CVSS: 6.8EPSS: 0%CPEs: 1EXPL: 0CVE-2020-26244 – Cryptographic issues in Python oic
https://notcve.org/view.php?id=CVE-2020-26244
Python oic is a Python OpenID Connect implementation. In Python oic before version 1.2.1, there are several related cryptographic issues affecting client implementations that use the library. The issues are: 1) The IdToken signature algorithm was not checked automatically, but only if the expected algorithm was passed in as a kwarg. 2) JWA `none` algorithm was allowed in all flows. 3) oic.consumer.Consumer.parse_authz returns an unverified IdToken. The verification of the token was left to the discretion of the implementator. 4) iat claim was not checked for sanity (i.e. it could be in the future). These issues are patched in version 1.2.1. • https://github.com/OpenIDC/pyoidc/commit/62f8d753fa17c8b1f29f8be639cf0b33afb02498 https://github.com/OpenIDC/pyoidc/releases/tag/1.2.1 https://github.com/OpenIDC/pyoidc/security/advisories/GHSA-4fjv-pmhg-3rfg https://pypi.org/project/oic • CWE-325: Missing Cryptographic Step CWE-347: Improper Verification of Cryptographic Signature •

Doorkeeper::OpenidConnect (aka the OpenID Connect extension for Doorkeeper) 1.4.x and 1.5.x before 1.5.4 has an open redirect via the redirect_uri field in an OAuth authorization request (that results in an error response) with the 'openid' scope and a prompt=none value. This allows phishing attacks against the authorization flow. Doorkeeper::OpenidConnect (también conocido como extensión OpenID Connect para Doorkeeper) 1.4.x y 1.5.x anterior a la versión 1.5.4 tiene una redirección abierta mediante el campo redirect_uri en una petición de autorización OAuth (que resulta en una respuesta de error) con el alcance "openid" y un valor prompt=none. Esto permite ataques de phishing contra el flujo de autorización. • https://github.com/doorkeeper-gem/doorkeeper-openid_connect/blob/master/CHANGELOG.md https://github.com/doorkeeper-gem/doorkeeper-openid_connect/issues/61 https://github.com/doorkeeper-gem/doorkeeper-openid_connect/pull/66 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
