Summary
by MITRE
Cross-site scripting (XSS) vulnerability in the Camtasia Relay module 6.x-2.x before 6.x-3.2 and 7.x-2.x before 7.x-1.3 for Drupal allows remote authenticated users with the "view meta information" permission to inject arbitrary web script or HTML via unspecified vectors related to the meta access tab.

The CVE-2015-5487 vulnerability represents a critical cross-site scripting flaw within the Camtasia Relay module for Drupal platforms, affecting versions 6.x-2.x prior to 6.x-3.2 and 7.x-2.x prior to 7.x-1.3. This vulnerability specifically targets authenticated users who possess the "view meta information" permission, creating a significant security risk within Drupal-based content management systems that utilize this module for media content management and delivery. The flaw exists in the meta access tab functionality, which serves as a critical interface for managing and viewing metadata associated with media content within the platform.
The technical nature of this vulnerability stems from insufficient input validation and output encoding within the Camtasia Relay module's implementation. When authenticated users access the meta access tab and interact with certain metadata fields, the application fails to properly sanitize user-supplied input before rendering it in web pages. This allows malicious actors to inject arbitrary HTML code or JavaScript payloads that execute in the context of other users' browsers. The vulnerability operates as a reflected XSS attack vector, where malicious scripts are executed when legitimate users view the affected metadata content. According to CWE classification, this represents a CWE-79: Cross-site Scripting vulnerability, specifically manifesting as a reflected XSS flaw that occurs when user-provided data is directly included in web responses without proper sanitization.
The operational impact of this vulnerability extends beyond simple script injection, potentially enabling attackers to perform session hijacking, deface websites, steal sensitive information, or redirect users to malicious sites. Since the vulnerability requires only the "view meta information" permission, it can be exploited by users who have relatively low privileges within the system, making it particularly dangerous for organizations that grant broad access to their Drupal platforms. The attack vector operates through the meta access tab functionality, which is commonly used by content managers and administrators to review media metadata, creating a high-impact scenario where legitimate users inadvertently execute malicious code. This vulnerability directly aligns with ATT&CK technique T1059.001 for Command and Scripting Interpreter, specifically JavaScript execution within web browsers, and T1531 for Account Access Removal, as it can lead to unauthorized access through session manipulation.
Organizations affected by this vulnerability should immediately implement the patch releases available for both Drupal 6 and 7 versions of the Camtasia Relay module, specifically upgrading to version 6.x-3.2 or 7.x-1.3 respectively. Additionally, administrators should consider implementing web application firewalls to monitor and filter suspicious input patterns, while conducting thorough security reviews of all user permissions to minimize the attack surface. Regular security assessments should include verification of module integrity and proper input validation across all Drupal installations. The vulnerability demonstrates the critical importance of proper sanitization of user inputs in web applications, particularly in content management systems where metadata handling is a common operational function. Security teams should also implement monitoring for suspicious activity patterns related to the meta access tab functionality and establish incident response procedures for potential XSS exploitation attempts.
