Cloudreve: Path Traversal / Broken Access Control in Cloudreve WebDAV (`/dav`) — scoped DAV credential escapes its configured account root

7.1 HighFix available

Cloudreve is a self-hosted file management and sharing system. Prior to 4.16.1, a Cloudreve WebDAV account rooted at a configured folder can send paths such as /dav/%2e%2e/outside.txt because stripPrefix in pkg/webdav/webdav.go joins the decoded request suffix to the account root with fs.URI.JoinRaw without checking containment, allowing the scoped credential to read and list files outside the configured folder and writable credentials to create, overwrite, move, or delete them. This issue is reported as fixed in version 4.16.1.

Cloudreve WebDAV (`/dav`) has Path Traversal / Broken Access Control — scoped DAV credential escapes its configured account root

Summary

A Cloudreve WebDAV account stores a uri that defines the account's root folder. The WebDAV request handler (stripPrefix in pkg/webdav/webdav.go) trims the /dav prefix from the request path and joins the remainder to that root with fs.URI.JoinRaw, but never checks that the joined URI stays inside the root.

Go's net/http decodes %2e%2e to .. and %2f to / in r.URL.Path before the handler sees it, and JoinRaw resolves .. segments through the standard library's url.URL.JoinPath. A request such as GET /dav/%2e%2e/outside.txt against a credential rooted at cloudreve://my/restricted therefore resolves to cloudreve://my/outside.txt. A scoped DAV credential can read and list files outside its configured folder; a writable scoped credential can also create, overwrite, move, and delete them.

The escape stays inside the same Cloudreve user's namespace because downstream DBFS owner checks still apply. It does not cross into another user's files or onto the OS filesystem. What it breaks is the per-folder WebDAV-account boundary — the entire reason scoped DAV accounts exist (delegating limited access to a sync client or a third party).

Technical Detail

Root cause

stripPrefix joins the request suffix onto the account base with no containment check:

// pkg/webdav/webdav.go @ 54dc81d
func stripPrefix(p string, u *ent.User) (string, *fs.URI, int, error) {
	base, err := fs.NewUriFromString(u.Edges.DavAccounts[0].URI)
	if err != nil {
		return "", nil, http.StatusInternalServerError, err
	}

	prefix := davPrefix // "/dav"
	if r := strings.TrimPrefix(p, prefix); len(r) < len(p) {
		r = strings.TrimPrefix(r, fs.Separator)
		return r, base.JoinRaw(util.RemoveSlash(r)), http.StatusOK, nil // <-- join, no boundary check
	}
	return "", nil, http.StatusNotFound, errPrefixMismatch
}

JoinRaw splits on / and delegates to the standard library:

// pkg/filemanager/fs/uri.go @ 54dc81d
func (u *URI) JoinRaw(elem string) *URI {
	return u.Join(strings.Split(strings.TrimPrefix(elem, Separator), Separator)...)
}

func (u *URI) Join(elem ...string) *URI {
	newUrl, _ := url.Parse(u.U.String())
	return &URI{U: newUrl.JoinPath(lo.Map(elem, func(s string, i int) string {
		return PathEscape(s)
	})...)}
}

PathEscape leaves a . untouched (shouldEscape returns false for .), so the literal segment .. survives into url.URL.JoinPath, which cleans the path and resolves the parent reference.

Proof of Concept

The full server was not run from the checkout (the embedded frontend asset assets.zip is absent from source), so the chain was proven by exercising the two decisive layers with real code rather than a screenshot of a live instance.

Layer 1 — net/http hands the handler a decoded, uncleaned path

A standard-library HTTP server, hit over a real socket with raw request targets (equivalent to curl --path-as-is), shows what c.Request.URL.Path holds inside the handler:

REQUEST: GET /dav/%2e%2e/outside.txt
  handler observed: URL.Path="/dav/../outside.txt"   RawPath="/dav/%2e%2e/outside.txt"   -> 200
REQUEST: PROPFIND /dav/%2e%2e/
  handler observed: URL.Path="/dav/../"              RawPath="/dav/%2e%2e/"               -> 200
REQUEST: PUT /dav/%2e%2e/created-outside.txt
  handler observed: URL.Path="/dav/../created-outside.txt"                                 -> 200
REQUEST: GET /dav/%2F..%2Foutside.txt
  handler observed: URL.Path="/dav//../outside.txt"  RawPath="/dav/%2F..%2Foutside.txt"   -> 200

The path is decoded but never cleaned. Gin does not rewrite Request.URL.Path, so the Cloudreve handler observes the same value.

Layer 2 — Cloudreve's URI resolution escapes the root

Re-running Cloudreve's exact PathEscape / shouldEscape / Join / JoinRaw / NewUriFromString code (copied verbatim from uri.go @ 54dc81d) against the real net/url library, with base cloudreve://my/restricted:
