The vulnerability CVE-2017-7215 represents a cross site scripting flaw affecting the MISP (Malware Information Sharing Platform) security tool version 2.4.68 and earlier. This vulnerability exists in two distinct locations within the application's codebase, specifically in the index filter tool's javascript file misp2.4.68.js and the organization landing page template file landingpage.ctp. The flaw allows remote attackers to inject malicious web scripts or HTML content into the application's user interface, potentially compromising the security of users interacting with the platform.
The technical nature of this vulnerability stems from insufficient input validation and output encoding within the affected view elements. When users navigate to pages containing the vulnerable javascript functionality or organization landing page templates, the application fails to properly sanitize user-supplied data before rendering it in the browser context. This creates an environment where malicious actors can craft specially formatted input that gets executed as client-side code when other users view the affected pages. The vulnerability specifically impacts the index filter tool functionality and organization landing page rendering, both of which are core components of MISP's user interface design.
The operational impact of this vulnerability is significant for organizations relying on MISP for threat intelligence sharing and incident response activities. Attackers exploiting this XSS vulnerability could potentially steal session cookies, redirect users to malicious websites, deface the MISP interface, or execute arbitrary commands on behalf of authenticated users. Given that MISP is widely used by security professionals, government agencies, and organizations for sharing cyber threat intelligence, the compromise of a single instance could have cascading effects across multiple security teams. The vulnerability particularly affects users who have administrative privileges or access to sensitive threat data, as successful exploitation could lead to unauthorized access to critical security information and system resources.
This vulnerability maps to CWE-79 - Cross-site Scripting and aligns with ATT&CK technique T1059.007 - Command and Scripting Interpreter: JavaScript, highlighting the exploitation of client-side scripting vulnerabilities. Organizations should immediately upgrade to MISP version 2.4.69 or later to remediate this vulnerability, as the patch addresses the insufficient input validation in both the javascript filter tool and organization landing page components. Additional mitigations include implementing proper content security policies, enabling web application firewalls, and conducting regular security assessments of MISP installations to identify similar vulnerabilities in custom modifications or third-party integrations that may exist within the platform's ecosystem.
