Description<\/h3>\n
\n # **CVE-2025-3914 – Arbitrary File Upload in Aeropage Sync for Airtable (WordPress)**<\/p>\n

## **Description**
\nThe **Aeropage Sync for Airtable** WordPress plugin (\u2264 v3.2.0) is vulnerable to **authenticated arbitrary file uploads** due to insufficient file type validation in the `aeropage_media_downloader` function. <\/p>\n

– **Attack Vector**: Authenticated (Subscriber+ privileges)
\n– **Impact**: Remote Code Execution (RCE) via malicious file upload
\n– **CVSS Score**: **8.8 (High)**
\n– **CVE ID**: **CVE-2025-3914** <\/p>\n

## **Vulnerable Code**
\nThe plugin fails to properly validate:
\n1. **File extensions**
\n2. **MIME types** (`$mediaObject[‘type’]` only checks superficial headers)
\n3. **File content** (no magic byte verification) <\/p>\n

### **Key Vulnerable Functions**
\n“`php
\n\/\/ Insufficient MIME check (bypassable)
\nif(aeropageValidateMediaType($mediaObject[‘type’], $mimeTypes) == false){…}<\/p>\n

\/\/ Direct file write (no sanitization)
\n$fp = fopen($uploadPathWithAttachmentID, ‘w’);
\nfwrite($fp, $downloadedfile);
\n“`<\/p>\n

## **Proof of Concept (PoC)**
\n### **Requirements**
\n– Python 3.x + `requests`
\n– Valid **Subscriber-level** WordPress credentials <\/p>\n

### **Exploit Steps**
\n1. **Authenticate** as a low-privilege user (Subscriber)
\n2. **Upload** a malicious `.php` file disguised as an image
\n3. **Execute** arbitrary code via the uploaded file <\/p>\n

“`bash
\npython3 CVE-2025-3914-PoC.py -u http:\/\/vulnerable-site.com -l subscriber -p password123
\n“`<\/p>\n

## **Mitigation**
\n1. **Update** to plugin version **> 3.2.0** (if available)
\n2. **Implement**:
\n – File **signature validation** (`finfo_file()`)
\n – **Randomized filenames**
\n – **.htaccess** restrictions in upload directories <\/p>\n

## **References**
\n– [CVE-2025-3914](https:\/\/nvd.nist.gov\/vuln\/detail\/CVE-2025-3914)
\n– [OWASP Unrestricted File Upload](https:\/\/owasp.org\/www-community\/vulnerabilities\/Unrestricted_File_Upload) <\/p>\n

—<\/p>\n

### **Key Improvements Over Generic PoC**
\n1. **WordPress-specific authentication** (handles cookies\/nonces)
\n2. **Fake JPEG header** + PHP payload (bypasses superficial checks)
\n3. **Automatic URL extraction** from response (if possible)
\n4. **Subscriber-level focus** (matches CVE details) <\/p>\n

### **Usage**
\n“`bash
\npython3 CVE-2025-3914-PoC.py -u http:\/\/wp-site.com -l subscriber -p password123
\n“`<\/p>\n

This provides a **realistic, weaponized exploit** for testing (use **only** on authorized systems!). Let me know if you’d like additional refinements. \ud83d\udd25<\/p><\/div>\n<\/p><\/div>\n
