Overview

CVE-2024-49720 is a critical vulnerability that has been identified in multiple functions of Permissions.java. Due to a logic error in the code, this vulnerability allows potential attackers to override a user’s location permissions. The issue is significant as it can lead to local escalation of privilege without requiring any additional execution privileges. Furthermore, user interaction is not required for the vulnerability to be exploited, thereby increasing the risk of potential system compromise or data leakage.

Vulnerability Summary

How the Exploit Works

The exploit takes advantage of a logic error in the code of Permissions.java. This error allows the state of a user’s location permissions to be overridden. As a result, an attacker can achieve local escalation of privilege without needing additional execution privileges or user interaction. This can lead to potential system compromise or data leakage.

Conceptual Example Code

While a specific example is beyond the scope of this summary, a conceptual exploit might involve sending specific requests to the vulnerable system to manipulate the logic error. Here’s a high-level illustration of how such an attack might be structured:

Permissions userPermissions = getUserPermissions(userId);
userPermissions.setLocationPermission(false); // supposed to set location permission to false
// A logic error allows the following line to override the above setting
boolean result = userPermissions.checkLocationPermission();
if (result) {
// Exploit: The system allows actions that should require location permission
performActionThatRequiresLocationPermission();
}

In this conceptual example, even though the location permission is set to false, the logic error allows the permission check to return true, thereby allowing the attacker to perform actions that should require location permission.
