Following our discovery of the “Shrootless” vulnerability, Microsoft uncovered a new macOS vulnerability, “powerdir,” that could allow an attacker to bypass the operating system’s Transparency, Consent, and Control (TCC) technology, thereby gaining unauthorized access to a user’s protected data. We shared our findings with Apple through Coordinated Vulnerability Disclosure (CVD) via Microsoft Security Vulnerability Research (MSVR). Apple released a fix for this vulnerability, now identified as CVE-2021-30970, as part of security updates released on December 13, 2021. We encourage macOS users to apply these security updates as soon as possible.
