It looks like a session fixation vulnerability (if this is the right
terminology):

| Internal Defect: 45186
| 
| Symptom: When a user logs in using forms authentication, they receive
| a cookie and a login page. The user logs in and obtains a
| credential. A security vulnerability exists where an attacker could
| send his unauthenticated cookie to person X. If person X logged in
| using this cookie, the attacker could hijack the seesion of person X
