| 제목 | moxi159753 mogu_blog_v2 <=v5.2 Server-Side Request Forgery (SSRF) |
|---|
| 설명 | mogu_blog_v2, a microservice-based blog system, contains an unauthenticated Server-Side Request Forgery (SSRF) and arbitrary file read vulnerability in the /file/uploadPicsByUrl endpoint. The Spring Security configuration allows public access to /file/** endpoints, and the uploadPictureByUrl method accepts arbitrary userUid/adminUid values without database validation. Attackers can inject systemConfig parameters and supply malicious URLs (including file:// URIs) in the urlList parameter. The application fetches the content via URLConnection.getInputStream() without protocol or host restrictions, saves it to a publicly accessible directory, and returns the URL in the response. This allows unauthenticated attackers to read arbitrary local files (e.g., /etc/passwd, configuration files, private keys), access internal network services, and retrieve cloud provider metadata, leading to complete system compromise. |
