[Full-disclosure] When is it valid to claim that a vulnerability leads to a remote attack?
A reputable security defect reporting organization is claiming that a Windows program is subject to a remote attack because: * The vulnerable program (call it 'pqrminder') is registered as the 'handler' for files with a specific extension (call it '.pqr'). * If the user downloads a '.pqr' file (or is sent on in the mail and clicks on it), then 'pqrminder' is invoked. * If the file is malformed, then arbitrary code can be executed (buffer overflow). While recognizing that there is a bug here, that does not strike me as being what is normally meant by a 'remote attack'. -- Jonathan Leffler (jleff...@us.ibm.com) STSM, Informix Database Engineering, IBM Information Management 4400 N First St, San Jose, CA 95134-1257 Tel: +1 408-956-2436 Tieline: 475-2436 "I don't suffer from insanity; I enjoy every minute of it!"___ Full-Disclosure - We believe in it.

Re: [Full-disclosure] When is it valid to claim that a vulnerability leads to a remote attack?
Hi Jonathan, IMHO it generally is classified as remote. Some vendors call it "user assisted remote arbitrary code execution" which, in my opinion is just downplaying the issue - there are virtually unlimited means to get somebody or something to open such a file some less assisted but still exploiting the issue at hand. If you want to find common ground with said person, propose the denomination above. This subject is indeed interesting and worth discussing, not sure FD is the best place though.

I concur with Thierry - the fact that one of the steps in the exploit is "get the user to click on it" does *not* mean the vendor can stick their head in the sand and claim it's not an issue. It just means the exploit will require a social engineering step as well as coding. If you think that it's hard to get users to run the program for you, consider that a very large community is making a lot of money sending users e-mail that says "please go to this web page and enter your userid, password, and credit card number so we can take all your money". Of course, they have to do a little work so it looks like it came from the victim's bank... pgpDlVnZEWtki.pgp Description: PGP signature ___ Full-Disclosure - We believe in it.

In fact it's very typical of the types of attacks we see every day now. By far the most routinely successful attacks now are initiated through some sort of social engineering trick that requires user interaction to trigger the compromise. If by remote you mean "live interaction by the hacker at the point of attack" (as in a "traditional" hack), then no, it's not a remote attack. I think the more normal undertstanding of remote attack (although it's usually worded remote compromise) is that the result of a successful attack is the opening of a gateway that can lead to additional compromise or complete takeover of a machine. Given the details you've offered, think this qualifies as "potentially leading to a remote compromise" of a machine. The attack begins when the unsuspecting user clicks on a link to either open an attachment or view a webpage or video. In the background the compromise takes place, after which the malicious software "phones home", downloads additional tools, etc. until the host is completely and utterly compromised. -- Paul Schmehl, Senior Infosec Analyst As if it wasn't already obvious, my opinions are my own and not those of my employer. *** "It is as useless to argue with those who have renounced the use of reason as to administer medication to the dead."

I think we can agree that yes, it is remotely exploitable and as such should be categorized as "remote" in Risk/Impactt scoring systems ? Does anybody disagree ?

I'd be interested to hear your point of view. Hey Thierry - I hope all is well... I'm happy to include "user assisted remote exploitation" as a "remote" vulnerability in academic conversations, but I don't categorize it as "remote" when assessing overall risk to a particular threat in production environments. Like everyone else, my TMs include impact and skill required to exploit a particular vulnerability; but they also include "likelihood of exploitation." While that may sound like a wildcard metric, I quantify it by applying the internal controls in place that may mitigate a particular attack. In "my" networks (networks I control, design, or consult for) most users couldn't execute [common] exploits even if they wanted to. I won't bore you with the controls I deploy as I'm confident you are well aware of the options one has, but the fact they exist at all place "user assisted remote exploits" in a different category for me when assessing risk. When the propensity for a vulnerability to be exploited lies in a particular user's response to any given trigger, as opposed to any authoritative in-place controls to mitigate exposure, then a model's relevant response options are greatly diminished (IMO). As such, I choose to categorize "remote" exploits as those that may be executed against a given host that is autonomously running a [vulnerable] service that can be connected to by some (any) other network client, device, or service for the purposes of ascertaining overall risk. t ___ Full-Disclosure - We believe in it.

If you classify a remote bug (anything that can be exploited remotely) then you are classifying all bugs (you can use a privilege escalation exploit remotely) I agree with Thor, anything that exploits a remote service (HTTP,FTP Etc..) without any user interaction.

A local exploit is one that requires that the attacker first obtain access to the box. For example, you can exploit ls on a Linux box to elevate your privileges, if you can first get on the box through ssh or some other method. I have never seen remote exploit definitions require the limitation of no user action. When discussing taxonomy and the usefulness of vulnerability definitions in real world scenarios, it's much more useful to know that something can be exploited without the attacker having access to the box. Certainly a higher priority is placed on resolving those issues than ones where the attacker first has to obtain access.

Re: [Full-disclosure] When is it valid to claim that a vulnerability leads to a remote attack?
I think the classification system as a whole is ultimately based on agenda. Vendors (I presume) don't want things to sound as bad as they may be. Researchers want things to sound as bad as they CAN be. And the rest of the people would like a means by which to measure "urgency" to patch as it relates to cost/benefit, risk/threat, and potential consequences of inaction. So I think it ultimately comes down to a sliding scale of what the person responsible for incident response is comfortable with. To me, I draw the line of a "remote" exploit to "no user or system interaction required" as I've previously stated. You have to make SOME sort of qualification, or else calculated responses become unmanageable. Analysis beyond that (to me) enters you into a model of diminishing returns. By way of example: If you can send an email exploit to an Outlook client that can execute by a preview only, is that remote? I would say no, as a user would have to preview it. If one could exploit the same vulnerability just by it arriving into one's Outlook inbox without preview would it THEN be remote? Again, I would say no, as Outlook would have to be running. And, of course, one would have to be running Outlook in the first place. As a group, I don't think we need to define what "remote" is. That's up to the response team. What you need to do is decide on what you do when YOU classify something as remote, and then take action according to a predefined plan. That is really the advice I have for the OP. Don't look to what other people consider remote; decide for yourself, and plan a course of action accordingly. t > -Original Message- > From: Paul Schmehl [mailto:pschmehl_li...@tx.rr.com] > Sent: Sunday, October 11, 2009 6:25 PM > To: James Matthews; Thor (Hammer of God) > Cc: full-disclosure@lists.grok.org.uk; valdis.kletni...@vt.edu; > Jonathan Leffler > Subject: Re: [Full-disclosure] When is it valid to claim that a > vulnerability leads to a remote attack? > > --On October 11, 2009 7:18:33 PM -0500 James Matthews > wrote: > > > If you classify a remote bug (anything that can be exploited > remotely) > > then you are classifying all bugs (you can use a privilege escalation > > exploit remotely) I agree with Thor, anything that exploits a remote > > service (HTTP,FTP Etc..) without any user interaction. > > > > My understanding of the classical meaning of "remote exploit" is that > the > machine can be exploited without the attacker needing to have an > account > on the box.
