Welcome to our detailed examination of CVE-2020-13671, a severe security vulnerability in the Drupal content management system (CMS). This article aims to provide an in-depth understanding of the issue, its impact on your systems, and how you can ensure your operations remain safe and secure through efficient patch management.
First, let's delve into what Drupal is and why it's a significant component in many web environments. Drupal is an open-source CMS used worldwide for building websites and applications. Its flexibility and robust feature set make it a preferred choice for many developers and corporations to manage their digital content. However, like all software, Drupal is susceptible to security vulnerabilities which can be exploited by malicious entities.
The specific vulnerability addressed here, CVE-2020-13671, has been classified with a HIGH severity with an impact score of 8.8, indicating its potential high risk to systems if left unpatched. It affects multiple versions of Drupal, specifically versions prior to Drupal Core 9.0.8, 8.9.9, 8.8.11, and 7.74.
The core of the problem lies in Drupal's handling of file uploads. The CMS fails to properly sanitize certain filenames on uploaded files, which can result in these files being misinterpreted as having an incorrect extension. Consequently, these files might be served with an inappropriate MIME type or, more alarmingly, executed as PHP code. This can occur particularly in certain hosting configurations that execute PHP code found within files having specific extensions.
This vulnerability is critical because it allows attackers to execute arbitrary code on the server, potentially taking over the server or spreading malware. For businesses and individuals using Drupal, this poses a significant security risk, potentially leading to data theft, website defacement, or worse.
To mitigate this risk, it is crucial for administrators and site owners to update their Drupal installations to the latest versions that have patched this vulnerability. Specifically, updates are available for Drupal versions 9.0.8, 8.9.9, 8.8.11, and 7.74, which resolve this issue.
Now, how can you as a Drupal user, ensure your site is safe? Here are a few steps:
