CVE-2007-2376 in Dojo Toolkit
Summary
by MITRE
The Dojo framework exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page that retrieves the data through a URL in the SRC attribute of a SCRIPT element and captures the data using other JavaScript code, aka "JavaScript Hijacking."

The vulnerability described in CVE-2007-2376 represents a critical security flaw in the Dojo framework's data handling mechanisms that exposes sensitive information through improper JSON data transmission practices. This issue arises from the framework's failure to implement adequate protection measures when exchanging data using JavaScript Object Notation, creating an avenue for remote attackers to exploit the system's data retrieval processes. The vulnerability specifically manifests when the framework processes data through JavaScript code that retrieves information via URL parameters embedded in SCRIPT element SRC attributes, allowing malicious actors to intercept and capture sensitive data through carefully crafted web pages.
The technical implementation of this vulnerability stems from the framework's reliance on JSON data exchange without proper security controls or validation mechanisms. When the Dojo framework processes requests, it generates JSON responses that are intended for specific client-side consumption but lack sufficient protection against unauthorized access. Attackers can exploit this weakness by creating malicious web pages that embed SCRIPT elements with SRC attributes pointing to vulnerable Dojo endpoints. The JavaScript code running on these pages can then capture the JSON data being transmitted through these script elements, effectively bypassing traditional security controls that would normally prevent such data leakage.
This vulnerability directly impacts the confidentiality and integrity of data transmitted through the Dojo framework, as it allows attackers to perform what is commonly referred to as JavaScript hijacking attacks. The operational impact extends beyond simple data theft, as the compromised information could include user credentials, session tokens, personal data, or other sensitive business information that the framework is designed to protect. The attack vector specifically leverages the trust relationship between web browsers and script execution, where legitimate script tags are used to retrieve data, but the data is then captured by malicious JavaScript code that executes in the same context. This attack pattern aligns with common exploitation techniques documented in the attack mitigation framework and represents a classic example of insecure data handling practices that violate fundamental security principles.
The security implications of this vulnerability are significant as it undermines the trust model that web applications rely upon for secure data transmission. Organizations using the Dojo framework were particularly vulnerable to data exfiltration attacks that could occur without any authentication or authorization checks, making this a particularly dangerous flaw in applications that handle sensitive information. The vulnerability demonstrates the importance of implementing proper data validation and protection mechanisms, especially when dealing with JSON data exchanges that are inherently vulnerable to interception and manipulation. According to established security standards, this issue would be classified under CWE-200, which deals with information exposure, and represents a clear violation of the principle of least privilege in data handling practices. The attack method used in this vulnerability aligns with techniques documented in the MITRE ATT&CK framework under the data extraction and credential access categories, highlighting the need for comprehensive security measures that protect data both in transit and at rest. Organizations should implement proper CORS policies, JSONP validation, and data sanitization measures to prevent such vulnerabilities from being exploited in production environments.
