Unrestricted File Upload in WordPress Simple File List Plugin

CVE-2025-34085

What is CVE-2025-34085?

CVE-2025-34085 is a security vulnerability identified in the Simple File List plugin for WordPress, specifically affecting versions prior to 4.2.3. This plugin is designed to facilitate file management within WordPress sites, enabling users to upload and organize files easily. However, the vulnerability allows unauthorized remote attackers to execute arbitrary code on the server by exploiting the plugin’s upload feature. Specifically, the issue arises from inadequate validation of file uploads after renaming, which permits an attacker to upload a malicious PHP file disguised as a different file type, such as a .png. Once uploaded, the attacker can change the file extension to .php, allowing it to be executed, thereby compromising the server and potentially leading to serious security breaches.

Potential impact of CVE-2025-34085

1. Remote Code Execution: The primary risk associated with this vulnerability is the ability for an attacker to execute arbitrary code on the server. This can allow the attacker to gain full control over the system, leading to unauthorized access to sensitive data, manipulation of site content, or further deployment of malware.

2. Compromise of User Data: Given that many WordPress installations handle sensitive information, exploitation of this vulnerability could result in the theft or exposure of critical user data, including personal information and credentials, leading to potential identity theft and privacy violations.

3. Increased Attack Surface for Subsequent Attacks: Successfully exploiting this vulnerability can provide a foothold for attackers, enabling them to deploy additional malicious tools or ransomware. Once embedded in the system, attackers can leverage this access to pivot to other connected systems or applications, significantly broadening their attack potential and increasing the overall risk to the organization.
