Top vulnerability researcher?

Posted by jkouns Sat, 24 May 2008 20:16:53 GMT

Who is the top vulnerability researcher? Who has discovered the most computer security vulnerabilities? Which country has the most researchers and publishes the most vulnerabilities? Who has discovered the most critical vulnerabilities?

From looking at OSVDB here are the top 12 researchers in terms of volume:

Rank    Creditee        # Vulns
-----------------------------------------
1)      r0t         770
2)  Lostmon Lords       241
3)      rgod            239
4)      Aliaksandr Hartsuyeu    201
5)      Kacper          199
6)      James Bercegay      180
7)      luny            142
8)      Diabolic Crab       139
9)      Janek Vind "waraxe" 136
10)     JeiAr           117
11)     Dedi Dwianto        86
12)     M.Hasran Addahroni  79

Take a look at the other OSVDB Browse categories and note you can even click on a Creditee’s name and see all of the vulnerabilities that they have discovered here: http://osvdb.org/browse

Of course our statistics are based off of the content in OSVDB and we need your help to provide better statistics. If you are a researcher, it would help if you could take the time to create an OSVDB account and update the vulnerabilities that you have discovered!

You can signup for an OSVDB account here: https://osvdb.org/account/signup

Here is a quick overview:

-Search for your vulnerabilities at http://osvdb.org/search/advsearch -Click on your vuln, then click “Edit Vulnerability” -Click the Credits menu item, if credit is missing click “Toggle Add Author…” -You name may already be in the database, as you type it will search OSVDB to see if your information is there. If so, select and click “Add Author”. -Once you add the creditee information you can update your information or if your name is not there you can add it as a new creditee.

Rinse and repeat!

Vulnerability counts and OSVDB advocacy

Posted by jericho Thu, 03 Apr 2008 21:42:39 GMT

CVE just announced reaching 30,000 identifiers which is a pretty scary thing. CVE staff have a good eye for catching vulnerabilities from sources away from the mainstream (e.g. bugtraq) and they have the advantage of being a very widely accepted standard for tracking vulnerabilities. As companies and researchers request CVE numbers for disclosures, they get a lot of the information handed to them on a silver platter. Of course, sometimes that platter is full of mud and confusion as vendors don’t always provide clear details to help CVE accurately track and distinguish between multiple vulnerabilities. I’ve also pointed out many times in the past that CVE is a very unique VDB that provides identifiers for vulnerability tracking. They do not provide many fields associated with other VDBs (solution, creditee, etc). As such, they may have a single entry that covers multiple distinct vulnerabilities if they are the same class (XSS, SQLi, RFI), or if there is a lack of details but they know it affects the same product (Oracle). So when we see 30,000 identifiers, we have to realize that the real count of vulnerabilities is significantly higher.

CVE is run by The MITRE Corporation, sponsored / funded by the NCSD (US-CERT) of DHS under government contract. That means our tax dollars fund this database so it should be of particular interest to U.S. taxpayers in the security industry. I know from past discussions with CVE staff and other industry veterans that on any given day, they are more likely to have more work than available staff. That means the rate of vulnerabilities that get published is greater than the resources CVE can maintain to track them. In short, the 30,000 identifiers you see only represents a percentage of the vulnerabilities actually disclosed. We could probably debate what percentage that represents all day long, and I don’t think that is really the point here other than “we know it isn’t all of them”.

Every VDB suffers from the same thing. “Commercial” VDBs like X-Force, BID and Secunia have a full time staff that maintain their databases, like CVE does. Despite having all of these teams (some of them consisting of 10 or more people) maintain VDBs, we still see countless vulnerabilities that are ‘missed’ by all of them. This is not a slight against them in any way; it is a simple manner of resources available and the amount of information out there. Even with a large team sorting disclosed vulnerabilities, some teams spend time validating the findings before adding them to the database (Secunia), which is an incredible benefit for their customers. There is also a long standing parasitic nature to VDBs, with each of them watching the others as best they can, to help ensure they are tracking all the vulnerabilities they can. For example, OSVDB keeps a close eye on Secunia and CVE specifically, and as time permits we look to X-Force, BID, SecurityTracker and others. Each VDB tends to have some researchers that exclusively disclose vulnerabilities directly to the VDB of their choice. So each one I mention above will get word of vulnerabilities that the rest really have no way of knowing about short of watching each other like this. This VDB inbreeding (I will explain the choice of word some other time) is an accepted practice and I have touched on this in the past (CanSecWest 2005).

Due to the inbreeding and OSVDB’s ability to watch other resources, it occasionally frees up our moderators to go looking for more vulnerability information that wasn’t published in the mainstream. This usually involves grueling crawls through vendor knowledge-bases, mind-numbing changelogs, searching CVS type repositories and more. That leads to the point of this lengthy post. In doing this research, we begin to see how many more vulnerabilities are out there in the software we use, that escapes the VDBs most of the time. Only now, after four years and getting an incredible developer to make many aspects of the OSVDB wish-list a reality, do we finally begin to see all of this. As I have whined about for those four years, VDBs need to evolve and move beyond this purely “mainstream reactionary” model. Meaning, we have to stop watching the half dozen usual spots for new vulnerability information, creating our entries, rinsing and repeating. There is a lot more information out there just waiting to be read and added.

In the past few weeks, largely due to the ability to free up time due to the VDB inbreeding mentioned above, we’ve been able to dig into a few products more thoroughly. These examples are not meant to pick on any product / VDB or imply anything other than what is said above. In fact, this type of research is only possible because the other VDBs are doing a good job tracking the mainstream sources, and because some vendors publish full changelogs and don’t try to hide security related fixes. Kudos to all of them.

Example: Search your favorite VDB for ”inspircd”, a popular multi-platform IRC daemon. Compare the results of BID, Secunia, X-Force, SecurityTracker and CVE. Compare these results to OSVDB after digging into their changelogs. Do these same searches for “xfce” (10 OSVDB, 5 max elsewhere), “safesquid” (6 OSVDB, 1 max elsewhere), “beehive forum” (27 OSVDB, 8 max elsewhere) and “jetty” (25 OSVDB, 12 max elsewhere). Let me emphasize, I did not specifically hand pick these examples to put down any VDB, these are some of the products we’ve investigated in the last few weeks.

The real point here is that no matter what vulnerability disclosure statistic you read, regardless of which VDB it uses (including OSVDB), consider that the real number of vulnerabilities disclosed is likely much higher than any of us know or have documented. As always, if you see vulnerabilities in a vendor KB or changelog, and can’t find it in your favorite VDB, let them know. We all maintain e-mail addresses for submissions and we all strive to be as complete as possible.

2007 Top Vulnerable Vendors?

Posted by jericho Wed, 19 Sep 2007 13:45:13 GMT

http://www.eweek.com/article2/0,1895,2184206,00.asp

New IBM research shows that five vendors are responsible for 12.6 percent of all disclosed vulnerabilities. Not surprising: In the first half of 2007, Microsoft was the top vendor when it came to publicly disclosed vulnerabilities. Likely surprising to some: Apple got second place. IBM Internet Security Systems’ X-Force R&D team released its 2007 report on cyber attacks on Sept. 17, revealing that the top five vulnerable vendors accounted for 12.6 of all disclosed vulnerabilities in the first half of the yearor 411 of 3,272 vulnerabilities disclosed. Here’s the order in which the top 10 vendors stacked up, by percentage of vulnerabilities publicly disclosed in the first half of the year: Microsoft, 4.2 percent Apple, 3 percent Oracle, 2 percent Cisco Systems, 1.9 percent Sun Microsystems, 1.5 percent IBM, 1.3 percent Mozilla, 1.3 percent XOOPS, 1.2 percent BEA, 1.1 percent Linux kernel, 0.9 percent

This article was posted to ISN the other day and struck a nerve. How many times are we going to see vulnerability statistics presented without qualification? Rather than really get into the details, I replied with a single simple example on why such statistics are misleading at best and incorrect at worst. The bulk of my reply follows. My hopes for Lisa or IBM/ISS clarifying this is already dwindling.

One other factor, that Lisa Vaas apparently didn’t ask about, is how ISS X-Force catalogs vulnerabilities, and if their method and standards could impact these numbers at all. Take for example, two X-Force vulnerability database entries: Oracle Critical Patch Update - July 2007 http://xforce.iss.net/xforce/xfdb/35490 18 CVE, 30+ Oracle Oracle Critical Patch Update - January 2007 http://xforce.iss.net/xforce/xfdb/31541 30 CVE, 50+ Oracle So when comparing numbers, you have 2 X-Force entries that equate to 48 CVE entries that equate to *more than 80* unique and distinct vulnerabilities according to Oracle. I’m not a math or stat guy, but I have a feeling that this could seriously skew the statistics above, especially when you consider that Microsoft and Apple both have a more distinct breakdown and separation in the X-Force database. Anyone from IBM/ISS care to clarify? Lisa, did you have more extensive notes on this aspect that didn’t make it in the article perhaps?

Scrubbing the Source Data

Posted by jericho Mon, 16 Jul 2007 05:56:40 GMT

A few months ago, Jeff Jones at CSO Online blogged about “Scrubbing the Source Data”, talking about the challenges of using vulnerability data for analysis. Part 1 examined using the National Vulnerability Database (NVD) showing how you can’t blindly rely on the data from VDBs. In his examples he shows that using the data to examine Windows is probably fairly accurate, yet examining Apple is less so and Ubuntu Linux is basically not possible. Unfortunately, there isn’t a part two to the series (yet) as implied by the title and introduction. Jones concludes the post:

Given these accuracy levels for vulnerabilities after the vendor has acknowledged it and provided a fix, it doesn’t seem like too much of a stretch to also conclude that using this data to analyze unpatched data would be equally challenging. Finally, I think this exercise helps demonstrate that anyone leveraging public data sources needs to have a good understanding of both the strengths and the weaknesses that any given data source may have, with respect to what one is trying to analyze or measure, and include steps in their methodology that accomodates accordingly.

OS Security, Old Debate, New Info

Posted by jericho Thu, 29 Mar 2007 18:42:21 GMT

Check out this article/report by OmniNerd, which tested various operating systems for security. They performed a base line vulnerability scan during installation, after installation and after patches had been applied. Each installation was done to mimick as close to a ‘default install’ by clicking ‘next’ when possible. While one can argue various points of this test, they did a good job defining the operating system, configuration and resulting open ports, along with corresponding vulnerabilities. The only questions that immediately come to mind are if the Solaris install included Update 3 and why they didn’t have any charts or graphs summarizing the information.

This is hands down one of the most fair and unbiased tests I have seen in a while, based on the information in the article.

Microsoft patches 133 Critical/Important Vulns in 2006

Posted by jericho Wed, 13 Dec 2006 13:56:59 GMT

http://www.avertlabs.com/research/blog/?p=153

McAfee is reporting that Microsoft patched 133 Critical / Important vulnerabilities in 2006. They also compare this number against previous years to presumably demonstrate that security isn’t getting better at Microsoft.

Oracle RDBMS vs Microsoft SQL Server

Posted by jericho Tue, 21 Nov 2006 04:51:29 GMT

http://www.databasesecurity.com/dbsec/comparison.pdf

Introduction This paper will examine the differences between the security posture of Microsoft’s SQL Server and Oracle’s RDBMS based upon flaws reported by external security researchers and since fixed by the vendor in question. Only flaws affecting the database server software itself have been considered in compiling this data so issues that affect, for example, Oracle Application Server have not been included. The sources of information used whilst compiling the data that forms the basis of this document include: The Microsoft Security Bulletins web page The Oracle Security Alerts web page The CVE website at Mitre. The SecurityFocus.com website A general comparison is made covering Oracle 8, 9 and 10 against SQL Server 7, 2000 and 2005. The vendors’ flagship database servers are then compared. [..]

Vulnerability Type Distributions in CVE

Posted by jericho Wed, 04 Oct 2006 23:33:05 GMT

http://cwe.mitre.org/documents/vuln-trends.html Document version: 1.0 Date: October 4, 2006

For the past 5 years, CVE has been tracking the types of errors that lead to publicly reported vulnerabilities, and periodically reporting trends on a limited scale. In support of the Common Weakness Enumeration (CWE) project, and as a result of the interest in this work as mentioned during the “Year of the web application: Hack & Data from the Front lines” panel at the 5th Annual Cyber Security Executive Summit in New York City on September 13, 2006, we have published a more extensive analysis. An updated version will be released once 2006 is complete.

The primary goal of this study is to better understand research trends using publicly reported vulnerabilities. It should be noted that the data is obtained from an uncontrolled population, i.e., decentralized public reports from a research community with diverse goals and interests, with an equally diverse set of vendors and developers. More specialized, exhaustive, and repeatable methods could be devised to evaluate software security. But until such methods reach maturity and widespread acceptance, the overall state of software security can be viewed through the lens of public reports.

Vulnerability Research In Numbers

Posted by jericho Mon, 28 Aug 2006 05:33:50 GMT

I’m so far behind in my daily routine and missed Thomas Ptacek’s post on Vuln Research In Numbers. Fortunately, Dave Aitel referenced the blog entry which prompted me to check it out. I so desperately want Ptacek to run his numbers against a complete OSVDB data set, but alas, I know that we do not have a complete data set for 2004. Symantec’s BID database has some problems with consistancy, citing sources (aka provenance) and missing vulnerabilities (which plagues most VDBs to one degree or another). In my mind, OSVDB tends to be more complete than most VDBs and maintains a creditee field, but due to a lack of volunteers we just don’t have enough entries public for him to do the same generation of statistics. Some day maybe! Until then, this is a very neat post with a different slant.

Depending on how you count flaws..

Posted by jericho Mon, 13 Mar 2006 03:15:01 GMT

After flap, Symantec adjusts browser bug count
Depending on how you count flaws, either IE or Firefox could be considered less secure
News Story by Robert McMillan

MARCH 07, 2006 (IDG NEWS SERVICE) - A report issued today by Symantec Corp. seeks to satisfy users of both Mozilla Corp.’s Firefox browser and Microsoft Corp.’s Internet Explorer.

In its latest Internet Security Threat Report, covering the last six months of 2005, the company now features two different ways of counting browser bugs: one that finds that Internet Explorer has the most vulnerabilities, and a second that reveals Firefox as the bug leader.

Thank you Symantec, for generating completely useless vulnerability statistics. When you can manipulate them to support either side of an argument (and do so intentionally), what’s the point? Just define your criteria for counting a vulnerability, define your time frame, and let the results speak for themselves.
