A while back, Microsoft announced they were moving to release patches on the second Tuesday of each month, lovingly called Patch Tuesday. Soon after, Oracle announced that they too would be moving to scheduled releases of patches on the Tuesday closest to the 15th day of January, April, July and October. Now, Cisco has announced they are moving to scheduled patches on the fourth Wednesday of the month in March and September of each calendar year.
In the attempt to make life easier on administrators and help avoid installing patches every few days, these scheduled releases are now causing organizations to enjoy life between monster patches.
Mar 11 – Microsoft
Mar 26 – Cisco
Apr 8 – Microsoft
Apr 15 – Oracle
May 13 – Microsoft
June 10 – Microsoft
July 8 – Microsoft
July 15 – Oracle
August 12 – Microsoft
September 9 – Microsoft
September 24 – Cisco
October 14 – Microsoft, Oracle
November 11 – Microsoft
December 9 – Microsoft
As you can see, October 14 promises to be a lot of fun for companies running Oracle products on Microsoft systems. While the scheduled dates look safe, I can’t wait until we see the ”perfect storm” of vendor patches.
In a recent discussion on the security metrics mailing list, Pete Lindstrom put forth a rough formula to throw out a number of vulnerabilities that have been discovered versus undiscovered. One of the data points that he cited lead me to his page on “undercover vulnerabilities”, his term for “0-day” in a certain context. Since the term “0-day” has been perverted to mean many things, he clearly defines his term as:
Undercover Vulnerability: A vulnerability that was generally unknown (e.g. not published on any lists, not discussed by “above ground” security folks) until it was actively exploited in the wild. The vulnerability was discovered through evidence of tampering or other means, not through the usual bugfinding ritual.
In my reply challenging some of his numbers, I specifically said that “if we consider that your number 20 is off by at least half, and I would personally guess it’s more like a small fraction, how does this change your numbers?” Pete took this in stride and offered to buy me a case of beer if I could find half a dozen that he didn’t have. Not one to pass up free booze and vulnerability research (yes, i’m weird) I spent several hours Friday doing just that. I ended up with 24 vulnerabilities that seemed to match his definition, roughly half of them in his time frame (“in the last two years”).
Pete’s page got me wondering just how many vulnerabilities classified as ‘undercover’ by his definition. Further, I thought about another question he asked on his page:
I am open to suggestions on an easy way to do this with TypePad (TypeLists, maybe?). Else, I’ll just periodically update as new vulns become available.
I cornered our lead developer Dave and said “make it so” while I mailed Pete asking if OSVDB could help in this effort. As a result, we now have a new classification that we call “Discovered In the Wild” that means the same thing as Pete’s “undercover vulnerability”. I have updated the 20 vulnerabilities listed on his page and added the flag to the ones I researched. This now shows 43 results which is good progress.
Not content with that, I asked a fellow geek who has a world more experience with IDS, NOC management and various devices that would be prone to catching such vulnerabilities “how many do you think were found this way last year”, to which she replied “at least 50”. So vulnerability researchers and OSVDB contributors, it’s up to you to help out! We’re looking for more instances of vulnerabilities being discovered “in the wild”, being exploited and subsequently disclosed (to mail list, vendor, whatever). Please cite your source as best as possible.
To see what we have so far:
- Under “Vulnerability Classification” and “Disclosure”
- Check “Discovered in the Wild”
Thanks to Pete Lindstrom and the Security Metrics mailing list for the input and great idea for a new classification!
Early in 2006, I posted about HP using multiple identifiers for the same vulnerability. Recently, Sun Microsystems has done a little overhaul to their advisory pages and I noticed that they too now use entirely too many tracking numbers.
For example, this Sun advisory has the following:
- Document ID: 200582
- Old Document ID: (formerly 103143)
- Bug ID: 6497289
- SA Document Body: PPGNRLA Internal ID use only.
Why is one tracking number so difficult?
Nutshell What you see here is the output of the ”arfis project”, a simple perl script. It automatically downloads and extract PHP projects from sourceforge.net and checks for Remote File Inclusion vulnerabilities. It then post’s the potential (now it’s -potential-, cause the script is in an early stadium) vuln to this blog.
The idea behind this tool was joked about by several VDB managers over a year ago due to the growing trend of false vulnerability reports popping up in 2006 and 2007. The style of many posts to mail lists were becoming the same, several signatures suggesting a tool or group was involved appeared and it was speculated that many remote file inclusion (RFI) vulnerabilities were the result of a very primitive “grep and gripe” style vulnerability ‘research’. Jump to today and we have this script doing what we suspected all along. Some will proclaim “genious!” and others may be quick to download and taste the fame of being a “vulnerability researcher”. Before you plan your victory party and brush up your resume to include vulnerability research, consider that this script is blindly searching projects for specific lines that suggest an application is vulnerable to RFI. Without looking at the source code manually, there is no way to accurately determine if it is a legitimate vulnerability or a false positive. The people using this script don’t seem to fully understand that and blindly use the tool w/o consideration.
Recently, 8 or so of these arfis-found vulnerabilities were reported to milw0rm for inclusion in their database. Upon examination, 6 of the 8 were not legitimate vulnerabilities. Of the 2 that were, one had been reported two years prior. This is a good indication of how trustworthy the tool is, early release or not, and what kind of burden it places on VDBs who do their best to vet vulnerability disclosures to a limited degree.
Yes yes, yet another “Month of..” campaign. If you track the mail lists, you may have seen a post about a “Month of [something]” Bugs. Despite little follow-up, this campaign is going strong on the 17th day demonstrating a variety of vulnerabilities in lycos.com, search.myway.com, images.google.com, mamma.com, metacrawler.com, ezilon.com, ask.com, ftpsearch.rambler.ru, searcheurope.com, blogs.yandex.ru, clusty.com, autos.msn.com, shopping.msn.com, gigablast.com, hotbot.com, search.yahoo.com and meta.ua.
Definitely an interesting project to follow.
A while back I wrote about VDBs and site specific vulnerabilities. The general concensus is that VDBs should not track site specific vulnerabilities, even though some do for bigger sites that provide services (i.e. Google, Gmail, Yahoo). While OSVDB does not, we recently ran across a site that is now tracking Cross-Site Scripting (XSS) vulnerabilities in web sites. Interesting watching various high profile sites that don’t appear to properly test their applications before deployment.
It was bound to happen, now we get to see a Month of Search Engine Bugs. It would be nice if this effort included some bugs with meat rather than relatively obscure cross-site scripting issues.
The time has come for announcement of my new project – Month of Search Engines Bugs. This project will be in the next month. So June is a month of bugs in search engines. Purpose of this Month of Bugs is a demonstration of real state with security in search engines, which are the most popular sites in Internet. To let users of search engines and web community as a whole to understand all risks, which search engines bring to them. And also to draw attention of search engines~R owners to security issues of their sites. During the month everyday will be publish vulnerabilities in most popular search engines of the world. Cross-Site Scripting vulnerabilities in particular. Everyday will be publish vulnerabilities in different engines (minimum one publication at a time, but there will be bonus publications also).
I saw this article the other day, IBM Scolds TippingPoint Over Hacking Contest and figured now what? But I decided it would be an interesting read.
A couple quick blurbs from the article:
IBM’s ISS division has torn into rival TippingPoint for sponsoring the hacking contest that led to the disclosure of a QuickTime vulnerability in Apple’s Safari browser. “IBM Internet Security Systems agrees with Gartner’s assessment that “public vulnerability research and ‘hacking contests’ are risky endeavors, and can run contrary to responsible disclosure practices.” It is for this reason that IBM ISS strongly adheres to its well-established responsible disclosure guidelines.”
Once I read the article it was then that I realized…. that it really wasn’t IBM, but ISS (who IBM purchased recently) that was scolding TippingPoint for sponsoring this contest. Immediately I thought about all the drama that went on when ISS disclosed their Apache Chunked Encoding Overflow back in 2002.
http://lwn.net/Articles/2756/ It all looks like a fairly normal response to security problems in the free software community, until you look a little more closely. It turns out that the Apache group was already aware of the problem and was working on a fix. The Computer Emergency Response Team (CERT) also was already involved. It also turns out that the ISS patch does not completely fix the problem. ISS, in its hurry to publicise the vulnerability, had not checked with either CERT or the Apache Software Foundation.
Does anyone remember all of this?
ISS took quite a bit of criticism for this disclosure and responded publicly to clean up any confusion and misunderstanding.
The very last portion of this posting is what I find real interesting:
ISS has made these decisions based on our mission to provide the best security to our customers and being a trusted security advisor.
For me personally.. It is kind of funny that disclosure almost always seems to come back to the argument of… we did it for the greater good… we did it for the benefit of others… we did it for the right reasons…
But you on the other hand…
In the final days of March, a “week of Vista bugs” was announced. As some suspected, it turned out to be a hoax. For the full story on how it was carried out, check the breakdown from the perpetrators.
All in all, not a very impressive hoax by any means. Even looking at the screenshot they include of Google, you can see that the top ten hits weren’t anyone seriously buying into it.
