| タイトル | jeecgboot JeecgBoot <= v3.9.1 SSRF |
|---|
| 説明 | A direct Server-Side Request Forgery (SSRF) vulnerability exists in the /sys/common/uploadImgByHttp endpoint of jeecgboot_JeecgBoot. The application extracts a user-controlled fileUrl from the JSON request body and immediately performs an outbound HTTP request using HttpURLConnection without prior validation. Because file type filtering (SsrfFileTypeFilter.checkUploadFileType) is executed only after the external resource has been fully downloaded, an authenticated attacker can force the server to fetch arbitrary external or internal resources. This flaw can be exploited for internal network scanning, local service enumeration, or theft of sensitive cloud metadata credentials. |
