CVE-2023-4634 is a critical vulnerability affecting the Media Library Assistant plugin for WordPress, specifically in versions up to and including 3.09. This vulnerability allows for Local File Inclusion and Remote Code Execution due to insufficient controls on file paths supplied to the 'mla_stream_file' parameter from the ~/includes/mla-stream-image.php file. Attackers can exploit this vulnerability to execute arbitrary code by supplying files via FTP, leading to serious security breaches.
With a CVSS score of 9.8, this vulnerability is classified as critical. The potential impact on confidentiality, integrity, and availability is high, making this issue particularly concerning for organizations using the affected plugin. The exploitability score of 3.9 indicates that this vulnerability is easy to exploit, thus increasing the urgency for organizations to address it.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. As attackers may leverage this vulnerability to gain unauthorized access, the implications could be severe. It is critical to remain vigilant and ensure that all installations of the Media Library Assistant plugin are updated to the latest version to prevent exploitation.
The vulnerability was published on September 6, 2023, and has been marked as modified since then. The root cause lies in the inadequate validation of file paths, which can lead to unauthorized file access and execution of arbitrary code.
Given the critical nature of this vulnerability, organizations must be proactive in their security measures to safeguard their systems against potential attacks.
Vulnerability Details
