	Injection

Just as a note, you can also use their normal domain instead of rp4me.com.
i.e. jetblue.eresourceplanner.com works in addition to jetblue.rp4me.com.

Do you know if the passwords are hashed/salted in the database? Or are they
all plaintext? This looks like it could become huge overnight. Especially
since hsn.eresourceplanner.com was one of the first subdomains I saw (it
has to be home shopping network, right?).

cough cough

Also, it appears to be every page (FirstTimeLogin.asp,
Forgot.asp, PasswordRetrieval.asp) and not just the main login.asp file.

You're right though, hopefully this gets their attention.
