How the Exploit Works

The vulnerability works by exploiting a use-after-free condition in multiple locations of the affected products. This condition arises when a piece of memory is freed and then used again, leading to potential corruption of the memory. An attacker can exploit this vulnerability to elevate their privileges on the system, gaining unauthorized access to sensitive information or even taking control of the system.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This is a simplified representation and real-world exploitation might require a more complex approach.

#include <stdlib.h>
int main() {
char *buffer = malloc(100);  // Allocating memory
free(buffer);                // Freeing the memory
buffer[50] = 'A';            // Use after free
}

In this pseudo-code, a buffer is allocated and then freed, but it’s used again after being freed. This results in memory corruption which could be exploited to escalate privileges and compromise the system.

Mitigation

It’s recommended to apply the vendor-supplied patches as soon as possible to mitigate this vulnerability. If patches are not yet available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These solutions can help detect and block attempts to exploit this vulnerability until a more permanent solution can be implemented.

How the Exploit Works

The vulnerability arises from a confused deputy problem in multiple functions of AppRestrictionsFragment.java. A confused deputy is a computer program that is innocently fooled by some other party into misusing its authority. In this case, a malicious actor could manipulate the software into bypassing the intent security check, thereby escalating their privileges on the system.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This pseudocode demonstrates how a malicious actor might trick the software into bypassing the intent security check.

Intent maliciousIntent = new Intent();
maliciousIntent.setComponent(new ComponentName("com.example.vulnerableapp", "com.example.vulnerableapp.VulnerableActivity"));
// Bypass security check
AppRestrictionsFragment.confuseDeputy(maliciousIntent);
startActivity(maliciousIntent);

Note:
The above code is a simplified representation and may not work exactly as shown. It is intended to illustrate the nature of the vulnerability.

Recommended Mitigation

The primary recommended mitigation for CVE-2025-32326 is to apply the vendor-provided patch. If this is not immediately feasible, temporary mitigation can be achieved by implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor, identify, and block malicious activity. However, this should be considered a stopgap measure until the patch can be applied, as it may not fully protect against all potential exploits.

Affected Products

Product | Affected Versions

Java | All versions prior to patch

How the Exploit Works

The vulnerability resides in the onCommand function of ActivityManagerShellCommand.java. An attacker with local access could exploit this issue by confusing the deputy function, causing it to launch activities arbitrary, potentially leading to a local escalation of privilege. This could result in unauthorized information disclosure, modification, or disruption of service, all without requiring additional execution privileges or user interaction.

Conceptual Example Code

Below is a conceptual example of how an attacker might exploit this vulnerability:

ActivityManagerShellCommand am = new ActivityManagerShellCommand();
am.onCommand("malicious_activity");

In the example above, the `onCommand` method is invoked with a malicious activity. Since the deputy function is confused and no additional execution privileges are needed, this could lead to an arbitrary activity launch.

Mitigation Recommendations

The primary mitigation strategy for this vulnerability is to apply the vendor patch. If this is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. However, these measures only serve to mitigate the risk and do not fully address the underlying vulnerability. As such, they should only be considered as a stopgap solution until the vendor patch can be applied.

Overview

This report focuses on the CVE-2025-32323 vulnerability found in the getCallingAppName function of Shared.java. This vulnerability allows malicious actors to deceive users into granting file access by manipulating the text in a permission popup. This could lead to local escalation of privilege, potentially compromising the system and leading to data leakage.

Vulnerability Summary

CVE ID: CVE-2025-32323
Severity: High (7.8)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Shared.java | All versions prior to patch update

How the Exploit Works

The exploit works by manipulating the text presented in a permission popup. The vulnerability stems from improper input validation in the getCallingAppName function of Shared.java. An attacker can craft deceptive text that can trick a user into granting file access, thus leading to a local privilege escalation. This escalation can potentially compromise the system and leak sensitive data.

Conceptual Example Code

A conceptual exploit might involve injecting malicious code into the permission popup. However, actual exploit code cannot be provided to prevent misuse. Here is a simplified example of a deceptive text payload:

String maliciousPayload = "Your system requires an update. Grant access to proceed";
PopupWindow popup = new PopupWindow();
popup.setTitle("System Update Required");
popup.setMessage(maliciousPayload);
popup.show();

In this example, the malicious payload is a deceptive message that tricks the user into believing that a system update is required and prompts them to grant file access.

Mitigation Guidance

To mitigate this vulnerability, users should apply the vendor-provided patch as soon as it becomes available. In the meantime, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These solutions can help detect and prevent attempted exploits of this vulnerability.

Affected Products

Product | Affected Versions

[Product A] | [All Versions < 1.0] [Product B] | [All Versions < 2.3] How the Exploit Works

The vulnerability resides within the `isSafeIntent` function of the AccountTypePreferenceLoader.java file. A confused deputy issue in this function can potentially allow an attacker to bypass an intent type check, which is integral for determining the type of action to be taken by the system. Bypassing this check enables an attacker to escalate their privileges within the system without any additional execution privileges or user interaction, which can lead to unauthorized access, system compromise, or data leakage.

Conceptual Example Code

This could be a conceptual example of how the vulnerability might be exploited:

// Create an intent with a malicious type
Intent maliciousIntent = new Intent();
maliciousIntent.setType("malicious/type");
// Bypasses the isSafeIntent check due to the confused deputy issue
boolean result = isSafeIntent(maliciousIntent);
// If the check is bypassed, the malicious intent is executed, leading to privilege escalation
if (result) {
startActivity(maliciousIntent);
}

The above example is purely conceptual and simplified for illustrative purposes. Real-world exploitation might involve more complex steps or interactions.

Mitigation

To mitigate the risk posed by this vulnerability, it is advised to apply patches provided by the vendor as soon as possible. In the absence of a patch or while waiting for a patch to be released, utilizing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary protection. Further, regular auditing of system logs and monitoring for any suspicious activities can also assist in early detection and prevention of potential exploits.
