CVE-2014-9337 in Mikiurl Wordpress Eklentisi
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in the Mikiurl Wordpress Eklentisi plugin 2.0 and earlier for WordPress allow remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the (1) twitter_kullanici or (2) twitter_sifre parameter in a kaydet action in the mikiurl.php page to wp-admin/options-general.php.

The CVE-2014-9337 vulnerability represents a critical cross-site request forgery flaw within the Mikiurl WordPress plugin version 2.0 and earlier, demonstrating how insufficient input validation and authentication mechanisms can create severe security risks for WordPress installations. This vulnerability specifically affects the plugin's administrative interface where it fails to implement proper CSRF protection measures, allowing remote attackers to exploit the lack of validation to manipulate administrative actions.
The technical flaw manifests through the absence of anti-CSRF tokens in the plugin's configuration handling mechanism. When administrators access the wp-admin/options-general.php page to manage the Mikiurl plugin settings, the application does not validate that requests originate from legitimate administrative sessions. Attackers can craft malicious requests that target the twitter_kullanici and twitter_sifre parameters within the kaydet action of mikiurl.php, effectively bypassing the normal authentication flow that should protect administrative functions from unauthorized modification.
This vulnerability creates a dangerous operational impact by enabling attackers to hijack administrator sessions and execute malicious actions without requiring valid credentials. The exploitation process involves tricking administrators into visiting malicious websites or clicking on compromised links that automatically submit requests to the vulnerable plugin's configuration page. The attacker can modify Twitter username and password settings, potentially leading to unauthorized access to Twitter accounts, data exfiltration, or the installation of malicious code through the compromised plugin.
The vulnerability directly maps to CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications, and aligns with ATT&CK technique T1078.004 for Valid Accounts and T1566.001 for Phishing. The flaw demonstrates how poorly implemented authentication controls can enable attackers to perform privilege escalation and maintain persistent access to WordPress administrative interfaces. The XSS capability mentioned in the description indicates that this vulnerability could potentially be leveraged to create more sophisticated attacks that combine CSRF exploitation with script injection techniques.
Mitigation strategies for this vulnerability require immediate plugin updates to versions that implement proper CSRF protection mechanisms including anti-CSRF token validation, session management improvements, and input sanitization. WordPress administrators should also implement additional security measures such as role-based access controls, regular security audits, and monitoring for unauthorized configuration changes. The vulnerability underscores the importance of maintaining up-to-date plugins and implementing comprehensive security frameworks that include proper authentication validation and request integrity checks to prevent similar attacks in other WordPress components.
