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='
