In this article, we will Delve into one of the worst security flaws in Drupal, known as Drupal Geddon. We will explore the details of the security advisory that was posted on October 15, 2014, and the high risk it posed to websites running Drupal 7.31. Furthermore, we will analyze the vulnerability that allowed SQL injection attacks to occur.

2. Security Flaw in Drupal

Drupal Geddon referred to the security flaw found in Drupal, a popular content management system (CMS). This flaw was considered one of the most severe vulnerabilities discovered in the platform's history. The flaw's severity prompted the release of a security advisory to Raise awareness among Drupal users and encourage immediate action to mitigate the risk.

3. Understanding the Security Advisory

The security advisory posted in October 2014 provided critical information about the nature and extent of the security risk. It rated the vulnerability as highly critical, the maximum severity rating on the Scale. This meant that immediate action was required to address the issue. The advisory specified that all sites running Drupal 7.31 were at risk, making it a widespread concern throughout the Drupal community.

4. The Vulnerability: SQL Injection

The vulnerability that led to the Drupal Geddon exploit was related to SQL injection. SQL injection is a Type of security vulnerability that allows an attacker to manipulate a web application's database by inserting malicious SQL code. In the case of Drupal Geddon, the flaw allowed an attacker to execute arbitrary SQL commands and gain unauthorized access to the site's database.

5. Exploring the Code

To understand how the dangerous vulnerability existed in Drupal's code, let's take a closer look at the user profile editing feature. Upon examining the code, we discover that the presence of Hidden inputs in the password and confirm password fields introduces the potential for exploitation. These fields contain values that are posted as multi-dimensional associative arrays.

6. Exploiting the Vulnerability

The path to exploiting the vulnerability begins with editing the HTML of the user profile page. By injecting SQL code into the key of the array, an attacker can manipulate the SQL query and execute unauthorized commands. This allows them to modify database entries and potentially compromise the entire Website.

7. The Consequences of Drupal Geddon

The implications of Drupal Geddon were significant. The vulnerability allowed attackers to gain unauthorized access to Drupal websites running version 7.31 or below. As a result, numerous backdoors were implemented, posing a grave threat to the security and integrity of affected sites. Even updating to Drupal 7.32 did not guarantee the removal of these backdoors.

8. Tools to Detect Hacked Sites

To identify if a Drupal site had fallen victim to the Drupal Geddon exploit, several tools were developed. One such tool was "Drupal Geddon," a module specifically designed for Drupal. Additionally, the "drush download site_audit" tool provided another means of detecting security vulnerabilities on Drupal websites. However, these tools had limitations, and caution was advised in evaluating their results due to the complexity of the exploit.

9. Easy Fix for Drupal 7.32 and Below

For Drupal websites running version 7.32 or below, there was a simple fix to prevent exploitation of the vulnerability. By modifying the code responsible for handling array values, the risk of SQL injection attacks could be mitigated. This fix involved using the "array_values" method to convert the associative array to a normal array, removing any potentially malicious SQL code injected into the keys.

10. Upgrading to Drupal 7.34 or Higher

While the easy fix was a viable option for websites on Drupal 7.32 or below, upgrading to the latest version of Drupal was the optimal approach for long-term security. Upgrading to Drupal 7.34 or higher ensured that the vulnerability was patched and eliminated the possibility of future exploitation.

11. Conclusion

Drupal Geddon served as a wake-up call for the Drupal community, emphasizing the importance of robust security measures and prompt updates. It highlighted the severity of SQL injection vulnerabilities and the potential consequences of neglecting security patches. By understanding the nature of the exploit, website administrators can take the necessary steps to safeguard their Drupal sites against such vulnerabilities and ensure the ongoing security of their platforms.
