CVE-2010-0370 in Nodeblock
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in the Node Blocks module 5.x-1.1 and earlier, and 6.x-1.3 and earlier, a module for Drupal, allows remote authenticated users, with permissions to create or edit content and administer blocks, to inject arbitrary web script or HTML via the edit-title parameter (aka block title).

The vulnerability described in CVE-2010-0370 represents a critical cross-site scripting flaw within the Node Blocks module for Drupal content management systems. This vulnerability affects versions 5.x-1.1 and earlier, as well as 6.x-1.3 and earlier, making it a significant concern for Drupal installations that rely on this module for block management functionality. The flaw specifically resides in how the system processes the edit-title parameter when users create or edit content and administer blocks, creating an avenue for malicious script injection.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding within the Node Blocks module's handling of block titles. When authenticated users with appropriate permissions submit block titles through the edit interface, the system fails to properly sanitize or escape the input data before rendering it in the web page context. This allows attackers to inject malicious JavaScript code or HTML content directly into the block title field, which then executes in the browsers of other users who view the affected pages.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to perform various malicious activities including session hijacking, credential theft, and redirection to malicious websites. Since the vulnerability requires only authenticated users with content creation or block administration permissions, it can be exploited by insiders or compromised accounts with relatively low privileges. The attacker's ability to inject arbitrary web scripts means they can potentially steal cookies, redirect users to phishing sites, or even execute more sophisticated attacks through the compromised user sessions.
This vulnerability maps directly to CWE-79, which describes Cross-Site Scripting flaws in web applications, and aligns with several ATT&CK techniques including T1566 for credential access through phishing and T1059 for command and scripting interpreter usage. The attack surface is particularly concerning because it leverages legitimate administrative functionality, making the malicious behavior harder to detect through normal security monitoring. Organizations using Drupal with the Node Blocks module should immediately implement mitigations including input validation, output encoding, and privilege restrictions to prevent exploitation. The recommended solution involves upgrading to patched versions of the Node Blocks module, implementing proper input sanitization, and establishing strict access controls for content creation and block management functions. Additionally, security teams should conduct comprehensive vulnerability assessments to identify any other modules that may exhibit similar input handling issues.
