Discussion
Apple Mac OS X Safari Dashboard Widget Download Validation Bypass Vulnerability
Apple Mac OS X is susceptible to a Safari download validation bypass vulnerability when downloading Dashboard widgets. This issue is due to Safari improperly considering Dashboard widgets to be "safe" content.
It is demonstrated that an attacker can cause Safari to automatically download, and then install widgets into the users '~/Library/Widgets' directory. This happens without user intervention or notification.
Reportedly, once widgets have been automatically installed via Safari, the normal validation required for widgets to gain access to system resources is skipped, allowing complete system access to the malicious widgets, however, this has not been confirmed by Symantec.
This issue allows remote attackers to install malicious code into the dashboard without user intervention or knowledge. This will likely result in malicious script, or machine code being executed in the context of the targeted user.
Mac OS X version 10.4 is vulnerable to this issue.
