CVE-2007-2382 in Moo.fx
Summary
by MITRE
The Moo.fx 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-2007-2382 represents a critical security flaw in the Moo.fx JavaScript framework that exposes sensitive data through improper JSON handling. This issue occurs when the framework transmits data using JSON format without implementing any form of data protection or authentication mechanisms, creating an avenue for malicious actors to intercept and retrieve confidential information. The vulnerability specifically affects web applications that utilize Moo.fx for data exchange, making it particularly dangerous in environments where sensitive data flows through JavaScript-based communication channels.
The technical flaw manifests when JavaScript code retrieves data through a SCRIPT element with a SRC attribute pointing to a URL that returns JSON-formatted data. This approach fundamentally violates secure data transmission principles as it exposes the data stream directly to any JavaScript code that can access the page. The vulnerability stems from the framework's failure to implement proper content security measures, allowing attackers to craft malicious web pages that can capture and exfiltrate the JSON data being transmitted. This represents a classic case of inadequate data protection where the framework does not employ any form of encryption, authentication, or access control mechanisms to safeguard the transmitted information.
The operational impact of this vulnerability is significant as it enables remote attackers to perform data hijacking attacks without requiring any special privileges or complex exploitation techniques. Attackers can simply create a malicious web page that loads the vulnerable Moo.fx script and then use additional JavaScript code to capture the JSON data that flows through the framework. This type of attack falls under the broader category of cross-site scripting and data interception attacks, where the vulnerability allows for unauthorized data access and potential information disclosure. The attack vector is particularly insidious because it leverages the legitimate functionality of the JavaScript framework to execute unauthorized data retrieval operations.
From a cybersecurity perspective, this vulnerability aligns with CWE-312 (Cleartext Storage of Sensitive Information) and CWE-200 (Information Exposure) classifications, as it exposes sensitive data in an unencrypted format through JavaScript communication channels. The attack pattern corresponds to techniques described in the MITRE ATT&CK framework under T1566 (Phishing) and T1071.004 (Application Layer Protocol: DNS) where attackers can manipulate web content to capture data streams. Organizations using affected versions of the Moo.fx framework face potential data breaches, information disclosure, and unauthorized access to sensitive user information that could include personal data, session tokens, or other confidential information transmitted through the vulnerable JavaScript interface.
The recommended mitigations for this vulnerability include implementing proper data protection mechanisms such as JSONP with proper validation, utilizing secure communication protocols like HTTPS for all data transmission, and implementing authentication and authorization checks before data is returned. Developers should avoid using the vulnerable framework patterns and instead implement secure data handling practices including data encryption, proper access controls, and content security policies. Additionally, organizations should conduct regular security assessments to identify and remediate similar vulnerabilities in their JavaScript frameworks and ensure that all data transmission occurs through secure channels with appropriate protection mechanisms in place. The vulnerability underscores the critical importance of implementing proper security controls in client-side JavaScript applications where data handling and transmission occur in potentially untrusted environments.
