CVE-2024-23710 in Android
Summary
by MITRE • 05/08/2024
In assertPackageWithSharedUserIdIsPrivileged of InstallPackageHelper.java, there is a possible execution of arbitrary app code as a privileged app due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability identified as CVE-2024-23710 resides within the Android operating system's package installation framework, specifically in the InstallPackageHelper.java file where the assertPackageWithSharedUserIdIsPrivileged method contains a critical logic flaw. This issue represents a significant security weakness that allows malicious applications to potentially execute arbitrary code with elevated privileges typically reserved for system-level components. The vulnerability stems from an improper validation mechanism that fails to correctly verify the privilege level of applications attempting to share user identifiers, creating a pathway for privilege escalation without requiring any user interaction or additional malicious payloads.
The technical flaw manifests as a logic error in the privilege validation process where the system incorrectly determines that an application with a shared user identifier should be granted privileged status when it should not meet the necessary criteria for such elevated permissions. This misclassification occurs during the package installation phase when the system evaluates whether an application can assume privileged capabilities based on its shared user identifier configuration. The vulnerability falls under CWE-284 which specifically addresses improper access control mechanisms, and more broadly aligns with ATT&CK technique T1068 which covers privilege escalation through local exploits. The flaw essentially creates a backdoor mechanism where unauthorized applications can bypass normal security boundaries and assume the privileges of legitimate system applications.
The operational impact of this vulnerability is severe as it enables local privilege escalation without any user interaction requirements, meaning that a malicious application could automatically exploit this weakness to gain elevated system privileges. This creates a dangerous scenario where an attacker could potentially install a malicious application that, upon execution, immediately escalates its privileges to gain full system control. The implications extend beyond simple code execution as the escalated privileges could allow for complete system compromise, data exfiltration, persistent backdoor installation, and modification of critical system components. The vulnerability affects the core Android package management system, making it a fundamental weakness that could be exploited across all affected Android versions.
Mitigation strategies for CVE-2024-23710 should focus on immediate patch deployment from device manufacturers and Google, as this represents a critical security flaw requiring urgent remediation. Organizations should implement comprehensive monitoring for unauthorized application installations and privilege escalation attempts, while also ensuring that all Android devices receive timely security updates. The fix should involve correcting the logic error in the assertPackageWithSharedUserIdIsPrivileged method to properly validate privilege levels and prevent unauthorized elevation of privileges. Additionally, system administrators should consider implementing application whitelisting policies and enhanced security monitoring to detect potential exploitation attempts. The vulnerability highlights the critical importance of proper access control validation in system-level components and underscores the need for rigorous security testing of core Android framework elements to prevent similar logic flaws from compromising system integrity and user security.
