Description
Inappropriate user token revocation due to a logic error in the token revocation endpoint implementation in Cloudfoundry UAA v77.30.0 to v78.7.0 and in Cloudfoundry Deployment v48.7.0 to v54.10.0.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.cloudfoundry.identity:cloudfoundry-identity-server | >= 77.30.0, < 78.8.0 |
78.8.0 |
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.

Weakness
CWE-640: Weak Password Recovery Mechanism for Forgotten Password
The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
How to prevent it
- Architecture and Design: Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
- Architecture and Design: Do not use standard weak security questions and use several security questions.
- Architecture and Design: Make sure that there is throttling on the number of incorrect answers to a security question. Disable the password recovery functionality after a certain (small) number of incorrect guesses.
- Architecture and Design: Require that the user properly answers the security question prior to resetting their password and sending the new password to the e-mail address of record.
- Architecture and Design: Never allow the user to control what e-mail address the new password will be sent to in the password recovery mechanism.
- Architecture and Design: Assign a new temporary password rather than revealing the original password.
CWE-693: Protection Mechanism Failure
The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.
