I was browsing the web for possible security issues with my website, and I was shocked at what I found. I was able to login to administrator accounts without knowing username and login information, and do anything I wanted within my site.
I typed the following into the URL:
javascript:alert(document.
I store user login information in the cookie by using login=USER_ID
I then typed in:
javascript:void(document.c
This gave me access to my entire site!
So my question is....how do I prevent this? I'm assuming I'll have to recode how my site determines when a user is logged in.

Thanks Blaz, but I need the users to stay logged in for up to 2 weeks at a time. I thought sessions were only temporary and go away after the user closes the browser, thus having to login every time. Is there a way to make them last longer or do I need to store a cookie that will create a new session somehow? Thanks for the help. (I'm coding in PHP by the way)
You could code something similar to sessions yourself.
Every time the user logs in create a unique ID (long) 6666666-7777777-888888888-
If you find a match you get the user ID from the database.
Update access time everytime you check the login ID (probably on every page)
Delete records where last access time > 2 weeks.

Use session for "login" variable instead of a cookie. The user does not have access to session variables.
