Summary
by MITRE
Cross-site request forgery (CSRF) vulnerability in the OSF module 7.x-3.x before 7.x-3.1 for Drupal, when the OSF Import module is enabled, allows remote attackers to hijack the authentication of administrators for requests that create new OSF datasets via unspecified vectors.

The CVE-2015-7233 vulnerability represents a critical cross-site request forgery flaw within the OSF module version 7.x-3.x of Drupal platforms prior to version 7.x-3.1. This vulnerability specifically affects systems where the OSF Import module is enabled, creating a significant security risk for organizations relying on Drupal-based content management systems. The flaw allows remote attackers to exploit administrative privileges through maliciously crafted requests that manipulate the authentication mechanisms of system administrators. The vulnerability's impact extends beyond simple data manipulation as it enables attackers to create new OSF datasets within the target system, potentially leading to unauthorized data creation and system compromise.
The technical implementation of this CSRF vulnerability stems from inadequate validation of request origins and lack of proper anti-CSRF token mechanisms within the OSF Import module's administrative interfaces. When administrators access the OSF dataset creation functionality, the module fails to properly verify that requests originate from legitimate administrative sessions. This weakness creates an exploitable condition where attackers can craft malicious web pages or email attachments that, when visited by authenticated administrators, automatically submit requests to create new datasets without the administrator's knowledge or consent. The vulnerability operates through unspecified vectors that likely involve manipulation of HTTP headers, form submissions, or AJAX requests that bypass standard authentication checks.
The operational impact of CVE-2015-7233 is substantial, particularly for organizations running Drupal systems with OSF Import functionality enabled. Attackers exploiting this vulnerability can gain unauthorized administrative access to create, modify, or delete OSF datasets, potentially leading to data corruption, information leakage, or complete system compromise. The attack requires minimal technical expertise and can be executed remotely, making it particularly dangerous for organizations with limited security monitoring capabilities. Successful exploitation could result in unauthorized data creation, modification of existing datasets, or potential privilege escalation within the Drupal environment, affecting the integrity and availability of the entire system.
Organizations should immediately upgrade to OSF module version 7.x-3.1 or later to remediate this vulnerability, as no effective workarounds exist for the underlying CSRF flaw. System administrators should conduct comprehensive security assessments of all Drupal installations with OSF Import modules enabled, ensuring proper patch management procedures are in place. The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in software applications, and corresponds to ATT&CK technique T1566.002 for the initial access phase of cyber operations. Security teams should implement additional monitoring for suspicious administrative activities and ensure that all web applications maintain proper CSRF protection mechanisms, including the implementation of anti-CSRF tokens and proper origin validation checks.
