Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in admin/themes/default/pages/manage_users.twig in the Users Management feature in the admin component in Chyrp before 2.5.1 allow remote authenticated users to inject arbitrary web script or HTML via the (1) user.email or (2) user.website field in a user registration.

The CVE-2014-7264 vulnerability represents a critical cross-site scripting flaw discovered in the Chyrp content management system prior to version 2.5.1. This vulnerability specifically targets the admin component's Users Management feature, which is a core administrative function responsible for handling user accounts and their associated metadata. The vulnerability exists within the template file admin/themes/default/pages/manage_users.twig, which serves as the user interface for managing registered users within the administrative dashboard. The flaw affects authenticated users who possess administrative privileges, making it particularly dangerous as it can be exploited by compromised or malicious administrators.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding within the user management interface. Attackers can exploit this weakness by injecting malicious scripts into the user.email or user.website fields during user registration processes. When the system displays these fields in the administrative user management interface, the malicious content is executed in the context of other administrators' browsers who view the affected pages. This occurs because the application fails to properly sanitize or escape user-provided data before rendering it in the web interface, creating an environment where arbitrary JavaScript code can be executed.
The operational impact of CVE-2014-7264 extends beyond simple data theft or defacement. As a persistent XSS vulnerability, it can be used to establish long-term access to administrative interfaces, potentially leading to complete system compromise. An attacker with administrative privileges can use this vulnerability to steal session cookies, modify user permissions, access sensitive data, or even inject backdoors into the system. The vulnerability affects the integrity of the entire user management system and can be leveraged to escalate privileges or conduct further attacks against the underlying infrastructure. This type of vulnerability is particularly concerning in web applications where administrative interfaces are accessible to multiple users, as it can be exploited to gain unauthorized access to critical system functions.
This vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and demonstrates the importance of implementing proper input validation and output encoding practices. From an ATT&CK framework perspective, this vulnerability maps to T1059.007 for script execution and T1566 for credential access, as it enables attackers to execute malicious code and potentially compromise administrative credentials. The vulnerability also reflects common security misconfigurations in web applications that fail to properly sanitize user input before displaying it in web interfaces. Organizations should implement comprehensive security measures including regular security assessments, input validation frameworks, and proper output encoding to prevent such vulnerabilities from being exploited in production environments. The fix for this vulnerability required proper sanitization of user input fields within the template rendering system to prevent malicious scripts from being executed when displaying user information in the administrative interface.
