Overview
The vulnerability, CVE-2025-48535, is a serious security flaw found in the AppRestrictionsFragment.java component. It can be exploited by manipulating a parcel mismatch which can result in a ‘launch anywhere’ vulnerability. This flaw affects all systems running applications with the vulnerable component. It is of significant concern due to its potential for a local escalation of privilege and the possibility of system compromise or data leakage.

How the Exploit Works
The exploit works by manipulating the deserialization process in the AppRestrictionsFragment.java component. By exploiting a parcel mismatch, an attacker can cause the system to erroneously launch activities anywhere. This could lead to local escalation of privilege, thereby allowing the attacker to gain unauthorized access to system resources or data.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This sample HTTP request sends a ‘malicious_payload’ which manipulates the parcel mismatch.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "parcel_mismatch": "exploit_code" }In this example, ‘exploit_code’ would be replaced with code specifically crafted to exploit the parcel mismatch vulnerability.
Mitigation
To mitigate this vulnerability, it is advised to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Regular monitoring and updating of systems is always a recommended practice to maintain a secure environment.
