Re: [Zope] HTTP Request Denial of Service Vulnerability
Yes. We are going through our check database and changing the text of any "Do not use zope because of X" statements we find to "update zope to version X which fixes this issue", which is what it should have been originally. The Foundstone vulnerability management product is intended to help customers fix existing issues in their infrastructure, not to make judgment calls on their choice of deployed software. -Original Message- From: Chris McDonough [mailto:chr...@plope.com] Sent: Friday, July 24, 2009 12:05 PM To: Permeh, Ryan Cc: zope@zope.org Subject: Re: [Zope] HTTP Request Denial of Service Vulnerability Thanks Ryan!

Re: [Zope] HTTP Request Denial of Service Vulnerability
It should be noted that doing this may make it less likely for a general purpose automated scanner like Foundstone (or Nessus or any vulnerability scanner) from finding your deployment, but it does not fix the app from the issue that the scanner was checking for. This may or may not be an appropriate action, depending on your environment. "Good Guy" scanners like our product usually have to try to determine if a site is vulnerable in non-intrusive ways, such as checking banners. Bad guys scanners often send the exploit regardless of version. They have no problem causing damage by sending potentially dangerous inputs to your application. By changing the banner, you may be preventing good guys from seeing the issue and attempting to fix the issue without preventing bad guys from exploiting the issue. In any case, since this was done in 2002, it's unlikely the specific issue in question is very relevant on either side. -Original Message- From: Andreas Jung [mailto:li...@zopyx.com] Sent: Friday, July 24, 2009 10:22 AM To: Permeh, Ryan Cc: zope@zope.org Subject: Re: [Zope] HTTP Request Denial of Service Vulnerability That's why I usually override the Server: HTTP header from within my Zope apps for public sites running on Zope :-) Andreas On 24.07.09 19:15, ryan_per...@mcafee.com wrote: > Ok, the final analysis is as follows: > > We had an incorrect version regex that matched 2.10 the same as 2.1.

Re: [Zope] HTTP Request Denial of Service Vulnerability
Ok, the final analysis is as follows: We had an incorrect version regex that matched 2.10 the same as 2.1. This issue seems to only affect zope version 2.0 through 2.5.01. This lead to the vulnerability showing up with recent versions of zope being scanned. We are fixing both the regex and the suggested fix. The new suggested fix will be to update to the appropriate version of zope (in this case, post 2.5.01), not to replace it with something else. This fix should be updated within the next week or so.

[Zope] HTTP Request Denial of Service Vulnerability
I manage product security at McAfee, of which Foundstone is a part. I am not aware of releasing such an advisory, and am looking into this. Could we get details regarding where this was found? Was this posted to a web site? A security mailing list? And when was it posted? This may have a very different meaning if it was published in 2001 or something like that. Alternately, Foundstone produces a vulnerability management software, was this in a report generated by that product? As far as I know, we try to never make general sweeping statements about products such as those quoted by the poster. Our statements are typically regarding a single vulnerability, and extrapolating to the entire product is not in our nature or in our customer's best interests. We want issues fixed, not to argue about which specific platforms are better than other. Additionally, we try to never release any vague reports such as the one I'd seen. They are typically combined with additional details that would allow one to determine their own risk, and we usually include a CVE number or another common vulnerability identifier. Finally, we follow responsible disclosure, and wouldn't issue an advisory without notifying the vendor prior. I have the appropriate teams trying to track down from an internal standpoint, but any help from the community, especially the original poster, would be appreciated. If our statement or product wording is incorrect, we will certainly rectify this.
