Title: Apple Safari Cross-Domain Dialog Box Spoofing Vulnerability
Severity: MODERATE
Description:
Apple Safari is reported prone to a cross-domain dialog box spoofing vulnerability. This issue may allow a remote attacker to carry out phishing style attacks.
Reportedly, the vulnerability presents itself as dialog boxes from inactive windows may appear in other windows. It is reported that an attacker can exploit this issue by creating a malicious Web site and enticing a user to follow a link to the site. If the user follows the link, the attacker can then trigger this issue by somehow enticing a user to follow another link to a trusted site in a new window. The attacker can then display a spoofed dialog box to the user that seemingly comes from the trusted site. Typically this dialog box would mimic the legitimate site.
An attacker may exploit this vulnerability to spoof an interface of a trusted web site. This vulnerability may aid in phishing style attacks.
It should be noted that to aid in this attack an attacker may implement the JavaScript 'target' attribute in a link or form to keep an old window open. It is conjectured that this issue may allow for exploitation through browser tabs as well as windows.
Apple Safari 1.2.3 (v125.9) is reported vulnerable to this issue. It is likely that other versions are affected as well.
