DescriptionCVE.org

A security flaw has been discovered in JeecgBoot up to 3.9.1. This vulnerability affects the function CommonController.uploadImgByHttp/HttpFileToMultipartFileUtil.httpFileToMultipartFile/HttpFileToMultipartFileUtil.downloadImageData of the file CommonController.java of the component uploadImgByHttpEndpoint. Performing a manipulation results in server-side request forgery. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. Upgrading the affected component is recommended. The vendor confirmed the issue and will provide a fix in the upcoming release.

AnalysisAI

Server-side request forgery in JeecgBoot up to 3.9.1 allows authenticated remote attackers to manipulate the CommonController.uploadImgByHttp endpoint and trigger arbitrary HTTP requests from the server, with publicly available exploit code and vendor confirmation of the issue. The vulnerability affects the image upload functionality through HttpFileToMultipartFileUtil.httpFileToMultipartFile and downloadImageData methods, enabling attackers with valid credentials to abuse the application as a proxy for outbound requests.

Technical ContextAI

The vulnerability resides in the file upload handling mechanism of JeecgBoot's CommonController, specifically in the uploadImgByHttp endpoint and related utility classes (HttpFileToMultipartFileUtil). The root cause is classified as CWE-918 (Server-Side Request Forgery), which occurs when the application fetches remote resources based on user-supplied URLs without proper validation. The httpFileToMultipartFile and downloadImageData methods likely accept user-controlled URL parameters and directly fetch content from those URLs, allowing attackers to specify internal or external targets. JeecgBoot is a low-code development platform built on Java, and this vulnerability affects its file upload and image processing components.

RemediationAI

Upgrade JeecgBoot to the patched version once released by the vendor, or apply the fix referenced in GitHub issue #9555 (https://github.com/jeecgboot/JeecgBoot/issues/9555#issuecomment-4251745271). As an immediate compensating control, restrict network access to the uploadImgByHttp endpoint to trusted internal networks only and implement strict URL validation in the httpFileToMultipartFile method to whitelist allowed domains and block access to internal IP ranges (127.0.0.1, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, and cloud metadata endpoints). Additionally, enforce least-privilege access controls to limit the number of users who can authenticate to the application, reducing the attack surface. Monitor outbound HTTP/HTTPS requests originating from the application for suspicious destinations or patterns indicating SSRF exploitation.
