Red Hat Product OCP Tools 4.12 update for Openshift Jenkins

1) Incorrect authorization

EUVDB-ID: #VU72076

Risk: High

CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-7692

CWE-ID: CWE-863 - Incorrect Authorization

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authorization process.

The vulnerability exists due to missing support for PKCE. Without the use of PKCE, the authorization code returned by an authorization server is not enough to guarantee that the client that issued the initial authorization request is the one that will be authorized. An attacker is able to obtain the authorization code using a malicious app on the client-side and use it to gain authorization to the protected resource.
