- Fix
3.3.0.3- Upgrade org.cloudfoundry.identity:cloudfoundry-identity-server to this version or later
Description
Pivotal Cloud Foundry 239 and earlier, UAA (aka User Account and Authentication Server) 3.4.1 and earlier, UAA release 12.2 and earlier, PCF (aka Pivotal Cloud Foundry) Elastic Runtime 1.6.x before 1.6.35, and PCF Elastic Runtime 1.7.x before 1.7.13 does not validate if a certificate is expired.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.cloudfoundry.identity:cloudfoundry-identity-server | >= 3.0.0, < 3.3.0.3 |
3.3.0.3 |
| org.cloudfoundry.identity:cloudfoundry-identity-server | >= 3.4.0, < 3.4.2 |
3.4.2 |
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-295: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How to prevent it
- Architecture and Design, Implementation: Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- Implementation: If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
