CVE-2025-32322 in Android
Summary
by MITRE • 09/04/2025
In onCreate of MediaProjectionPermissionActivity.java , there is a possible way to grant a malicious app a token enabling unauthorized screen recording capabilities due to improper input validation. 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-2025-32322 resides within the MediaProjectionPermissionActivity.java component of an Android system, specifically in the onCreate method where improper input validation creates a security flaw that allows malicious applications to obtain screen recording tokens. This represents a critical weakness in the Android permission system that directly impacts the integrity of the device's security model and could enable unauthorized access to sensitive user data through screen capture capabilities.
The technical flaw manifests through inadequate validation of input parameters during the creation of media projection permissions, allowing an attacker to manipulate the permission flow and obtain tokens that grant screen recording capabilities without proper authorization. This vulnerability operates at the system level where the Android framework should enforce strict validation of permission requests, but instead fails to properly verify the legitimacy of the requesting application or the parameters associated with the screen recording request. The flaw aligns with CWE-20, which addresses improper input validation, and specifically relates to the improper handling of permission requests in Android's security framework.
The operational impact of this vulnerability extends beyond simple unauthorized screen recording capabilities to potentially enable full local privilege escalation without requiring any additional execution privileges or user interaction. An attacker could leverage this flaw to gain elevated system privileges and access sensitive information that would normally be protected by the Android permission model. The vulnerability's exploitation does not require user interaction, making it particularly dangerous as it can be triggered automatically when the affected application is installed or when system processes attempt to handle media projection requests. This characteristic places the vulnerability in the ATT&CK matrix under privilege escalation techniques where adversaries can leverage system-level weaknesses to gain elevated access.
The security implications of this vulnerability are severe as it directly undermines the fundamental security principle of least privilege that Android implements to protect user data. Once an attacker obtains the screen recording token through this vulnerability, they could capture sensitive information displayed on the screen including passwords, private messages, banking information, and other confidential data. The vulnerability's ability to enable local privilege escalation means that an attacker could potentially access system-level resources and data that should remain protected from unauthorized access, creating a significant risk for both individual users and enterprise environments where sensitive data is processed and stored.
Mitigation strategies should focus on implementing proper input validation and parameter checking within the MediaProjectionPermissionActivity.java component, ensuring that all permission requests are properly authenticated and validated before any screen recording tokens are granted. System updates should enforce stricter validation of permission requests and implement additional checks to verify the legitimacy of applications requesting screen recording capabilities. Organizations should also consider implementing application whitelisting policies and monitoring for unusual permission requests that could indicate exploitation attempts. The fix should address the root cause by ensuring that the onCreate method properly validates all input parameters and implements proper access controls that prevent unauthorized applications from obtaining screen recording tokens, thereby maintaining the integrity of Android's permission model and protecting user data from unauthorized access.
