CVE-2014-4309 in Openfiler
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Openfiler 2.99 allow remote attackers to inject arbitrary web script or HTML via the (1) TinkerAjax parameter to uptime.html, or remote authenticated users to inject arbitrary web script or HTML via the (2) MaxInstances, (3) PassivePorts, (4) Port, (5) ServerName, (6) TimeoutLogin, (7) TimeoutNoTransfer, or (8) TimeoutStalled parameter to admin/services_ftp.html; the (9) dns1 or (10) dns2 parameter to admin/system.html; the (11) newTgtName parameter to admin/volumes_iscsi_targets.html; the User-Agent HTTP header to (12) language.html, (13) login.html, or (14) password.html in account/; or the User-Agent HTTP header to (15) account_groups.html, (16) account_users.html, (17) services.html, (18) services_ftp.html, (19) services_iscsi_target.html, (20) services_rsync.html, (21) system_clock.html, (22) system_info.html, (23) system_ups.html, (24) volumes_editpartitions.html, or (25) volumes_iscsi_targets.html in admin/.

The CVE-2014-4309 vulnerability represents a significant cross-site scripting flaw in Openfiler 2.99 that exposes multiple attack vectors allowing remote code execution through malicious web script injection. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically targeting input validation and output encoding mechanisms within the web interface of the storage management platform. The affected application processes user-supplied data without adequate sanitization, creating persistent XSS opportunities across various administrative endpoints.
The technical exploitation of this vulnerability occurs through multiple parameter injection points within the web application's administrative interface. Attackers can manipulate the TinkerAjax parameter in uptime.html to inject malicious scripts, while authenticated users can exploit parameters such as MaxInstances, PassivePorts, Port, ServerName, TimeoutLogin, TimeoutNoTransfer, and TimeoutStalled in admin/services_ftp.html to execute arbitrary code. Additionally, the dns1 and dns2 parameters in admin/system.html provide further injection points, along with the newTgtName parameter in admin/volumes_iscsi_targets.html. The most concerning aspect involves the User-Agent HTTP header manipulation across multiple pages including language.html, login.html, password.html, account_groups.html, account_users.html, services.html, services_ftp.html, services_iscsi_target.html, services_rsync.html, system_clock.html, system_info.html, system_ups.html, volumes_editpartitions.html, and volumes_iscsi_targets.html in the admin directory.
The operational impact of this vulnerability extends beyond simple script injection, as it allows attackers to potentially escalate privileges and gain unauthorized access to the storage management system. Remote attackers can leverage these XSS flaws to steal session cookies, redirect users to malicious sites, or inject malicious content that could compromise the entire storage infrastructure. The vulnerability affects both unauthenticated and authenticated attack scenarios, making it particularly dangerous as it can be exploited by anyone with network access to the Openfiler interface. According to ATT&CK framework, this vulnerability maps to T1566 (Phishing) and T1059 (Command and Scripting Interpreter) techniques, as attackers can use the XSS payloads to establish persistent access or execute malicious commands through the compromised web interface.
Mitigation strategies for CVE-2014-4309 require comprehensive input validation and output encoding across all user-supplied parameters within the Openfiler administration interface. Organizations should implement strict sanitization of all HTTP headers, particularly the User-Agent field, and ensure proper HTML escaping for all dynamic content generation. The recommended approach involves applying the latest security patches from Openfiler, implementing Content Security Policy headers to restrict script execution, and conducting thorough input validation at multiple layers including the application firewall and web server configuration. Additionally, network segmentation and access control measures should be enforced to limit exposure of the administrative interface to trusted networks only. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other web applications within the storage infrastructure environment.
