How the Exploit Works

The vulnerability CVE-2025-43233 works by exploiting insufficient access restrictions on macOS’s handling of HTTPS proxies. It allows a malicious app to pose as a HTTPS proxy, thereby bypassing the system’s security mechanisms and gaining unauthorized access to sensitive user data.

Conceptual Example Code

This conceptual example demonstrates how a malicious app might exploit this vulnerability.

POST /proxy/setting HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "proxy_app": "malicious_app", "action": "act_as_HTTPS_proxy" }

In this hypothetical example, the malicious app ‘malicious_app’ sends an HTTP POST request to the proxy setting endpoint of the target system. It attempts to set itself as the HTTPS proxy, which, if successful, would allow it to gain unauthorized access to sensitive user data.

Mitigation

Apple has already addressed this issue with improved access restrictions in subsequent macOS updates. Users are urged to update their system to the latest version as soon as possible. For macOS Sequoia, update to version 15.6 or later. For macOS Sonoma, update to version 14.7.7 or later. And for macOS Ventura, update to version 13.7.7 or later.
For temporary mitigation, users can apply a Web Application Firewall (WAF) or Intrusion Detection System (IDS). However, this should only be seen as a temporary solution while preparing for the system update. Always ensure the latest patches and updates are installed to prevent this and other potential vulnerabilities.

Impact: Possible system compromise or data leakage

Affected Products

Product | Affected Versions

macOS Sequoia | Up to 15.5
macOS Ventura | Up to 13.7.6
macOS Sonoma | Up to 14.7.6

How the Exploit Works

The root of this vulnerability lies in a permissions issue within the macOS operating systems. An application, when engineered with malicious intent or compromised, could exploit this flaw to bypass certain Privacy settings that the user or system administrator has set. This bypass could potentially expose sensitive user data or even lead to a complete system compromise if paired with other vulnerabilities.

Conceptual Example Code

While the exact mechanics of the exploit depend on the specific application and the Privacy preferences it seeks to bypass, a conceptual example might look something like this:

// Swift-based pseudo code
let privacyPref = UserDefaults.standard.string(forKey: "PrivacyPreferences")
if privacyPref != nil {
// The app is exploiting the vulnerability to bypass privacy preferences
UserDefaults.standard.set("Allow Full Access", forKey: "PrivacyPreferences")
}

This pseudo code represents an oversimplified example of how an application might change the user’s Privacy Preferences to gain broader access than it should have.

<script>
var buffer = new ArrayBuffer(128);
var int8View = new Int8Array(buffer);
for (var i = 0; i < 128; i++) {
int8View[i] = i * 2; // Fill the buffer with data
}
int8View[200] = 0; // Out-of-bounds write
</script>

This code attempts to write to an index that is outside the valid range of the buffer, resulting in an out-of-bounds access. An attacker could potentially use this to corrupt memory and execute arbitrary code.

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.
