ZH2005-13SA (security advisory): NEXTWEB (i)Site™ multiple vulnerabilities
Published: 1 June 2005 - GOOD MONTH EVERYBODY ;-)

Released: 1 June 2005

Name: (i)Site™ 

Affected Versions: ALL

Issue: SQL injections, exception handling, unsafe directories

Author: Trash-80 - dpangalos@...e-h.org

Vendor: http://www.nextweb.gr & http://www.isite.gr

Description

***********

Zone-H Security Team has discovered multiple vulnerabilities in (i)Site website management system. An expensive web application with high-profiled customers. Unsafe directories, SQL injection vulnerabilities, failures to validate user inputs and to handle exceptional conditions were found in (i)Site.

Details

******* 

1. SQL injection in login.asp

You are able to bypass the authentication process by sending a crafted
username and password that changes the SQL query in login.asp and thus
grants you with access to the administration of (i)Site.

e.g. www.victim.com/admin/login.asp
usename: attacker
password: ' or 'a'='a

2. Databases are not located in a safe directory. Remote scanners used for malicious intends are checking for unsafe database directories. Locating the databases out of the webroot is a good solution. Thus, downloading Users.mdb file discloses me the administrator's username and password.

e.g www.victim.com/databases/Users.mdb

3. Failure to handle exceptional conditions and validating user inputs. The following will cause an error 500 for a few minutes.

e.g. www.victim.com/isite/page/*.asp?mu=&cmu='

Solution:

*********

Vendor has been contacted on May 24th.
Since then, vendor did not reply to a series of e-mails informing him about the vulnerabilities in (i)Site.
