With that you can add an auto forward rule to the victim’s Mail application.” “In my example case I wrote new Mail rules for the Mail application.
This will provide arbitrary file write permission to Library/Mail,” the researcher explained. ZIP includes the changes that you want to do to $HOME/Library/Mail. This left-behind symlink anchors the second stage of the attack. However, cleanup is not done right way and the symlink is left in place.” Based on the filename=1.txt.zip header, 1.txt gets copied to the mail director and everything works as expected. ZIP includes a symlink named Mail which points to victims’ $HOME/Library/Mail and file 1.txt,” said Kenttälä.
Mail will then automatically unpack those files. When a user receives the email, the Mail app will parse it to find any attachments with x-mac-auto-archive=yes header in place. ZIP files as attachments to the victim, according to the analysis. To exploit the bug, a cyberattacker could email two. “ is not unique in context of Mail, this can be leveraged to get unauthorized write access to ~/Library/Mail and to $TMPDIR using symlinks inside of those zipped files,” Kenttälä explained. However, the researcher discovered that parts of the uncompressed data are not removed from the temporary directory – and that the directory serves multiple functions, allowing attackers to pivot within the environment. When another Mail user receives this email, compressed attachment data is automatically uncompressed.” “In the valid use case, if the user creates email and adds the folder as an attachment it will be automatically compressed with ZIP and x-mac-auto-archive=yes is added to the MIME headers. He found that “mail has a feature which enables it to automatically uncompress attachments which have been automatically compressed by another Mail user,” he explained. Kenttälä said he discovered the bug ( CVE-2020-9922) by sending test messages and following Mail process syscalls.

Security experts have said average iPhone, iPad and Mac users do not need to worry, as these attacks are limited to specific targets, but the discovery still alarmed security professionals.A zero-click security vulnerability in Apple’s macOS Mail would allow a cyberattacker to add or modify any arbitrary file inside Mail’s sandbox environment, leading to a range of attack types.Īccording to Mikko Kenttälä, founder and CEO of SensorFu, exploitation of the bug could lead to unauthorized disclosure of sensitive information to a third party the ability to modify a victim’s Mail configuration, including mail redirects which enables takeover of victim’s other accounts via password resets and the ability to change the victim’s configuration so that the attack can propagate to correspondents in a worm-like fashion. "While that means they are not a threat to the overwhelming majority of our users, we continue to work tirelessly to defend all our customers, and we are constantly adding new protections for their devices and data." "Attacks like the ones described are highly sophisticated, cost millions of dollars to develop, often have a short shelf life, and are used to target specific individuals. "After identifying the vulnerability used by this exploit for iMessage, Apple rapidly developed and deployed a fix in iOS 14.8 to protect our users," said Ivan Krstić, head of Apple Security Engineering and Architecture, in a statement.
