Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.
In a few clicks we can analyze your entire application and see what components are vulnerable in your application, and suggest you quick fixes.
Test your applicationsUpgrade github.com/dexidp/dex/server to version 2.35.0 or higher.
Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) by allowing an attacker to capture the ID token via intercepted authorization code. An attacker can exploit this vulnerability by making a victim navigate to a malicious website and guiding them through the OIDC flow, stealing the OAuth authorization code in the process. The authorization code then can be exchanged by the attacker for a token, gaining access to applications accepting that token.
** Note: **
PKCE does not defend against this attack since the webserver initiates the request to Dex with a known code challenge.
Users who are unable to upgrade to the fixed version can disable public clients.
