There have been previous TCC exploits, including one that utilizes Apple’s built in Time Machine utility, that have since been patched as well. The company also took time to promote its own Defender for Endpoint enterprise security solution, which was able to prevent those exploits even before Apple patched them. Microsoft is urging macOS users to ensure that their version of MacOS Monterey is updated with the latest patch. This allowed Microsoft to silently change the home directory and execute the same kind of attack as the first exploit.įortunately, Microsoft again notified Apple of the vulnerability, and it was patched last month. This binary is responsible for making system level configuration changes, including access to the TCC database. This new exploit allows an attacker to use code injection to change binary called /usr/libexec/configd. The second proof of concept exploit came about because a change in MacOS Monterey’s dsimport tool broke the first exploit. Microsoft reported these initial findings to Apple in July 2021, though the exploit apparently still worked, despite Apple fixing a similar exploit demonstrated at Black Hat 2021. Microsoft was even cheekily able to give Teams mic and camera access. The first “proof of concept” exploit basically planted a fake TCC database file and changed the user’s home directory.īy doing this, Microsoft was able to change the settings on any application or enable access to the microphone or camera. Once the user responds, that request is stored in the database and future requests will follow the user’s previous input.Īccording to Microsoft, the “powerdir” vulnerability, also known as CVE-2021-30970, was actually exploited two times by their security researchers. ![]() Otherwise, a prompt is shown to the user to explicitly grant or deny access.
