macOS vulnerability analysis and mitigation

CVE-2023-23498 is a logic issue in Apple's Mail application that affects iOS 15.7.3 and iPadOS 15.7.3, macOS Ventura 13.2, iOS 16.3 and iPadOS 16.3. The vulnerability was discovered by Jose Lizandro Luevano and disclosed on February 27, 2023. The issue affects the email forwarding functionality when using Exchange accounts (Apple Support, NVD).

The vulnerability stems from a logic issue in the Mail application's state management when handling email forwarding in Exchange accounts. When a user attempts to forward an email, the system may incorrectly select the quoted original message from the wrong email. The vulnerability has been assigned a CVSS v3.1 base score of 3.3 (Low) with a vector string of CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N, indicating local access is required and user interaction is necessary (NVD).

The vulnerability can result in incorrect email content being quoted when forwarding emails from Exchange accounts. This could potentially lead to sensitive information from the wrong email being included in forwarded messages, which might result in unintended information disclosure (Apple Support).

Apple has addressed this vulnerability by improving state management in the affected systems. The fix is available in iOS 15.7.3 and iPadOS 15.7.3, macOS Ventura 13.2, iOS 16.3 and iPadOS 16.3. Users are advised to update their devices to these versions or later to mitigate the vulnerability (Apple Support).
