How the Exploit Works

The vulnerability in question allows an attacker to inject malicious objects into the data stream, which are then deserialized by the ThemeMakers Visual Content Composer. Since the software does not adequately validate or sanitize the incoming data, the injected object is executed within the application’s context, potentially leading to a system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This includes a crafted HTTP request carrying a malicious payload:

POST /ThemeMakers/Composer/Endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_object": "...serialized malicious object..." }

In this example, the “malicious_object” is a serialized object crafted to exploit the software’s deserialization vulnerability. Upon deserialization, the malicious code within the object is executed, potentially leading to a system compromise or data leakage.

Mitigation

The recommended mitigation for this vulnerability is to apply the vendor-provided patch. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking attempts to exploit this vulnerability. However, these measures should only be seen as temporary, and applying the vendor patch should be prioritized to ensure long-term security.

Product | Affected Versions

Firefox | < 142 Firefox ESR | < 115.27, < 128.14, < 140.2 Thunderbird | < 142, < 128.14, < 140.2 How the Exploit Works

The vulnerability operates through memory corruption in the GMP process. An attacker can exploit this to disrupt normal processing and potentially gain access to secure information. While the GMP process is heavily sandboxed, it operates with slightly different privileges from the content process. This difference in privileges could allow the attacker to bypass certain security measures and gain unauthorized access to sensitive data.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited. In this case, the attacker crafts a malicious payload that triggers the memory corruption in the GMP process.

POST /vulnerable/GMP_process HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "corrupt_memory()" }

Mitigation Guidance

The primary mitigation strategy for this vulnerability is to apply the vendor patch as soon as possible. These patches have been released for all affected versions of Firefox and Thunderbird. If you cannot apply the patch immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These tools will monitor your network for signs of this exploit and can block malicious traffic before it reaches your system. However, these are not long-term solutions and the patch should be applied as soon as feasible.

Overview

The CVE-2025-48148 vulnerability represents a critical security flaw discovered in the StoreKeeper B.V. software for WooCommerce. This vulnerability, specifically an unrestricted file upload vulnerability, threatens the security and integrity of e-commerce sites powered by WooCommerce that use the StoreKeeper B.V. extension. This issue is of paramount importance due to the potential for system compromise or data leakage, which could lead to unauthorized access to sensitive information, disruption of service, and a potential loss of consumer trust.

Vulnerability Summary

CVE ID: CVE-2025-48148
Severity: Critical (CVSS: 10.0)
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

StoreKeeper B.V. for WooCommerce | All versions through 14.4.4

How the Exploit Works

The unrestricted file upload vulnerability allows an attacker to upload and execute arbitrary code on the server that hosts the WooCommerce application. This is achieved by manipulating the file upload functionality in the StoreKeeper B.V. extension to accept files with dangerous types. With this capability, an attacker could potentially upload a script that, once executed, provides them with unauthorized access to the system or leads to a data leak.

Conceptual Example Code

The vulnerability might be exploited using a simple HTTP request like the following:

POST /storekeeper/upload HTTP/1.1
Host: vulnerable-woocommerce-site.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.php"
Content-Type: application/x-php
<?php
system($_GET['cmd']);
?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In this example, a malicious PHP script is uploaded which, when accessed via a specific URL, can execute arbitrary system commands supplied via the ‘cmd’ URL parameter.

Mitigations

The recommended mitigation strategy for this vulnerability is to apply the vendor-provided patch. Until that can be accomplished, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation, blocking attempts to exploit the vulnerability.

Affected Products

Product | Affected Versions

Cicool Builder | 3.4.4

How the Exploit Works

This vulnerability is exploited by the attacker sending a specially crafted HTTP request to the /administrator/auth/reset_password endpoint. The endpoint does not properly validate the request, allowing an attacker to reset the administrator’s password. With the new password, the attacker gains full system access, which could lead to unauthorized actions such as system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This is a hypothetical HTTP request:

POST /administrator/auth/reset_password HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"admin_email": "admin@example.com",
"new_password": "newPassword123"
}

Note: This is a simplified example for illustrative purposes. In a real attack scenario, the request may require additional elements or use more sophisticated techniques to bypass security measures.

Mitigation Guidance

The most effective mitigation for this vulnerability is to apply the vendor patch as soon as it becomes available. If immediate patching is not feasible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems should be configured to monitor and block requests to the vulnerable endpoint.
Remember, while these mitigation steps can help reduce the risk, the only complete solution is to patch the vulnerable software. Regularly updating all software and maintaining a robust security infrastructure is key to protecting your system from such vulnerabilities.
