exploit takes advantage of a bug in the Windows implementation of the ‘virtual DOS machine’ used to run legacy 16-bit programs. The exploit can be avoided by turning the VDM ‘feature’ off but the danger of course is that enough Windows lusers won’t know about the bug and/or bother turning the ‘feature’ off.

16-bit applications need BIOS support; the Windows kernel supports virtual BIOS interrupts in its ‘Virtual-8086′ mode monitor code. The code is implemented in two stages. The #GP trap handler transitions to the second stage when CS:EIP faults with specific ‘magic’ values.

The transition requires (subsequent to authentication) restoring the context and the call stack from the faulting trap frame. But the authentication process is flawed, relying as it does on three incorrect assumptions.

• Setting up a VDM context requires SeTcbPrivilege.The barrier to getting a VDM context can be subverted by requesting the NT VDM subsystem and then using CreateRemoteThread() to run code in the context of the VDM subsystem. The VDM subsystem already has the necessary flag set.
• Ring 3 (unprivileged) code cannot install arbitrary code segment selectors.Using the two least significant bits of CS/SS to calculate the privilege of a task doesn’t work when it comes to Virtual-8086 mode. The 20-bit addressing (by adding CS << 4 to the 16-bit IP) is also used to map onto the protected linear Virtual-8086 address space. If CS can be set to an arbitrary value, then the privilege calculation can be circumvented.
• Ring 3 (unprivileged) code cannot forge a trap frame.Returns to user mode are through IRET. An invalid context can cause IRET to fail pre-commit, which in turn forges a trap frame. And even with address randomisation it’s trivial to use NtQuerySystemInformation() to obtain the address of the second stage BIOS handler.

Affected Systems

This bug dates back 17 years and affects all systems released since 27 July 1993 – Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, and Windows 7. See the links below for further details.

Recently I have been been sorting through some of my old electronic engineering books and found myself randomly flicking through circuit design principals and practical electronics/radio theory application of calculus.

I remember the amount of hours I spent trying to get the different laws (Faraday, Coulomb, Kirchhoff, Lenz, Ohm, etc.) stuck in my head ready for the gruelling exams at the end of each term. I quickly realised that as I have moved from radio/electronics to the computer industry that most of my applied detailed knowledge has been lost.

I think the old adage that you loose it if you don’t use it, definitely applies here.

This got me thinking about the evolution of computing and the Internet and how there are many parallels to the introduction of electricity to the modern world and how we consider/use the Internet today.

Examples that came to mind are:

• Electricity was originally only available to business and the very wealthy
• Electricity was originally only available in isolated segments of heavily populated areas
• Electricity grids, once created, provided many more distribution opportunities, introduced redundancy and increased the customer reach which in-turn provided economies of scale to drive down costs
• Modern society can not function without electricity
• Electricity production methods and the resulting pollution has had a profound effect on our planet, where the production of consumer electronics and infrastructure supporting the never ending thirst of modern society for faster, more feature rich, communication methods. This is still spiralling out of control through the production of extraordinary high levels of non-recyclable waist, heavy metals and other planet destroying bi-products
• Electricity has been essential to survive in modern day society for some time.

The internet is quickly becoming (some would argue has become) essential to survival in our modern society and required to be available to all socio-economic groups and developing countries to allow them to participate in the global economy.

But at what cost?

Recently I have been looking into the vulnerabilities in the TLS negotiation process discovered late last year.

There are a range of experts debating the exploit methods, tools and how it may be fixed (server or client site or both). From what I have seen so far this may prompt a change to the TLS standard to introduce an extension to the protocol to validate sessions (session hand off and certificate validity).

www.ietf.org

isc.sans.org

• The original description (site is suffering from a slashdot effect as I write this)
• The summary by the IETF TLS workgroup, and promises for an amended protocol
• Marsh Ray’s paper
• March Ray’s protocol diagrams

www.win.tue.nl/hashclash/rogue-ca/

www.sslshopper.com/article-ssl-and-tls-renegotiation-vulnerability-discovered.html

I’m also trying to find some tools which may assist in testing for this. It looks like the exploit relies on an ARP poison or similar and then inserting plain text into the negotiation process.

Could be something that can be fixed over time as servers and clients are patched.

This is something which could be useful going into fire season here in South Australia. It is a feed from the SA government trunk radio network.

I will see if there are more feeds like this that also include the regional and remote area trunks. This sounds like the Adelaide CBD feed.

SETI http://www.setileague.org/homepg.htm

SETI Australia http://www.seti.org.au/

This is a presentation I gave on SCADA security some time ago. It was originally set for about 2 hrs, although I broke it into 2 halves so if time permitted (or the partisipants wanted more inforamation), the backend of the presentation has many more areas and guidence relaing to SCADA, devices, environment security, etc.

I defined the following outcomes for the presentation:

• Broaden the awareness and necessity of security within the SCADA environment.
• Understanding of business role in the governance/risk identification process.
• Heighten the understanding of technology risks.

I hope people find the material interesting and useful.

SCADA Security Presentation Derek Grocke

I have been working in the SCADA engineering, network design, project governance and security area for lots of years.

As a result I have many documents and techniques I will be sharing here. This is the first of many documents which I hope others will find informative and help others to understand and shape their approach to these environments.

Local file

SCADA Presentation

A cool document I thought I would share. It shows some good understanding and presents some good ideas.

General Questions

• How can users gain access to the SCADA application?
• Objective to consolidate access to all information sources – i.e. to make access available to all users via a single interface
• Are any RAS modems utilised within the SCADA environment?
• Is the RAS call back feature utilised?
• Is the mandatory RAS encryption feature used?
• Are users allowed multiple attempts at authentication on the RAS?
• Has the RAS auditing feature been enabled?
• How is access between the business / corporate network and SCADA network controlled?
• How is the administrator password controlled?
• How is vendor access to the SCADA network controlled – i.e. password changes after contract has been completed?
• Are SLA’s for outsourced support agreements reviewed on a periodic basis?
• Are critical components of the SCADA Network supported by a UPS and are these batteries tested on a regular basis to ensure that they are reliable?
• What capacity management and monitoring of critical SCADA network systems is performed (i.e. CPU utilisation and hard disk drive space)?
• Are legal captions utilised during the login process to the SCADA application and associated infrastructure / devices?
• Has an intrusion detection system (IDS) been deployed within the SCADA environment?
• Has security been a focus within the development and deployment of the SCADA network?
• Is there additional staff screenings performed when staff are hired to work within the SCADA environment (inclusive of vendors etc)?

Policies & Procedures

• Is there a defined security strategy for the SCADA environment?
• Who is responsible / accountable for security management within SCADA environment? Has the ownership of this responsibility been clearly defined and/or stated in any documentation?
• Are there any periodic security reviews of the SCADA network performed?
• What procedures are in place to handle the disposal of SCADA network media and devices? Additionally, is there a process in place for the disposal of confidential information / documentation?
• Are there any policies or procedures covering the introduction of new devices to the SCADA environment?
• What formal change control procedures exist for the SCADA environment?
• Does a formal disaster recovery plan exist for the SCADA environment?
• Does a formal business continuity plan exist for the SCADA environment?
• Do physical and logical security standards differ significantly between SCADA sites?
• Has a standard operating environment (SOE) minimum baseline standard been developed for systems being introduced into the SCADA environment?
• What security logs are maintained for critical computer equipment and how often are the logs reviewed?
• Who is responsible for the reviewing of security logs?
• Has access to event logs been restricted?
• Upon commencement of employment, are users provided with IT security information as part of the induction process? Additionally, are users provided with further information on security issues on a periodic basis?
• What procedures exist to monitor dial-in access?
• Is there a formally defined backup and recovery procedure?
• Are encryption techniques and/or passwords applied to backup tapes?

Physical Access

• How is physical access to SCADA terminals controlled?
• Are SCADA control rooms segregated from other rooms?
• What building security exists at remote sites to prevent unauthorised access?
• What authentication methods are used at remote sites to allow access – i.e. swipe cards?
• Are external windows at remotes sites barred?
• What alarm systems have been employed at remote sites?

Network Security

• Have all deployed routers been configured to ensure the filtering of communications that are unauthorised or not required?
• What traffic control and monitoring capabilities have been deployed – i.e. all communication travels to a central point before traversing further on the network.
• How are dial-in facilities to the SCADA environment secured?
• How is suspicious or unusual activity on the SCADA WAN detected?
• What firewall configurations have been set up to segregate the SCADA WAN from the United Water corporate network?
• Are all key filtering devices on the network (such as routers and firewalls) configured to log all attempts to access the network? If so are they reviewed on a regular basis?
• Have the auditing features of all routers and firewalls been enabled?
• Has access to event logs been restricted?
• How is the management of patches / hot fixes controlled in regards to firewalls and routers?
• What backup and recovery measures are in place for network resources – firewalls and routers?
• Has SNMP been implemented on core infrastructure?
• Has any wireless equipment been deployed within the SCADA environment – has this been configured to a secure state?
