CVE-2025-24245 is a critical security vulnerability identified in Apple macOS, specifically addressed in macOS Sequoia 15.4. The vulnerability arises from a flaw in the system's password management verification process, where a malicious application can bypass authorization checks to access a user's saved passwords. The root cause relates to improper authorization (CWE-862), allowing unauthorized access without requiring privileges or user interaction. The fix implemented involves adding a delay between verification code attempts, effectively mitigating rapid brute-force or repeated unauthorized access attempts. The CVSS v3.1 base score of 9.8 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, no privileges required, and no user interaction needed. Although no active exploits have been reported, the vulnerability poses a significant risk due to the sensitive nature of saved passwords and the potential for credential theft leading to broader system compromise. The vulnerability affects all versions of macOS prior to Sequoia 15.4, making it critical for all macOS users to apply the update promptly. This vulnerability highlights the importance of robust authorization mechanisms in password management systems to prevent unauthorized access by malicious applications.

The exploitation of CVE-2025-24245 can have severe consequences for organizations and individual users worldwide. Unauthorized access to saved passwords can lead to credential theft, enabling attackers to impersonate users, access sensitive systems, and escalate privileges within networks. This can result in data breaches, unauthorized financial transactions, intellectual property theft, and disruption of business operations. The compromise of password integrity and availability further exacerbates the risk, potentially locking users out of their accounts or corrupting stored credentials. Given that the vulnerability requires no privileges or user interaction, it significantly lowers the barrier for attackers, increasing the likelihood of widespread exploitation once active exploits emerge. Organizations relying on macOS devices for critical operations, especially those in finance, healthcare, government, and technology sectors, face heightened risk. The vulnerability also undermines user trust in macOS security, potentially impacting Apple's reputation and user adoption.

To mitigate CVE-2025-24245, organizations and users should immediately update all macOS devices to version Sequoia 15.4 or later, where the vulnerability is patched. Beyond patching, organizations should implement strict application control policies to prevent installation of untrusted or malicious apps, leveraging macOS's built-in Gatekeeper and notarization features. Employ endpoint detection and response (EDR) solutions to monitor for suspicious app behavior indicative of unauthorized password access attempts. Regularly audit saved passwords and encourage users to use password managers with multi-factor authentication (MFA) support to reduce reliance on system-stored passwords. Network segmentation and least privilege principles should be enforced to limit lateral movement if credentials are compromised. Additionally, educating users about the risks of installing unverified applications and maintaining up-to-date backups can help reduce impact in case of exploitation. Finally, organizations should monitor threat intelligence feeds for any emerging exploits targeting this vulnerability to respond promptly.
