No need to bypass security with a boot disk – 17 year old Windows exploit found

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 â€“ 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 ConfigurationAdministrative TemplatesWindows ComponentsApplication 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_MACHINESOFTWAREPoliciesMicrosoftWindowsAppCompat 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_MACHINESOFTWAREPoliciesMicrosoftWindowsAppCompat]

“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 -Â 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.

SSLv3 / TLS Man in the Middle vulnerability

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.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.

Nmap Examples

Posted by :Derek On : September 2, 2009

Category: Infrastructure, Internet

Tags:data, DES, DNS, EFT, Hidden, Internet, ISP, network, Pin, RSA, security, server, text, type, web

Some Nmap examples I thought I would post.

Scanning past Watchguard Firewalls: nmap -sS -iL targetlist.txt -P0 -sV -T4

Verbose Scan: nmap -v

This option scans all reserved TCP ports on the target machine. The -v option enables verbose mode.

nmap -sS -O /24

Launches a stealth SYN scan against each machine that is up out of the 256 IPs on â€œclass Câ€ sized network where Scanme resides. It also tries to determine what operating system is running on each host that is up and running. This requires root privileges because of the SYN scan and OS detection.

nmap -sV -p 22,53,110,143,4564 198.116.0-255.1-127

Launches host enumeration and a TCP scan at the first half of each of the 255 possible eight-bit subnets in the 198.116 class B address space. This tests whether the systems run SSH, DNS, POP3, or IMAP on their standard ports, or anything on port 4564. For any of these ports found open, version detection is used to determine what application is running.

nmap -v -iR 100000 -PN -p 80

Asks Nmap to choose 100,000 hosts at random and scan them for web servers (port 80). Host enumeration is disabled with -PN since first sending a couple probes to determine whether a host is up is wasteful when you are only probing one port on each target host anyway.

nmap -PN -p80 -oX logs/pb-port80scan.xml -oG logs/pb-port80scan.gnmap 216.163.128.20/20

This scans 4096 IPs for any web servers (without pinging them) and saves the output in grepable and XML formats.

Instead of limiting ourselves to scanning just one target., let’s broaden our horizon’s to bigger and better things. In example 2 we used our IP address to base a scan against. Using that address again we can get a look at numerous targets in our “community”. At the command line type the following (substituting a valid address of your choice of course):

nmap -sT -O 206.212.15.0-50

What this does is instruct nmap to scan every host between the IP addresses of 206.212.15.0 and 206.212.15.50. If you happen to find many interesting feedback results from this or a larger scale scan then you can always pipe the output into your choice of a human readable file or a machine parsable file for future reference by issuing the following option:

To create a human readable output file issue the -oN command into your nmap string so that it would look similar to this:

nmap -sT -O -oN sample.txt 206.212.15.0-50

Rather have a machine parsable file? Enter the -oM to pipe the output into a machine parsable file:

nmap -sT -O -oM sample.txt 206.212.15.0-50

*Back when I was becoming aquatinted with all the nmap options, I ran my first large scale scan against 250 consecutive machines using an arbitrary number (nmap -sX -O -oN sample.txt XXX.XXX.XXX.0-250).To my great surprise I was confronted with 250 up and running virgin Linux machines. Another reason why Linux enthusiasts should NEVER become bored.

-I This is a handy little call that activates nmap’s TCP reverse ident scanning option. This divulges information that gives the username that owns available processes. Let’s take a look (Note that the host has to be running ident). At the command line issue this command against your target, in this case our default Eve running Linux:

-iR Use this command to instruct nmap to scan random hosts for you.

-p Port range option allows you to pick what port or ports you wish nmap to scan against.

-v Use verbosity to display more output data. Use twice (-v -v) for maximum verbosity.

-h Displays a quick reference of nmap’s calls

Now that we have looked at nmap’s three basic usage types and some of it’s other options, let’s mix and match them.

nmap -v -v -sS -O 209.212.53.50-100

This instructs nmap to use a maximum amount of verbosity to run a stealth scan and OS detection against all machines between IP addresses 209.212.53.50 and 209.212.53.100. This command will also require root privileges due to both the -sS and -O calls. Of course this will display a very overwhelming amount of data so let’s log our results into a human readable file for future reference:

nmap -v -v -sS -O -oN sample.txt 209.212.53.50-100

Now let’s make nmap run a stealth scan and instruct it to look only for machines offering http and ftp services between the addresses of 209.212.53.50 and 209.212.53.100. Once again we will log the output (I’m a log junkie) for future reference into a human readable file called ftphttpscan.txt:

nmap -sS -p 23,80 -oN ftphttpscan.txt 209.212.53.50-100

Remember the -iR option mentioned previously? Let’s use it to take a random sampling of Internet web servers using the verbatim example from nmap’s man page:

nmap -sS -iR -p 80

Last but certainly not least, while gleaning information, don’t forget to nmap yourself. Just type at the command line: nmap 127.0.0.1 This is especially useful and recommended if you’re a newcomer to Linux and connected to the Internet via DSL or cable modem.

Detect promiscuous network devices or sniffers on a network

Old versions nmap –script=promiscuous 10.0.1.0/24

New Versions nmap -sV –script=sniffer-detect 10.0.1.0/24

DUKPT Overview and Transaction notes

Hi,

I was asked on another post relating to DUKPT to provide some backgound. Given I have lots of material on the subject, I thought I would create this thread. Link

I will come back at some stage and expand on this when I get time.

Transaction Process narrative:

The diagram describes a mobile terminal/ATM is described using the a AS2805 (‘2805’) message type and 3DES DUKPT and dual direction auth SSL from the terminal to the aquirer (transaction switch).

A good explanation of DUKPT can also be found at Wikipedia.

Diagram of the flow

DUKPT transaction flow - terminal to bank

Background notes:

The terminal or ATM firstly encrypts the user entered pin (may be a unique DUKPT key or static, depending on the design and banks involved) prior to incorporating it into the AS 2805 transaction message.
the message is then encrypted again using the DUKPT key which has been established through the merchant logon process within the aquirer Host Security Module (HSM) i.e. the user entered pin is encrypted separately and encapsulated within the DUKPT encrypted 2805 message to provide full message encryption.
In the diagram a separate dual authenticating SSL session is also used between the terminal/ATM and the aquirers infrastructure. This allowing the transaction including the pin to traverse the external Wired/GPRS/LAN within 2 primary independent layers of encryption, with a 3^rd protecting the PIN.
When the transaction enters the aquirer environment the message encapsulation layer provided by SSL is removed.Â This leaving the DUKPTâ€™ed 2805 message which also encapsulates the separately encrypted PIN.
This encrypted message is passed to the aquirer switch engine through to the aquirer’s HSM for decryption of the 2805 message excluding the user entered pin.
This is when transactional information necessary for aquirerâ€™s merchant reporting (truncated card number, transaction amount, transaction type, etc.) and fraud management data is collected.
The aquirer switch then passes the encrypted PIN to the aquirer HSM requesting that the PIN be decrypted using the aquirer’s PIN encryption and translated to the next banks (Bank 1)Â PIN Encryption Key (Pin translation only occurs within the aquirer HSM) This is then sent back to the aquirer Switch engine as the Bank 1 encrypted PIN.
The aquirer switch engine then send the decrypted 2805 message with the newly encrypted PIN back to aquirer HSM to be encrypted with the Bank 1 MAC key.
The resultant Bank 1 key encrypted message is then sent to Bank 1 for processing and/or passing to the card issuer (using a similar process as described above).
When the result is received back from the issuing bank it is encrypted with the Bank 1 MAC key (the pin will not be present in the result message).
This is then decrypted by the aquirer HSM, the transaction fate result stored into the aquirer merchant reporting system and the transaction fate re-encrypted with the original aquirer DUKPT key (should be different per terminal/merchant instance) and the result sent back to the terminal through the original established SSL encrypted terminal connection.

The aquirer may terminate the the SSL connection on a hardware device such as a CISCO Content Service Switch (CSS), or equivalent instead of the design described in the diagram which terminates onto a SSL session server/gateway (Possibly including a Certificate Authority) or on the aquirer transaction switch.

When PIN blocks are received by the aquirer processing centre, the PIN encryption is translated from the terminal key to the Local Master Key (LMK) by the Host Security Modules (HSM).

When the message is sent on the upstream bank interchange link to the issuer or gateway , the aquirer HSM translates the encrypted PIN block from the LMK to the Zone Master Key (ZMK) of the aquirer interchange link. The PIN block is always encrypted using DEA3 (3DES) whenever outside of the Terminal or ATM.

I’m looking at the Microsoft OCS server and other SIP integration environments. So I thought I would put the links here for others who were interested. I am also considering the issues associated with Mitel VoIP and OCS integration.

It would be interesting if the Microsoft OCS could seamlessly allow the use of soft phones and the Mitel VoIP system. I assume a trunk needs to be setup between the two… Anyway something to look at.

EFT Syetms and Device Considerations

Posted by :Derek On : August 5, 2008

EFT devices and systems differ depending on hardware vendor, country and bank / payment aggregator.
Below is a list of things you may like to consider. This list is off the top of my head so it is probably not complete.

Looking at the products and relationships us usually a good start.

Things to consider:

Card skimming methods
Some EFT POS devices restrict the connection of a skimmer
Review levels of associated fraud
Review devices and EFT methods
Review terminal identification (merchant and customer)
Manual processing. (internal and external)
eCommerce products
PC based software
Dedicated server services (Nobil, etc.)
Web based engine (Custom objects, Web pop-ups, etc)
Authorisation / identification methods (Merchant and customer)
TCPIP session hijacking / session spoofing
Direct Debit as well as Credit Cards.
Swift (methods and controls)
Telegraphic transfer (methods and controls)
Payment aggregator relationships (eg. Payment Tech, manual processing, cheque scanning, etc.)
Internet banking facilities (attack / penetration,Â Certificate registration / management, ISP SLA’s, etc.)
Implementation of Smart Card and / or alternative customer recognition devices.
Outsourcing and associated risks / service level agreements
Payment processing
Payment clearance
Payment switching
Reporting (segregation of merchant / customers / aggregators / partners / local / international)
Fraud detection and reporting
3rd party acquiring risks
Single merchant ID many businesses
Allows moneys to be laundered if the payment aggregator does not place appropriate controls on the merchant.
Encryption used
Internet / trusted partner / inter-bank / extranet
Private and / or public certificates
Single use certificates
Client side certificates
Remittance advice processes and controls.
EFT disaster recovery and manual fall back procedures (associated security and reconciliation risks)
Trusted partner relationships, SLA’s, liabilities and risks.
EFT regulatory / legal requirements (inter-bank and government)
Refund processing / authorisation. (policies, procedures, controls, etc.)
CVV, CVV-2 / CVC-2 processing and management. (http://www.atlanticpayment.com/CVV.htm)
Fraud detection mechanism (neural networks, inter-bank / department customer checks, etc)
Supported card schemes (AMEX/Visa/Mastercard/Discover/etc )
Review EFT floor limits (corporate and SME merchants)
Review the ability to withhold merchant settlement until the presence of fraud has been determined.
Review customer identification details. Such as (This varies around the world depending on local regulations / privacy laws)
Review real-time and batched processing methods and controls (sequence numbers, access to raw data, etc.)
Review processing with and without expiry dates. (exception controls and policies)
Review exception / fraud reports.
Review payment store and forward policies and procedures.
Review Pre-Auth and Completion controls.
Token based payment (eCash, etc)
Merchant reconciliation, reporting methods and controls (paper, Internet, email, PDF, Fax, etc.) and associated security.
Real time gross settlement policies, procedures and controls. (IT and amounts)
Card issuing policies and procedures. (customer ID checks, etc)
Banking infrastructure (ingress / egress) controls and security. (Web, partner, payment switches, outsourced infrastructure, monitoring / reporting.)
Use of Internet technologies for inter-bank transfers and remote equipment.
Physical security and controls of devices, ATM,s, line encryptors, etc.
