### Summary The RedirectSlashes function in middleware/strip.go is vulnerable to host header injection which leads to open redirect. ### Details The RedirectSlashes method uses the Host header to construct the redirectURL at this line https://github.com/go-chi/chi/blob/v5.2.1/middleware/strip.go#L55 The Host header can be manipulated by a user to be any arbitrary host. This leads to open redirect when using the RedirectSlashes middleware ### PoC Create a simple server which uses the RedirectSlashes middleware ``` package main import ( "fmt" "net/http" "github.com/go-chi/chi/v5" "github.com/go-chi/chi/v5/middleware" // Import the middleware package ) func main() { // Create a new Chi router r := chi.NewRouter() // Use the built-in RedirectSlashes middleware r.Use(middleware.RedirectSlashes) // Use middleware.RedirectSlashes // Define a route handler r.Get("/", func(w http.ResponseWriter, r *http.Request) { // A simple response w.Write([]byte("Hello, World!")) }) ...

DNN.PLATFORM allows a specially crafted series of malicious interaction can expose NTLM hashes to a third party SMB server. This vulnerability is fixed in 10.0.1.

DNN.PLATFORM allows a specially crafted request or proxy could be created that would bypass the design of DNN Login IP Filters allowing login attempts from IP Adresses not in the allow list. This vulnerability is fixed in 10.0.1.

DNN.PLATFORM allows a specially crafted request can inject scripts in the Activity Feed Attachments endpoint which will then render in the feed, resulting in a cross-site scripting attack. This vulnerability is fixed in 10.0.1.

DNN.PLATFORM allows specially crafted content in URLs could be used with TokenReplace and not be properly sanitized by some SkinObjects. This vulnerability is fixed in 10.0.1.

### Impact Under specific circumstances, text composables may contain unmasked sensitive data in Android session replays. You may be impacted if you meet the following conditions: - Using any `sentry-android` with versions < 8.14.0 - Using Jetpack Compose >= [1.8.0-alpha08](https://developer.android.com/jetpack/androidx/releases/compose-ui#1.8.0-alpha08) - Have configured Sentry Session Replays for Android If you do not use Jetpack Compose or have never used a version >= 1.8.0-alpha08 you are not impacted. If you have not configured [Session Replays for Mobile](https://docs.sentry.io/product/explore/session-replay/mobile/) you are not impacted. ### How do I check if I'm impacted? If you meet the conditions above, the `sentry-android` package includes a [specific error log](https://github.com/getsentry/sentry-java/blob/b2920907e6afb69a8027cedb251dd94a3514f0e6/sentry-android-replay/src/main/java/io/sentry/android/replay/viewhierarchy/ComposeViewHierarchyNode.kt#L252-L261) that woul...

Mattermost versions 10.5.x <= 10.5.5, 9.11.x <= 9.11.15, 10.8.x <= 10.8.0, 10.7.x <= 10.7.2, 10.6.x <= 10.6.5 fail to sanitize filenames in the archive extractor which allows authenticated users to write files to arbitrary locations on the filesystem via uploading archives with path traversal sequences in filenames, potentially leading to remote code execution. The vulnerability impacts instances where file uploads and document search by content is enabled (FileSettings.EnableFileAttachments = true and FileSettings.ExtractContent = true). These configuration settings are enabled by default.

Velociraptor allows collection of VQL queries packaged into Artifacts from endpoints. These artifacts can be used to do anything and usually run with elevated permissions.  To limit access to some dangerous artifact, Velociraptor allows for those to require high permissions like EXECVE to launch. The Admin.Client.UpdateClientConfig is an artifact used to update the client's configuration. This artifact did not enforce an additional required permission, allowing users with COLLECT_CLIENT permissions (normally given by the "Investigator" role) to collect it from endpoints and update the configuration. This can lead to arbitrary command execution and endpoint takeover. To successfully exploit this vulnerability the user must already have access to collect artifacts from the endpoint (i.e. have the COLLECT_CLIENT given typically by the "Investigator' role).
