Modsecurity

Mar 18, 2007

I recently leased a dedicated server and it has somethign called modsecurity installed and I "think" it is causing me a slight problem. I installed Tikiwiki (using FANTASTICO as teh installer) to put a wiki on my site. Problem: When I edit a page and hit "Save." I get "FOBIDDEN you do not have permission to access /tiki/tiki-editpage.php on this server". After playing around with it all day, I finally asked my server management folks if they could figure out the issue and they said it looked like a "modsecurity" issue. If I understand correctly, modsecurity will clocu URLs that have certain characteristics.

my questions are:

1) How can I determine exactly which modsecurity rule is being violated and

2) How can I remove just taht rule so that things will work with the wiki program?

ModSecurity

Nov 30, 2007

I have a site on my server that is running a Flash splash-page and ModSecurity keeps getting tripped when anyone accesses the page.

I am running the default configuration supplied by CPanel 11. The rule that is getting tripped is the XSS rule.

Here is some more info:

Code:
Pattern match "(?:(?:on(?:(?:mo(?:use(?:o(?:ver|ut)|down|move|up)|ve)|key(?:press|down|up)|c(?:hange|lick)|s(?:elec|ubmi)t|(?:un)?load|dragdrop|resize|focus|blur)W*?=|abort)|(?:l(?:owsrcW*?(?:(?:java|vb)script|shell)|ivescript)|(?:href|url)W*? ..." at ARGS:texts. [id "950004"] [msg "Cross-site Scripting (XSS) Attack. Matched signature <src="http:>"] [severity "CRITICAL"]

ModSecurity Log - Googlebot?

Oct 3, 2006

Upon reviewing my modsecurity log today, I found an interesting hit from google.

-------------------

Requesting IP: 66.249.65.67 is http://ws.arin.net/cgi-bin/whois.pl?...t=66.249.65.67

Date: 2006-10-03

Time: 07:10:16

Handler: mod_gzip_handler

Get: /page/index/1&show=25,07,2005?php%20echo%20$bmc_vars%5B'site_url'%5D;%20?%3E/profile.php?id=1

Mod_Security-Message: Access denied with code 406. Pattern match "echo " at THE_REQUEST

Mod_Security-Action: 406

------------

The rule that set off this 406 response was:

SecFilterSelective THE_REQUEST "echo "

What I find interesting is that I do not have any such URL structure on this website that google requested.

ModSecurity: Access Denied With Code 400 (phase 2)

Oct 17, 2007

We have a small Hosting reseller account at eNom. We have a new customer that moved his website from another hosting company to ours. The website is on a shared IP. Enom also uses a internal IP for internal use associated to the domain.

The problem we have is that AOL users can not see the website. As far as we can tell no other ISP's are having this problem. Everyone can see it except AOL users.

When AOL users go to the site they get "Page can not be found". After several calls to eNom support and them triple checking the DNS we still have the problem.

I looked at the error log for the website this morning. I found several errors. I looked up the IP's with the errors and they all pointed back to AOL.. See below for two examples of the errors....

Is this a server problem or DNS?

What do these errors mean and what do I do about it?

The domain is http://2hotlicks.com . They sell Hot Sauce.. Would AOL block it because of the keywords in the Domain name?

Modsecurity Clamav Upload Scanning Doesn't Work
