It is worth remembering that older versions of MacOS are particularly common with businesses that rely on older software that’s not compatible with later versions of the OS. If you have any Macs running versions of MacOS before Catalina, then it would be worth updating or confirming a separate patch has been applied if you can't use a more modern version of MacOS. While you are very unlikely to be materially affected by this flaw now, it’s worth bearing it in mind when you interact with seemingly harmless files online. As you can see from the security update (opens in new tab) Apple published after the fact, it does indeed contain a reference to this vulnerability. (Just search the page for "Yibelo.") It was quietly patched by Apple with the release of macOS 10.15 Catalina and the concurrent security updates to 10.14 Mojave and 10.13 High Sierra.Īpple investigates any claims before releasing information on them or confirming them. ![]() You haven't heard of this bug before because Yibelo privately disclosed it to Apple in 2019. That Safari flaw was patched by Apple in early 2017, but similar exploits might still be possible. "And that's basically gameover I believe!" Yibelo told Vice Motherboard. Yibelo told Vice Motherboard (opens in new tab) that if he were to chain the TextEdit exploit with another exploit, the two exploits together might be able to do much more damage to a Mac's security.įor example, his flaw combined with CVE-2017-2361 (opens in new tab), a flaw in the way Safari opens local Help files (opens in new tab), would have permitted the text file to execute JavaScript and hence do anything it wanted. That in itself is harmless, but Yibelo said it would be possible to abuse the HTML format so that the text file could send those details to a remote server. Yibelo found that text files could be engineered to list the contents of directories on the user's Mac, including password directories. The user of the Mac would not see any indication on the open TextEdit window that anything was going on behind the scenes. ![]() However, from there Yibelo discovered that by calling a function named AutoFS, which sends a request to mount external drives, it was possible to send a drive-mounting request to a server on the internet.ĭoing that would then reveal your Mac's IP address to the owner of the domain called. And that in turn would give them a pretty good idea of your location. Lo and behold, opening the HTML-containing text file in TextEdit was sufficient to execute basic HTML and CSS features and call local resources, but not reach out to online services. So Yibelo wondered what would happen if he put HTML encoding in a text file and opened it with TextEdit. It can also open Rich Text Format files (TextEdit's preferred format), Word documents and HTML files (the basic building blocks of the web). However, TextEdit isn't just a text editor.
