How the Exploit Works

The vulnerability CVE-2025-48546 resides in the checkPermissions function of SafeActivityOptions.java. A logic error within the code allows an attacker to launch activities in the background. The attacker can exploit this vulnerability locally without needing additional execution privileges or user interaction, potentially leading to an escalation of privilege. A successful exploitation can compromise the system’s integrity or result in data leakage.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit the vulnerability:

public class ExploitCVE202548546 {
public static void main(String[] args) {
// Create an instance of SafeActivityOptions
SafeActivityOptions safeActivity = new SafeActivityOptions();
// Exploit the logic error in checkPermissions to launch a background activity
safeActivity.checkPermissions("malicious_background_activity");
}
}

This example illustrates the attacker invoking the checkPermissions method with a malicious background activity.

Remediation

To mitigate the risk posed by CVE-2025-48546, it is highly recommended to apply the vendor-provided patch. In the absence of an immediate patch, implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. However, these should not be considered long-term solutions as they may not fully prevent exploitation of the vulnerability.
