CVE-2024-54560 is a logic-based security vulnerability affecting Apple’s iOS, iPadOS, macOS Sequoia, tvOS, and watchOS platforms. The root cause is inadequate enforcement of permission checks that allow a malicious application to modify other installed applications without possessing the required App Management permission. This bypass occurs due to a flaw in the operating system’s logic that governs app modification rights. The vulnerability was identified and fixed in the latest OS versions released by Apple, including iOS 18 and iPadOS 18. The CVSS 3.1 base score is 5.5, reflecting a medium severity level. The attack vector is local (AV:L), meaning the attacker must have local access to the device, and the attack complexity is low (AC:L), requiring no special conditions beyond user interaction (UI:R). No privileges are required (PR:N), and the scope remains unchanged (S:U). The impact is primarily on integrity (I:H), as the malicious app can alter other apps, potentially injecting malicious code or altering app behavior, but confidentiality and availability are not directly affected. No known exploits have been reported in the wild to date. This vulnerability is categorized under CWE-269 (Improper Privilege Management). The fix involves improved permission checks to prevent unauthorized app modifications. The vulnerability affects all versions prior to the patched releases, and organizations should apply updates promptly to mitigate risk.

The primary impact of CVE-2024-54560 is on the integrity of applications installed on Apple devices. A malicious app exploiting this vulnerability can alter other apps without proper authorization, potentially injecting malicious code, modifying app behavior, or bypassing security controls embedded within those apps. This can lead to unauthorized data manipulation, execution of malicious payloads under the guise of legitimate apps, and erosion of user trust in the platform’s security. Although confidentiality and availability are not directly impacted, the integrity compromise can facilitate further attacks such as data exfiltration or privilege escalation. For organizations, this vulnerability poses a risk to mobile device management, enterprise app security, and any security-sensitive workflows relying on app integrity. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk in environments where devices may be physically accessible or where social engineering can induce user interaction. The absence of known exploits in the wild reduces immediate risk but does not preclude future exploitation attempts. Failure to patch could expose organizations to targeted attacks, especially those with high-value data or critical infrastructure relying on Apple platforms.

1. Immediate deployment of Apple’s security updates: Upgrade all affected devices to iOS 18, iPadOS 18, macOS Sequoia 15, tvOS 18, and watchOS 11 or later versions where the vulnerability is fixed. 2. Enforce strict app installation policies: Use Mobile Device Management (MDM) solutions to restrict installation of apps from untrusted sources and enforce app integrity checks. 3. Educate users about social engineering risks: Since user interaction is required, training users to avoid installing untrusted apps or clicking suspicious links can reduce exploitation likelihood. 4. Monitor device behavior for anomalies: Implement endpoint detection and response (EDR) tools capable of detecting unusual app modification activities or unauthorized app behavior. 5. Limit physical access to devices: Enforce physical security controls to prevent unauthorized local access to devices, especially in high-risk environments. 6. Conduct regular security audits: Periodically review app permissions and installed software to detect unauthorized modifications. 7. Use app sandboxing and integrity verification features: Leverage Apple’s built-in security mechanisms to detect and prevent unauthorized app tampering. 8. Coordinate with Apple support for incident response: In case of suspected compromise, engage Apple’s security teams for guidance and forensic analysis.
