Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 3.3.0 版本之前的 DataGerry 中存在一个服务端模板注入漏洞。拥有 权限的已认证攻击者，可通过向 发起 POST 请求，将任意 Jinja2 负载存入 字段。随后，当用户调用 接口时，该负载将在非沙箱化的 Jinja2 环境中被渲染。攻击者可利用标准的 组件链（gadget chain），以 DataGerry Web 进程用户身份执行任意操作系统命令；在默认的 Docker 部署中，该进程确认为 root 用户，从而可实现远程代码执行（RCE）。

Vulnerability Title
DataGerry < 3.3.0 SSTI via DocAPI Template Rendering
Source: CVE Program / CVE List V5
Vulnerability Description
DataGerry before 3.3.0 contains a server-side template injection vulnerability that allows authenticated attackers with base.docapi.template.add permission to store arbitrary Jinja2 payloads in the template_data field via POST /rest/docapi/template, which is later rendered in a non-sandboxed Jinja2 environment when a user calls GET /rest/docapi/template/<id>/render/<object_id>. Attackers can exploit the standard cycler.__init__.__globals__.os gadget chain to execute arbitrary operating system commands as the DataGerry web process user, confirmed as root in default Docker deployments, achieving remote code execution.
