Security researcher Aviv Raff has revealed the vulnerability in his blog. By creating a specially crafted URL, and sending it via an e-mail, an attacker can convince the user that the spoofed URL, shown in the mail application, is from a trusted domain, such as a bank, PayPal or a social network.
When clicking on the URL, the Safari browser will be opened. The spoofed URL, shown in the address bar of the Safari browser, will still be viewed by the victim as if it is from a trusted domain.
iPhone Mail and Safari on firmware 1.1.4 and 2.0 are affected by this vulnerability. Earlier versions may also be affected, said Raff.
Raff is currently withholding the technical details of the vulnerability until a fix is delivered by Apple.
He said Apple has acknowledged the vulnerability in the Mail application, and is still investigating the issue in the Safari for iPhone browser.
