The vulnerability CVE-2019-10254 represents a reflected cross-site scripting flaw discovered in the MISP (Malware Information Sharing Platform) software prior to version 2.4.105. This issue resides within the default layout template file app/View/Layouts/default.ctp, which serves as the foundational user interface component for the platform's web application. The vulnerability stems from insufficient input validation and output encoding mechanisms that fail to properly sanitize user-supplied data before rendering it within the web interface context. MISP is widely deployed by cybersecurity organizations for threat intelligence sharing and incident response coordination, making this vulnerability particularly concerning from an operational security perspective.
The technical implementation of this reflected XSS vulnerability occurs when user input parameters are directly incorporated into the HTML output without appropriate sanitization or encoding measures. Attackers can craft malicious URLs containing crafted script payloads that, when executed by unsuspecting users, can steal session cookies, perform unauthorized actions on behalf of victims, or redirect them to malicious sites. The vulnerability affects the default layout template which is fundamental to how the application renders pages, meaning that any user interaction that passes data through the web interface could potentially trigger this exploit. This type of vulnerability typically falls under CWE-79 which specifically addresses Cross-Site Scripting flaws in software applications.
The operational impact of this vulnerability extends significantly within cybersecurity environments where MISP is deployed. An attacker who successfully exploits this reflected XSS could gain unauthorized access to sensitive threat intelligence data, manipulate user sessions, or establish persistent access points within the threat sharing ecosystem. Given that MISP platforms often contain highly sensitive information about malware, attack patterns, and security incidents, the potential for data compromise is substantial. The vulnerability affects all users of affected MISP versions regardless of their role or permissions level, as reflected XSS typically requires only the victim to click a malicious link rather than any special authentication requirements. This makes the attack vector particularly dangerous in collaborative security environments where multiple analysts and security professionals interact with shared threat intelligence platforms.
Mitigation strategies for CVE-2019-10254 should prioritize immediate deployment of MISP version 2.4.105 or later, which contains the necessary patches to address the reflected XSS vulnerability. Organizations should also implement additional defensive measures including web application firewalls that can detect and block malicious script payloads, regular security scanning of web applications, and comprehensive user education about the dangers of clicking untrusted links. Network segmentation and monitoring of web traffic can help detect exploitation attempts, while implementing proper content security policies can provide additional protection layers against XSS attacks. Security teams should also conduct regular vulnerability assessments of their MISP installations and maintain up-to-date threat intelligence feeds to identify potential exploitation attempts. The vulnerability aligns with ATT&CK technique T1566 which covers social engineering through spearphishing with malicious attachments or links, making it particularly relevant for organizations that rely on MISP for threat intelligence sharing and incident response coordination.
