gin-vue-admin background arbitrary code coverage vulnerability

Vulnerability Description

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 pseudoversion 0.0.0-20240407133540-7bc7c3051067, corresponding to version 2.6.1, has a code injection vulnerability in the backend. In the Plugin System -> Plugin Template feature, an attacker can perform directory traversal by manipulating the `plugName` parameter. They can create specific folders such as `api`, `config`, `global`, `model`, `router`, `service`, and `main.go` function within the specified traversal directory. Moreover, the Go files within these folders can have arbitrary code inserted based on a specific PoC parameter. The main reason for the existence of this vulnerability is the controllability of the PlugName field within the struct. Pseudoversion 0.0.0-20240409100909-b1b7427c6ea6, corresponding to commit b1b7427c6ea6c7a027fa188c6be557f3795e732b, contains a patch for the issue. As a workaround, one may manually use a filtering method available in the GitHub Security Advisory to rectify the directory traversal problem.
