This should prevent access to all FTP URLs. for older devices with no available patch) would be to deny all traffic to the public internet and configure the device to use a HTTP proxy located in the internal network. Such server can run on any TCP/IP port number. The attacker has to set up an FTP server or use an existing public one.

The following versions were tested and found vulnerable:Įarlier versions weren’t available for testing, but according to available statistics their usage should be negligible. Safari allows (over)writing of HttpOnly cookies so the flag doesn’t prevent this vulnerability to be exploited for session fixation and similar attacks.Ĭookies with the Secure flag aren’t accessible for documents loaded via FTP. Earlier versions would be vulnerable even with the HttpOnly flag. Support for this flag reportedly appeared in Safari 4. The cookie attack requires JavaScript so existing cookies with the HttpOnly flag can’t be seen by the attacker. The attack can be performed on normal web pages by embedding an IFRAME pointing to an FTP URL.

password autofilling and geolocation permissions.
It’s possible that cookies aren’t the only resource accessible this way, but at least recent Safari versions (tested desktop only) use the document origin instead of only host or domain for most other access control, e.g. The attacker-supplied document, exploit.html, can therefore access and modify cookies belonging to via JavaScript. Yet the document properties such as document.domain and okie are correctly initialised using. However, when loaded by a vulnerable browser, the network layer uses an extraneously decoded version of the document would be loaded from, not. These URLs can be of the form The problem arises when encoded special characters are used in the user or password parts.Ĭonsider the following correctly interpreted, the URL refers to a document on. Safari supports the FTP URL scheme allowing HTML documents to be accessed via URLs beginning with “ftp://”. The HttpOnly and Secure cookie flags represent an important mitigating factor albeit with some caveats (see below). However, cookies was the only practical attack scenario found with the tested versions of Safari. It’s possible that this could lead to compromise of other resources apart from cookies. Technically, the attacker can spoof the document.domain property. The number of affected devices may be of the order of 1 billion.

Cookies can also contain other sensitive information.Īll tested Safari versions on iOS, OS X, and Windows were vulnerable. Access to these cookies would allow hijacking authenticated sessions. Most websites which allow user logins store their authentication information (usually session keys) in cookies. An attacker could create web content which, when viewed by a target user, bypasses some of the normal cross-domain restrictions to access or modify HTTP cookies belonging to any website.
