| Title | o2oa <=10.0.1-ce ssrf |
|---|
| Description | O2OA 10.0.1-ce is affected by a Server-Side Request Forgery (SSRF) weakness in the general module. The endpoint `POST /x_general_assemble_control/jaxrs/excel/upload/with/url` accepts a JSON field `fileUrl`, from which the server issues an HTTP GET and reads the response, without any protocol/host/IP allow-list and without blocking private-network or cloud-metadata addresses.
Any logged-in user (a normal account is sufficient; Cipher/Manager accounts likewise) can use this endpoint to discover internal hosts and ports, read internal HTTP services, and reach cloud metadata endpoints (e.g. `x.x.x.x`), thereby using the server as an internal-network probe/read pivot with a confidentiality impact. |
