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& "'"
