Breach in j.b.i. @ y.i

Analysis

Initial report: one defaced page http://vserverX/eshare/catalog redirecting to http: // www . test . we-create . org 

Note that if redirection works apparently with IE it didn't work with iceweasel, I could just see the attempt of redirection in the source of the page: 
<script> window.location=\"http: // www . test . we-create . org/\"; </script>

# On host: 
apt-get install tct sleuthkit

# Isolate the vserverX
iptables -I INPUT -d <ip_of_vserverX> -j DROP

# Grep mactimes before touching the system
grave-robber -o LINUX2 -c /path/to/vserverX/ -b ./vserverX -m 
# mactime from one week ago till now
mactime -b vserverX -p /path/to/vserverX/etc/passwd mm/dd/yyyy |tee vserverX.mactime
# apparently mactime could work directly on live system with -d ...

# Search string we-create in /var/www and /var/lib/mysql:
/var/lib/mysql/oscommerce/configuration.MYD

# Extract corresponding sql table:
vserverX:/# mysqldump -uuserX -p  --opt oscommerce > oscommerce.sql

# Analyse sql dump:
INSERT INTO `configuration` VALUES (1,'Store Name','STORE_NAME','<script> window.location=\"http: // www . test . we-create . org/\"; </script>','The name of my store',1,1,'2007-05-11 21:04:30','2006-12-22 09:32:15',NULL,NULL)...

# This is the modification apparent on the defaced page, done at '2007-05-11 21:04:30'
# note that there were other defacing attempts here:
INSERT INTO `categories_description` VALUES (...
   ,(25,4,'<script> window.location=\"http:/')                                                                                                                               
   ,(25,2,'<script> window.location=\"http:/')

Conclusions

  • Initial breach
    • attack came from 85.105.88.202 = dsl.static.85-105-22730.ttnet.net.tr (Turkish ADSL)
    • this site was found initially by a simple google search (Google Turkey!) for "catalog/admin/backup.php"
      easy was to find unprotected oscommerce websites...
      I visit another one from the Google list: http: // oscommerce . uksz . net/catalog/admin/
      and surprise, Store Name = window.location="http: // www . test . we-create . org/";
      no comment!
    • eshare was defaced via eshop, simply both were sharing the same DB
  • Counter-measures
    • Protect access to catalog/admin
      This was done but only for https, default conf with Apache was still AllowOverride None for http connections
