Unpatched High-Severity Vulnerability Affects Apple macOS Computers

Cybersecurity researchers on Tuesday disclosed information of an unpatched vulnerability in macOS Finder that could be abused by remote adversaries to trick users into functioning arbitrary instructions on the machines.

“A vulnerability in macOS Finder allows documents whose extension is inetloc to execute arbitrary commands, these information can be embedded inside of e-mail which if the person clicks on them will execute the instructions embedded inside them without having offering a prompt or warning to the consumer,” SSD Protected Disclosure claimed in a write-up printed currently.

Park Minchan, an independent security researcher, has been credited with reporting the vulnerability which has an effect on macOS versions of Huge Sur and prior.


The weak spot arises thanks to the method macOS processes INETLOC data files — shortcuts to world wide web destinations this kind of as RSS feeds or Telnet connections that contains username and password for SSH — resulting in a situation that will allow commands embedded in these data files to be executed with out any warning.

“The situation right here INETLOC is referring to a ‘file://’ protocol which makes it possible for jogging locally (on the user’s personal computer) saved documents,” SSD stated. “If the INETLOC file is attached to an electronic mail, clicking on the attachment will trigger the vulnerability without having warning.”


Although newer variations of macOS have blocked the ‘file://’ prefix, applying ‘File://’ or ‘fIle://’ has been identified to circumvent the look at correctly. We have arrived at out to Apple, and we will update the tale if we hear back.
