Authenticated users can upload specifically crafted files to leak server resources. This behavior can potentially be used to run a denial of service attack against Cloud Controller.

The Cloud Foundry project recommends upgrading the following releases:

Upgrade capi release version to 1.194.0 or greater Upgrade cf-deployment version to v44.1.0 or greater. This includes a patched capi release

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.
