Overview
CVE-2025-32322 is a high-risk vulnerability that resides in MediaProjectionPermissionActivity.java. It potentially allows a malicious app to abuse a token granting process, thus enabling unauthorized screen recording. This vulnerability affects a wide range of systems and applications that use this module and poses a significant risk due to the potential for system compromise and data leakage.
Vulnerability Summary
CVE ID: CVE-2025-32322
Severity: High (7.8 CVSS)
Attack Vector: Application
Privileges Required: None
User Interaction: None
Impact: Unauthorized screen recording leading to potential system compromise or data leakage
Affected Products
Product | Affected Versions
Android OS | 9.0, 10.0, 11.0
How the Exploit Works
The vulnerability stems from improper input validation in the onCreate function of MediaProjectionPermissionActivity.java. This flaw allows a malicious app to bypass the permission mechanism and obtain a token enabling screen recording capabilities. This kind of privilege escalation can potentially allow an attacker to record sensitive activities on the screen, leading to data leakage or even a full system compromise.
Conceptual Example Code
While the exact exploitation method for this vulnerability is dependent on the specific application and environment, a conceptual example of exploiting this vulnerability might look like this:
public class MaliciousApp extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MediaProjectionManager manager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
Intent intent = new Intent(manager.ACTION_MEDIA_PROJECTION);
intent.putExtra("android.intent.extra.INTENT", getMaliciousIntent());
startActivityForResult(intent, REQ_CODE);
}
private Intent getMaliciousIntent() {
// Returns an intent with malicious data or actions
}
}Mitigation Guidance
To mitigate this vulnerability, it is recommended to apply the official vendor patch. If a patch is not available or cannot be applied immediately, use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary countermeasure. Regularly review your application and system logs for any suspicious activity.
