CVE-2014-10006 in Uploader
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in Maian Uploader 4.0 allow remote attackers to hijack the authentication of unspecified users for requests that conduct cross-site scripting (XSS) attacks via the width parameter to (1) uploader/admin/js/load_flv.js.php or (2) uploader/js/load_flv.js.php.

The CVE-2014-10006 vulnerability represents a critical cross-site request forgery vulnerability affecting Maian Uploader version 4.0, specifically targeting the application's handling of the width parameter within two distinct JavaScript files. This flaw operates as a sophisticated attack vector that leverages the fundamental weakness of CSRF mechanisms in web applications, where an attacker can manipulate user sessions to execute unauthorized actions. The vulnerability is particularly concerning because it combines CSRF exploitation with XSS capabilities, creating a multi-layered attack scenario that can potentially escalate to full system compromise. The affected files load_flv.js.php in both the admin and main uploader directories demonstrate a consistent code pattern that fails to validate or sanitize the width parameter, leaving the application exposed to malicious input manipulation.
The technical implementation of this vulnerability stems from the absence of proper CSRF token validation within the targeted JavaScript endpoints. When the width parameter is manipulated in requests to either uploader/admin/js/load_flv.js.php or uploader/js/load_flv.js.php, the application processes this input without adequate verification mechanisms. This parameter passing mechanism creates an exploitable path where an attacker can inject malicious JavaScript code through crafted requests that appear to originate from legitimate authenticated sessions. The vulnerability is classified under CWE-352, which specifically addresses Cross-Site Request Forgery issues, and operates in alignment with ATT&CK technique T1566.001 for initial access through spearphishing attachments, where the malicious JavaScript payload could be delivered through compromised user sessions. The flaw exploits the trust relationship between the web application and its users, allowing attackers to hijack active sessions and execute arbitrary code within the victim's browser context.
The operational impact of this vulnerability extends beyond simple session hijacking, as the combination of CSRF and XSS creates a dangerous attack surface that can lead to persistent malicious code execution. An attacker who successfully exploits this vulnerability can manipulate the width parameter to inject malicious scripts that will execute in the context of authenticated users, potentially leading to data theft, account takeover, or further exploitation of the web application. The attack requires minimal privileges and can be executed remotely, making it particularly dangerous in environments where users have administrative privileges or access to sensitive data. The vulnerability's persistence is enhanced by the fact that the malicious code execution occurs within the legitimate application context, making detection more difficult for security monitoring systems. This type of vulnerability can also serve as a stepping stone for more advanced attacks, potentially enabling privilege escalation or lateral movement within the compromised network.
Mitigation strategies for CVE-2014-10006 should focus on implementing robust CSRF protection mechanisms throughout the application's JavaScript components. The most effective approach involves implementing anti-CSRF tokens that are validated on each request, particularly for endpoints that process user-supplied parameters like the width parameter in question. Additionally, proper input validation and sanitization should be enforced at the application level to prevent malicious payloads from being processed. The implementation of Content Security Policy headers can provide additional protection against XSS execution, while regular security audits and code reviews should be conducted to identify similar vulnerabilities in other application components. Organizations should also consider implementing web application firewalls to detect and block suspicious parameter manipulation attempts. The vulnerability highlights the importance of maintaining up-to-date security practices and demonstrates how seemingly simple parameter handling can create significant security risks when proper validation mechanisms are absent, emphasizing the need for comprehensive security testing and adherence to secure coding practices as outlined in OWASP Top 10 and NIST cybersecurity guidelines.
