Cloud Foundry Foundation UAA, versions 4.12.X and 4.13.X, introduced a feature which could allow privilege escalation across identity zones for clients performing offline validation. A zone administrator could configure their zone to issue tokens which impersonate another zone, granting up to admin privileges in the impersonated zone for clients performing offline token validation.

In Cloud Foundry Foundation cf-release versions prior to v285; cf-deployment versions prior to v1.7; UAA 4.5.x versions prior to 4.5.5, 4.8.x versions prior to 4.8.3, and 4.7.x versions prior to 4.7.4; and UAA-release 45.7.x versions prior to 45.7, 52.7.x versions prior to 52.7, and 53.3.x versions prior to 53.3, the SessionID is logged in audit event logs. An attacker can use the SessionID to impersonate a logged-in user.

The identity zones feature in Pivotal Cloud Foundry 208 through 229; UAA 2.0.0 through 2.7.3 and 3.0.0; UAA-Release 2 through 4, when configured with multiple identity zones; and Elastic Runtime 1.6.0 through 1.6.13 allows remote authenticated users with privileges in one zone to gain privileges and perform operations on a different zone via unspecified vectors.
