Overview
In this report, we are focusing on the CVE-2025-48523 vulnerability, a logic error in the onCreate function of SelectAccountActivity.java. This vulnerability allows unauthorized users to add contacts without necessary permissions, potentially leading to a local escalation of privilege. This can potentially compromise the system or leak data. The issue is especially alarming as it does not require user interaction for exploitation, making it a serious threat for any entity using the affected products.

How the Exploit Works
This exploit takes advantage of a logic error in the onCreate method of SelectAccountActivity.java. A malicious actor can manipulate the process to add contacts without the necessary permissions. This could allow them to escalate privileges locally, leading to potential system compromise or data leakage. And all of this can be done without the need for any user interaction.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This could be a sample Java code snippet, demonstrating how an attacker could manipulate the process to add contacts:
// Create a new account
Account newAccount = new Account("malicious_account", "com.example");
// Pass the new account to SelectAccountActivity
Intent intent = new Intent(context, SelectAccountActivity.class);
intent.putExtra("account", newAccount);
// Start the activity
context.startActivity(intent);Mitigation Guidance
To mitigate this vulnerability, users are strongly advised to apply the vendor patch as soon as it is available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure to monitor for and block potential exploit attempts.
