Similiar to MOMBY-1100, this link must be clicked by a victim in order to be effective for an attacker. Unlike MOMBY-1100, however, victims need not be authenticated, which lowers the relative value of the attack; victims are not guaranteed to possess useful session information. On the gripping hand, the attacker does have some freedom to alter the emailAddress parameter in order to further pursuade a victim to click on the presented "return to fix errors" link. For example, the attacker could present a false form for e-mailing Myspace customer service about something compelling, then intentionally alter the user's provided e-mail address with an engineered onSubmit() "hiccup" action immediately before loading the XSS-injected page. Victims, in turn, are more likely to believe the presented "results" does require them to reenter information.
