CVE-2024-44147 is a vulnerability identified in Apple’s iOS and iPadOS platforms that allows an application to gain unauthorized access to the local network. The root cause is improper state management within the operating system’s network access controls, which fails to adequately restrict app permissions regarding local network interactions. This flaw enables malicious or compromised applications to bypass intended security boundaries and communicate with devices on the same local network without explicit user consent or privileges. The vulnerability affects all versions prior to iOS 18 and iPadOS 18, where Apple has implemented fixes to improve state management and enforce stricter network access controls. The vulnerability is classified under CWE-269 (Improper Privilege Management), indicating that the system grants more privileges than intended. The CVSS v3.1 base score is 7.7, with vector AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, indicating that the attack requires local access (the app must be installed on the device), has low attack complexity, requires no privileges or user interaction, and impacts confidentiality and integrity significantly but not availability. No known exploits have been reported in the wild yet, but the potential for abuse is high given the sensitive nature of local network access. This vulnerability could be exploited to perform network reconnaissance, intercept or manipulate local network traffic, or pivot attacks to other devices on the network. The fix is included in iOS 18 and iPadOS 18, which improves state management to prevent unauthorized local network access by apps.

The impact of CVE-2024-44147 is significant for organizations and individuals relying on Apple mobile devices. Unauthorized local network access can lead to exposure of sensitive internal network resources, enabling attackers to perform reconnaissance, intercept communications, or launch further attacks against other devices on the network. This compromises confidentiality and integrity of data within the local network environment. Since the vulnerability requires no user interaction or privileges, malicious apps could silently exploit this flaw once installed, increasing the risk of stealthy attacks. Enterprises with BYOD policies or those deploying iOS/iPadOS devices in sensitive environments face elevated risks of data leakage and lateral movement within their networks. Although availability is not directly impacted, the breach of confidentiality and integrity can have cascading effects on organizational security posture, compliance, and trust. The absence of known exploits in the wild suggests limited immediate threat but does not diminish the urgency for remediation given the ease of exploitation and high impact.

To mitigate CVE-2024-44147, organizations and users should promptly update all affected Apple devices to iOS 18 or iPadOS 18, where the vulnerability has been addressed through improved state management. Beyond patching, organizations should enforce strict app vetting policies, limiting installation to trusted sources such as the official Apple App Store and employing Mobile Device Management (MDM) solutions to control app permissions and network access. Network segmentation can reduce the impact by isolating critical systems from general user devices. Monitoring network traffic for unusual local network communications from mobile devices can help detect exploitation attempts. Additionally, educating users about the risks of installing untrusted apps and regularly reviewing app permissions related to local network access will further reduce exposure. For high-security environments, consider disabling local network access permissions for apps unless explicitly required. Finally, maintain an inventory of devices and OS versions to ensure timely updates and compliance with security policies.
