Vulnerability Title
Reflected Cross-Site Scripting in MISP Event Filtering via taggedAttributes and galaxyAttachedAttributes Parameters
Vulnerability Description
MISP contains a reflected Cross-Site Scripting (XSS) vulnerability in the event attribute filtering query builder. The taggedAttributes and galaxyAttachedAttributes URL parameters were inserted into the query-builder rules without HTML escaping before being serialized as JSON and embedded inside a <script> element.
Because JsonTool::encode() uses JSON_UNESCAPED_SLASHES, an attacker-controlled value containing a closing </script> sequence could terminate the surrounding script element and inject arbitrary HTML or JavaScript. For example, a specially crafted viewEventAttributes URL could contain malicious content in one of the affected filter parameters.
An attacker could exploit the vulnerability by convincing an authenticated MISP user to follow a crafted URL. Successful exploitation would execute attacker-controlled JavaScript in the security context of the MISP instance and with the privileges of the victim's authenticated browser session. This could allow access to information available to the victim, modification of data through authenticated requests, or other actions permitted by the victim's MISP permissions.
The vulnerability is addressed by applying HTML escaping with h() to both scalar and array values before they are inserted into the DOM.

Vulnerability Title
MISP 跨站脚本漏洞
Vulnerability Description
MISP是MISP组织开源的一套开源的软件解决方案。该产品用于收集、存储、分发、共享网络安全指标,并具有威胁网络安全事件分析和恶意软件分析等功能。 MISP 2.5.45及之前版本存在跨站脚本漏洞,该漏洞源于taggedAttributes和galaxyAttachedAttributes参数在插入查询构建器规则时未进行HTML转义,可能造成反射型跨站脚本攻击,导致在用户浏览器中执行任意JavaScript。
