CVE-2008-1916 in Ubercart Module
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in the Ubercart 5.x before 5.x-1.0-rc1 module for Drupal allow remote attackers to inject arbitrary web script or HTML via text fields intended for the (1) address and (2) order information, which are later displayed on the order view page and unspecified other administrative pages, a different vulnerability than CVE-2008-1428.

The CVE-2008-1916 vulnerability represents a critical cross-site scripting flaw discovered in the Ubercart e-commerce module for Drupal versions 5.x prior to 5.x-1.0-rc1. This vulnerability specifically targets the module's handling of user input in text fields designated for address and order information, creating a persistent security risk that affects multiple administrative interfaces within the Drupal ecosystem. The flaw stems from inadequate input sanitization and output encoding mechanisms that fail to properly escape malicious content before rendering it on web pages, making it particularly dangerous for online commerce platforms where sensitive customer data is processed.
The technical implementation of this vulnerability occurs when attackers exploit the lack of proper validation and sanitization of text fields that are intended to collect address and order information from users. When this data is later displayed on order view pages and other administrative interfaces without proper HTML escaping or context-aware encoding, malicious scripts embedded within the text fields can be executed in the browsers of unsuspecting administrators or customers who view these pages. This creates a persistent XSS vector that can be leveraged to steal session cookies, perform unauthorized administrative actions, or redirect users to malicious sites. The vulnerability operates at the application layer and requires no special privileges to exploit, making it particularly dangerous for web applications handling sensitive commerce data.
The operational impact of CVE-2008-1916 extends beyond simple script execution, as it enables attackers to gain unauthorized access to administrative functions and compromise the integrity of customer data within the Drupal-based e-commerce system. Attackers can leverage this vulnerability to inject malicious code that persists across multiple user sessions and page views, potentially allowing them to modify order information, steal customer credentials, or manipulate the entire shopping cart functionality. The vulnerability's persistence across different administrative pages means that a single injection can compromise multiple areas of the system, making the attack surface significantly larger than typical XSS vulnerabilities. This aligns with CWE-79 which categorizes cross-site scripting flaws as weaknesses in input validation and output encoding, and follows ATT&CK techniques related to code injection and credential access through web application exploitation.
Organizations affected by this vulnerability should implement immediate mitigations including upgrading to the patched version 5.x-1.0-rc1 of the Ubercart module, implementing proper input validation and output encoding for all user-supplied data, and configuring web application firewalls to detect and block suspicious script injection patterns. Additionally, administrators should review and sanitize all existing order data that may have been compromised, implement proper content security policies to prevent script execution, and establish regular security auditing procedures to identify similar vulnerabilities in other modules. The remediation process should also include comprehensive staff training on secure coding practices and input validation techniques to prevent similar issues in custom-developed modules or future versions of the platform.
