Title
Apache Unomi远程代码执行漏洞
Description
Apache Unomi是一个可用于多系统的java开源客户数据平台，用于管理用户配置文件和与该配置文件相关的数据，Unomi在2019年被宣布成为Apache的顶级项目。由于Apache Unomi是作为运行在Apache Karaf中的OSGi应用程序构建的，因此它具有极好的可扩展性和易用性。 Apache Unomi在1.5.2之前版本中存在远程代码执行漏洞。该平台具有内置的规则系统和用户细分的概念，当用户需要为配置文件下发数据时，可以使用OGNL或MVEL类的表达式语言未受限制的执行查询操作，从而导致了Unomi容易受到表达式注入攻击，攻击者可以利用该漏洞发送符合语法的恶意表达式使Unomi服务器执行任意代码和系统命令。
