How the Exploit Works

The exploit takes advantage of a confused deputy problem in onCreate method of ChooserActivity.java. This security flaw allows an attacker to access and view images of other users in the local system without requiring any additional execution privileges or user interaction. The vulnerability is exploited locally and does not require any special permissions or user interaction, making it a high-risk vulnerability.

Conceptual Example Code

public class Exploit {
public static void main(String[] args) {
ChooserActivity chooserActivity = new ChooserActivity();
chooserActivity.onCreate(null);
UserImage[] allImages = chooserActivity.getAllUserImages();
for (UserImage image : allImages) {
System.out.println(image.getUri());
}
}
}

In this conceptual example, an attacker creates an instance of ChooserActivity and calls the onCreate method. Then, the attacker uses the getAllUserImages method to retrieve all user images and print their URIs.

Mitigation

To mitigate the risk presented by CVE-2025-22416, it is recommended to apply the vendor-provided patch. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Due to the severity of this vulnerability, immediate action should be taken to secure affected systems.
