DescriptionCVE.org

A vulnerability was found in yangzongzhuan RuoYi-Vue up to 3.9.2. This impacts the function fileDownload/resourceDownload of the file ruoyi-admin/src/main/java/com/ruoyi/web/controller/common/CommonController.java of the component Common Download Endpoint. Performing a manipulation of the argument fileName/resource results in path traversal. It is possible to initiate the attack remotely. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Path traversal in RuoYi-Vue up to 3.9.2 allows authenticated low-privilege users to read arbitrary files from the server filesystem by manipulating the fileName or resource parameters of the Common Download Endpoint in CommonController.java. A publicly available exploit has been disclosed via GitHub issue, but no patch has been released and the maintainer has not responded to the disclosure. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid low-privilege authenticated session in RuoYi-Vue - the CVSS 4.0 PR:L metric confirms authentication is necessary, and unauthenticated exploitation is not indicated. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) scores 5.3, classifying this as medium severity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated user with a low-privilege account on a RuoYi-Vue instance sends an HTTP request to the Common Download Endpoint with a `fileName` parameter set to a path traversal string such as `../../WEB-INF/classes/application.yml`, causing the server to resolve and return the contents of sensitive configuration files outside the intended download directory. The public exploit referenced in GitHub issue #151 demonstrates this technique, making reproduction straightforward for any session holder without requiring advanced tooling.
Remediation No vendor-released patch has been identified at time of analysis - the maintainer has not responded to the GitHub issue disclosure at https://github.com/yangzongzhuan/RuoYi-Vue/issues/151. … Detailed patch versions, workarounds, and compensating controls in full report.
