CVE NOT AVAILABLE CWE-287  (opens in a new tab)

How to fix?

Upgrade github.com/almeidapaulopt/tsdproxy/internal/proxymanager to version 3.0.0-alpha.3 or higher.

Overview

Affected versions of this package are vulnerable to Improper Authentication in the ReverseProxy.Rewrite process when the internal authentication token is forwarded to backend services via the x-tsdproxy-auth-token header. An attacker can gain unauthorized management API access and escalate privileges by capturing the token from a backend and replaying it from localhost to the management API. This is only exploitable if the backend service is able to reach the management API on 127.0.0.1:8080, such as in non-Docker deployments on the same host, Docker host-network-mode containers, or containers sharing the proxy's network namespace.
