CVE-2019-3788: UAA redirect-uri allows wildcards in the subdomain


Severity

High

Vendor

Pivotal Cloud Foundry

Description

Pivotal Application Service (2.3.x versions prior to 2.3.14, 2.4.x versions prior to 2.4.10, and 2.5.x versions prior to 2.5.5), Pivotal Container Service (1.3.x versions prior to 1.3.7), and Pivotal Ops Manager (2.3.x versions prior to 2.3.20, and 2.4.x versions prior to 2.4.14, and 2.5.x versions prior to 2.5.1), through their dependency on a vulnerable version of UAA (57.x versions prior to 57.10, 60.x versions prior to 60.14, 64.x versions prior to 64.2, and 66.x versions prior to 66.1), allows clients to be configured with an insecure redirect uri. Given a UAA client was configured with a wildcard in the redirect uri's subdomain, a remote malicious unauthenticated user can craft a phishing link to get a UAA access code from the victim.
