Cross Site Request Forgery (CSRF)

Abbreviation(s) and Synonym(s):

None

Definition(s):

  An attack in which a Subscriber who is currently authenticated to an RP and connected through a secure session, browses to an Attacker’s website which causes the Subscriber to unknowingly invoke unwanted actions at the RP. For example, if a bank website is vulnerable to a CSRF attack, it may be possible for a Subscriber to unintentionally authorize a large money transfer, merely by viewing a malicious link in a webmail message while a connection to the bank is open in another browser window.
