Executive brief
jishenghua jshERP is an open-source Enterprise Resource Planning (ERP) system used by small and medium-sized businesses to manage inventory, finance, and sales. A security vulnerability allows an administrative user to force the server to make unauthorized web requests to internal or external systems. This could be used to probe private internal network services or access sensitive cloud metadata, potentially leading to further compromise of the corporate infrastructure.
Technical details
A stored Server-Side Request Forgery (SSRF) vulnerability exists in jshERP-boot up to version 3.6. The flaw is located in the `insertPlatformConfig` function within `PlatformConfigService.java`. An attacker with administrative privileges can submit a malicious URL via the `platformValue` parameter at the `/platformConfig/add` endpoint (specifically when `platformKey` is set to `weixinUrl`). This value is persisted in the database without validation. When the system later invokes WeChat-related functions like `getAccessToken`, it retrieves the stored URL and passes it to `HttpClient.httpGet()`. This allows an attacker to trigger arbitrary outbound GET requests to internal services or cloud metadata endpoints. As of the advisory date, no official patch has been released.
