Re: [Zope] HTTP Request Denial of Service Vulnerability

[TsungWei Hu]

Thanks.

The vulnerability report was originally generated by 'Foundstone Enterprise'
product on July 2. I was told the license for this product expired that now
I can not know the exact product version. Anyway, glad to see this fixed.

Re: [Zope] HTTP Request Denial of Service Vulnerability

[Ryan_Permeh]

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.

Re: [Zope] HTTP Request Denial of Service Vulnerability

[Ryan_Permeh]

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.

Re: [Zope] HTTP Request Denial of Service Vulnerability

[Ryan_Permeh]

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.

If you have any further questions pertaining to McAfee (or Foundstone) security 
reports, please feel free to contact me directly, or via secur...@mcafee.com.  
I am not a full time member of this list, so I may not see any replies or 
questions made only to the list.

Subject: RE: [Zope] HTTP Request Denial of Service Vulnerability

It is not related the specified hotfix.  I'm getting details now, but this is 
how it seems:
1. this is from the Foundstone product, not a public advisory.  The Foundstone 
product is a vulnerability scanner, and it seems that it feels that the 
original poster's site is vulnerable to the stated issue.
2. The vulnerability check was written and published in 2002.  
3. I am looking into details regarding both what the details of this issue 
originally were, and what we look for to trigger it's existence.

This leads to a couple observations.

1.  This is likely a false positive, unless the original poster was running 
ridiculously old software.  
2. We will fix the check logic or remove the check entirely.  Checks this old 
rarely add much value to the product
3. In any case, if the check stays, we will update the text.  I'm not sure who 
wrote the original text in 2002, but it obviously doesn't apply now.

[Zope] HTTP Request Denial of Service Vulnerability

[Ryan_Permeh]

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.

TsungWei, with respect but you are telling barely nonsense. The
mentioned issue only affected
sites where managers gave ZMI access to untrusted users. So this issue
is of limited importance.
In addition it has been fixed within less than one day (compare this to
other systems).
In addition: Zope is an application server, not a CMS. Also: compare the
number of critical
bugs within Zope to other systems.

ZOPE IS VERY SECURE.

So please stop with such postings spreading FUD and containing improper

It might be premature to blame this on Foundstone.  I can't seem to  
find this security advisory online at all.  No advisory id was  
included nor any reference at all and the recommendation doesn't look  
at all like what usually comes from a legit advisory.  I smeil a fake.

Re: [Zope] HTTP Request Denial of Service Vulnerability

[Chris McDonough]

I just sent the below via http://www.foundstone.com/us/contact-form.aspx .  I'd 
suggest that others do the same; this company is totally wrong about this 
conclusion...

You recently issued a security warning to the effect:

"""
= Name =

Zope HTTP Request Denial of Service Vulnerability

= Description =

A vulnerability in Zope may allow a remote attacker to manually shutdown the 
system.

= Observation =

The Zope Web Content Management system has been identified with a critical 
denial of service vulnerability. A malicious attacker could manually shutdown 
the target system remotely via a custom web HTTP field request. This 
vulnerability is especially dangerous as the "kill" packet can be completely 
forged thereby increasing the difficulty when tracking would be intruders and 
attackers.

= Recommendation =

Although the Zope development environment is one of the largest and most widely 
supported open source web content management solutions, it has been plagued 
with 
exploitable vulnerabilities. Due to the nature of the software and shear number 
of vulnerabilities, Foundstone Labs recommends you consider utilizing a 
different content management solution and at a minimum upgrade your software. 
Zope updates can be freely downloaded from www.zope.org
"""

Your conclusion here is wrong.  This particular "vulnerability" is for Zope 
installations who offer the ability for *untrusted users* to add code through 
the web.  This is not the default setup; a user needs to explicitly enable such 
a setup. The conclusion is akin to saying that people should not use Zope 
because they might do something bad to Zope if they have access to the 
administrative interface.  This is the case with *any* application server or 
content management system.

I'd suggest getting a little more knowledge about your material before scaring 
folks.  The Zope folks do full-disclosure of all vulnerabilities; it's up to 
you 
to discern the "scary" ones from the "ho hum" ones. This is definitely a ho-hum 
one, and in no way deserves this conclusion.

Re: [Zope] HTTP Request Denial of Service Vulnerability

[Chris McDonough]

I have no idea who "Foundstone Labs" is, nor if the denial of service 
vulnerability they're talking about is indeed the one fixed by 
http://www.zope.org/advisories/advisory-2008-08-12/ but:

a) if it is, if you read it closely, you'll note that it's for Zope instances 
where untrusted users have unrestricted access to the ZMI and the ability to 
add 
Python Scripts.  Do you have such a setup?

b) Zope has historically been *very* secure; this company is utterly, 
completely, and hopelessly clueless (nor can they spell "sheer").  If you want 
*real* security horror, I'd suggest taking their advice and "upgrading" to any 
PHP based solution. ;-)

[Zope] HTTP Request Denial of Service Vulnerability

[TsungWei Hu]

I have a Plone 3.2.3 site that runs with Zope 2.10.8 and receive a security
notice as follows. Is it sufficient to fix this just installing
http://www.zope.org/Products/Zope/Hotfix-2008-08-12 ? Thanks, /marr/

= Name =

Zope HTTP Request Denial of Service Vulnerability

= Description =

A vulnerability in Zope may allow a remote attacker to manually shutdown the
system.

= Observation =

The Zope Web Content Management system has been identified with a critical
denial of service vulnerability. A malicious attacker could manually
shutdown the target system remotely via a custom web HTTP field request.
This vulnerability is especially dangerous as the "kill" packet can be
completely forged thereby increasing the difficulty when tracking would be
intruders and attackers.

= Recommendation =

Although the Zope development environment is one of the largest and most
widely supported open source web content management solutions, it has been
plagued with exploitable vulnerabilities. Due to the nature of the software
and shear number of vulnerabilities, Foundstone Labs recommends you consider
utilizing a different content management solution and at a minimum upgrade
