Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Github.com/skupperproject/skupper, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A flaw was found in Skupper. When Skupper is initialized with the console-enabled and with console-auth set to Openshift, it configures the openshift oauth-proxy with a static cookie-secret. In certain circumstances, this may allow an attacker to bypass authentication to the Skupper console via a specially-crafted cookie.
