Vulnerability Title
MISP remote code execution via arbitrary rdkafka configuration path
Source: CVE Program / CVE List V5
Vulnerability Description
MISP allowed an authenticated site administrator to set the Kafka_rdkafka_config setting to an arbitrary filesystem path. MISP subsequently parsed the referenced INI file and passed its options to rdkafka. A crafted attacker-controlled configuration file could use rdkafka options such as plugin.library.paths to load an external library, resulting in arbitrary code execution with the privileges of the MISP process. An attacker could leverage a MISP-writable location, such as an uploaded file or administrative image, to host the malicious configuration file. The issue is fixed by restricting the setting to absolute .ini files located only in approved configuration directories outside the webroot and MISP upload targets.

Vulnerability Title
MISP 软件供应链问题漏洞
Source: CNNVD (China National Vulnerability Database)
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 2.5.41及之前版本存在软件供应链问题漏洞，该漏洞源于允许通过身份验证的站点管理员将Kafka_rdkafka_config设置设置为任意文件系统路径，进而解析引用的INI文件并将选项传递给rdkafka，攻击者控制的配置文件可利用plugin.library.paths等选项加载外部库，从而导致以MISP进程权限执行任意代码。
