CVE-2014-9146 in Fiyo
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Fiyo CMS 2.0.1.8 allow remote attackers to inject arbitrary web script or HTML via the (1) view, (2) id, (3) page, or (4) app parameter to the default URI or the (5) act parameter to dapur/index.php.

The vulnerability identified as CVE-2014-9146 represents a critical cross-site scripting flaw affecting Fiyo CMS version 2.0.1.8, exposing the application to remote code execution through malicious web script injection. This vulnerability stems from inadequate input validation and sanitization mechanisms within the content management system's core processing logic. The flaw specifically manifests in five distinct parameter injection points including view, id, page, app parameters within the default URI structure and the act parameter within the dapur/index.php endpoint, creating multiple attack vectors for potential exploitation.
The technical implementation of this vulnerability aligns with CWE-79 which categorizes cross-site scripting as a code injection flaw where untrusted data is improperly integrated into web pages without adequate sanitization or encoding. The vulnerability operates by allowing attackers to inject malicious scripts through user-controllable parameters that are directly reflected in the application's response without proper validation. When legitimate users access pages containing these malicious inputs, their browsers execute the injected scripts within the context of the vulnerable application, potentially compromising user sessions and enabling further attack vectors.
From an operational impact perspective, this vulnerability presents significant risks to both administrators and end-users of the affected CMS platform. Attackers could leverage these XSS vulnerabilities to hijack user sessions, steal sensitive authentication tokens, redirect users to malicious domains, or even perform unauthorized actions within the CMS interface. The attack surface is particularly concerning given that the vulnerable parameters are commonly used in navigation and content management operations, meaning that exploitation could occur through routine user interactions with the application's interface. This vulnerability directly maps to several ATT&CK techniques including T1566 for initial access through malicious web content and T1059 for command and control through script execution.
The mitigation strategies for CVE-2014-9146 should prioritize immediate patching of the Fiyo CMS to a version that implements proper input validation and output encoding mechanisms. Organizations should implement comprehensive parameter validation at all entry points where user input is processed, ensuring that all parameters undergo strict sanitization before being incorporated into dynamic web content. Additionally, the implementation of Content Security Policy headers can provide an additional layer of protection against XSS attacks by restricting script execution within the application context. Regular security auditing of web applications should include thorough testing of parameter handling and input validation mechanisms to prevent similar vulnerabilities from emerging in the future. The vulnerability demonstrates the critical importance of input validation in web applications and serves as a reminder of the necessity for comprehensive security testing throughout the software development lifecycle.
