4.23.0- Upgrade org.cloudfoundry.identity:cloudfoundry-identity-server to this version or later
Description
Cloud Foundry UAA release, versions prior to v64.0, and UAA, versions prior to 4.23.0, contains a validation error which allows for privilege escalation. A remote authenticated user may modify the url and content of a consent page to gain a token with arbitrary scopes that escalates their privileges.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.cloudfoundry.identity:cloudfoundry-identity-server | < 4.23.0 |
4.23.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
