CVE-2024-27799

Vulnerability

Overview CVE-2024-27799 is a privacy vulnerability in Apple operating systems where an unprivileged application may be able to log keystrokes in other apps, including those using secure input mode [1]. The issue stems from insufficient entitlement checks, allowing a malicious app to capture sensitive input data without proper authorization.

Exploitation

To exploit this vulnerability, an attacker would need to convince a user to install a malicious app on their device. No additional privileges are required beyond normal app execution. The attack can monitor keystrokes from any app, bypassing secure input mode protections that are meant to safeguard passwords and other confidential information.

Impact

Successful exploitation enables an attacker to capture all keystrokes entered in other applications, including passwords, credit card numbers, and personal messages. This poses a significant risk to user privacy and data confidentiality, as sensitive information can be exfiltrated without the user's knowledge.

Mitigation

Apple addressed the issue with additional entitlement checks in iOS 16.7.8 and iPadOS 16.7.8, macOS Monterey 12.7.5, macOS Sonoma 14.5, and macOS Ventura 13.6.7 [1][4]. Users are advised to update their devices to these versions to protect against potential exploitation.
