Vulnerability Summary

CVE ID: CVE-2025-43199
Severity: Critical (CVSS: 9.8)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

macOS Sequoia | Prior to 15.6
macOS Sonoma | Prior to 14.7.7
macOS Ventura | Prior to 13.7.7

How the Exploit Works

The exploit operates by exploiting a flaw in the permissions setup of the affected macOS versions. A malicious application, once installed and run by the user, can leverage this flaw to escalate its privileges to root level. This would give the application full administrative control over the system, enabling it to execute arbitrary commands, modify system configurations, access or alter data, or even install additional malicious software.

Conceptual Example Code

The following pseudocode represents conceptually how this vulnerability might be exploited:

// Malicious app payload
if (checkOSversion() < fixedVersion) {
privilegeEscalationToRoot();
// Execute malicious activities with root privileges
executeMaliciousActivities();
}

In the above, `checkOSversion()` is a function that checks the version of the operating system. If it is less than the version in which the vulnerability is fixed, the malicious application proceeds to escalate its privileges to root level using the `privilegeEscalationToRoot()` function. Finally, it executes its malicious activities using the `executeMaliciousActivities()` function.
Please note that this is a conceptual representation only and does not represent a real-world exploit code.

Mitigation Guidance

To mitigate this vulnerability, users are advised to update their affected macOS versions to the latest patched versions. If immediate patching is not possible, temporary mitigation can be achieved by using Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) to monitor and block suspicious activities. However, this should only be considered as a temporary solution, and patching should be done as soon as feasible.

Overview

The vulnerability, CVE-2025-43198, is a critical issue that was identified in certain versions of macOS, namely Sequoia 15.6 and Sonoma 14.7.7. This vulnerability, which has a CVSS Severity score of 9.8, could potentially lead to a massive system compromise or data leak if exploited. It primarily affects macOS users who have not yet updated to the fixed versions, and it matters because it can allow an app to access sensitive user data that should be protected.

Attack Vector: Application
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

macOS Sequoia | 15.6
macOS Sonoma | 14.7.7

How the Exploit Works

The exploit works by manipulating a specific application to access the protected user data. Due to the vulnerability in the code, the application can bypass the security measures and gain access to the data. This can potentially lead to system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This is a hypothetical scenario involving a malicious application that uses the exploit:

func exploitVulnerability() {
let protectedData = ProtectedUserData()
if let data = protectedData.access() {
print("Accessed protected user data: \(data)")
} else {
print("Failed to access protected user data")
}
}
class ProtectedUserData {
func access() -> String? {
// The following code contains the vulnerability CVE-2025-43198
// which allows unauthorized access to protected user data
return "Protected user data"
}
}
let maliciousApp = MaliciousApp()
maliciousApp.exploitVulnerability()

In this example, the `exploitVulnerability` function in the `MaliciousApp` class is able to access protected user data through the vulnerability in the `ProtectedUserData` class.

How to Mitigate the Issue

The best way to mitigate the issue is to apply the vendor patch from Apple, which removes the vulnerable code. The issue is fixed in later versions of macOS Sequoia and macOS Sonoma. As a temporary mitigation, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used. These can monitor and block malicious activities, providing an additional layer of security while the patch is being applied.

Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

macOS Sequoia | 15.6
macOS Sonoma | 14.7.7

How the Exploit Works

The vulnerability arises from a configuration issue associated with the Account-driven User Enrollment process. Even with Lockdown Mode activated, a malicious actor may exploit this vulnerability to gain unauthorized access to the system, potentially leading to system compromise or data leakage. This can be achieved by exploiting network protocols to manipulate the Enrollment process, thereby bypassing the security measures put in place by Lockdown Mode.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request that sends a malicious payload to a vulnerable endpoint.

POST /enroll-user HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"user": "malicious_user",
"password": "malicious_password",
"enrollment_token": "malicious_token"
}

In the above example, the attacker attempts to enroll a malicious user by sending a crafted HTTP request to the enrollment endpoint. The use of a malicious enrollment token is meant to trick the system into granting unauthorized access.

Mitigation

Until macOS Sequoia 15.6 and macOS Sonoma 14.7.7 users can apply the vendor patch to address this vulnerability, users are advised to implement a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure to detect and block potential exploit attempts.

Vulnerability Summary

CVE ID: CVE-2025-43186
Severity: Critical, CVSS score: 9.8
Attack Vector: Local/Remote
Privileges Required: None
User Interaction: Required
Impact: Unexpected application termination, potential system compromise and data leakage

Affected Products

Product | Affected Versions

watchOS | 11.6
iOS | 18.6
iPadOS | 18.6
tvOS | 18.6
macOS Sequoia | 15.6
macOS Sonoma | 14.7.7
visionOS | 2.6
macOS Ventura | 13.7.7

How the Exploit Works

This vulnerability exploits the improper memory handling mechanism in the affected Apple Operating Systems. When a file is parsed by the system, it can lead to unexpected application termination. This application termination could be leveraged by an attacker to execute arbitrary code or cause a denial-of-service condition. In the worst-case scenario, the vulnerability could be exploited to compromise the system entirely and leak sensitive data.

Conceptual Example Code

The following is a hypothetical example of how this vulnerability might be exploited. This pseudocode is purely illustrative:

import malicious_module
def exploit(target_file):
crafted_file = malicious_module.create('exploit_data')
target_file.parse(crafted_file)
if target_file.is_terminated_unexpectedly():
malicious_module.execute_arbitrary_code()
malicious_module.leak_data()

In this example, an attacker uses a malicious module to create a crafted file that, when parsed by the target file, causes the application to terminate unexpectedly. This unexpected termination then allows the attacker to execute arbitrary code or leak data from the system. This conceptual example underlines why all affected users should apply the recommended patches or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation.

Overview

In this blog post, we are going to discuss a critical vulnerability, CVE-2025-43184, that affects multiple versions of macOS. This vulnerability can potentially allow malicious actors to bypass sensitive settings within the Shortcuts app, which could lead to a system compromise or data leakage if exploited successfully. This is a cause for concern as macOS is widely used in both professional and personal settings, and unauthorized access to sensitive data or system resources can have far-reaching implications.

How the Exploit Works

This exploit takes advantage of a flaw in the user consent mechanism of the Shortcuts app in macOS. A malicious actor can create a seemingly harmless shortcut that, when executed, can bypass sensitive settings within the Shortcuts app. This can lead to a situation where an attacker may gain unauthorized access to sensitive data or system resources.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. In this case, a malicious shortcut could be created that, when executed, bypasses the user consent mechanism and accesses sensitive data.

#!/bin/bash
# Malicious shortcut script
open /Applications/Shortcuts.app --args bypassConsent=true
echo "Accessing sensitive data..."
# Code to access sensitive data goes here

Please note that this is a simplified representation of the exploit and actual exploit code would be significantly more complex and obfuscated.
In conclusion, users of the affected versions of macOS are strongly advised to update their systems to the latest version immediately. If unable to do so, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation against potential exploits.

How the Exploit Works

The vulnerability lies in the permissions system of the affected operating systems. An application with no special privileges can leverage this vulnerability to fingerprint a user, leading to potential data leaks or system compromise. The attack requires user interaction, indicating that the exploit may involve tricking the user into performing certain actions or accepting certain permissions.

Conceptual Example Code

Below is a hypothetical example of how this vulnerability might be exploited. This is not a real exploit code but merely an illustrative example:

# This is a conceptual pseudo-code, not a working exploit
def exploit():
app_request_permission("Sensitive Permission")
if user_grants_permission():
fingerprint = gather_user_information()
send_data_to_attacker(fingerprint)

In this conceptual example, the malicious app requests a sensitive permission. If the user grants the permission, the app gathers user information to create a fingerprint and sends this data to the attacker. The actual exploit would be more complex and could involve the use of various techniques to deceive the user or hide the malicious activity.
