CVE-2025-48547 in Android
Summary
by MITRE • 09/04/2025
In multiple locations, there is a possible one-time permission bypass 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 needed for exploitation.

This vulnerability represents a critical logic error in permission handling mechanisms that affects multiple system components simultaneously. The flaw exists in the fundamental access control logic where a one-time permission bypass occurs, allowing unauthorized elevation of privileges without requiring additional execution privileges. The vulnerability's impact extends across multiple locations within the system architecture, indicating a systemic design flaw rather than an isolated incident. This type of vulnerability directly relates to CWE-284 which addresses improper access control and specifically targets the principle of least privilege enforcement. The requirement for user interaction suggests that exploitation requires some form of social engineering or legitimate user activity to trigger the bypass condition, making it potentially more difficult to detect but equally dangerous when successful.
The operational impact of this vulnerability is severe as it enables local escalation of privilege without additional execution privileges, meaning an attacker who already has limited user access could potentially gain administrative or root-level permissions. This creates a pathway for attackers to bypass security controls that should normally prevent unauthorized access to critical system functions. The fact that multiple locations are affected suggests that the vulnerability exists in core system components or shared libraries that are utilized across different parts of the application or operating system. This widespread impact increases the attack surface significantly and could potentially affect various system services, applications, or subsystems that rely on the flawed permission handling logic.
The technical implementation of this vulnerability likely involves a race condition or state management error where the system fails to properly validate permissions during specific execution paths. Attackers would need to perform a sequence of actions that trigger the logic error, potentially involving timed operations or specific user interactions that cause the system to bypass normal permission checks. The vulnerability's classification aligns with ATT&CK technique T1068 which covers local privilege escalation through system flaws and T1548 which addresses abuse of application permissions. Security controls that might be bypassed include user access controls, privilege separation mechanisms, and audit logging systems that should normally prevent unauthorized privilege elevation.
Mitigation strategies should focus on implementing proper input validation and state management to prevent the logic error from occurring. System administrators should apply security patches as soon as they become available, as this vulnerability appears to be a design flaw that requires code-level fixes rather than configuration changes. Additional protective measures include implementing robust privilege separation, monitoring for unusual privilege escalation attempts, and ensuring that user interactions are properly validated before any permission changes occur. Organizations should also review their access control policies and conduct thorough security assessments to identify other potential vulnerabilities in similar permission handling mechanisms. The remediation process should involve comprehensive code review of affected components and implementation of proper permission validation at all critical access points to prevent similar issues from occurring in other parts of the system architecture.
