Pivotal Cloud Foundry On Demand Services SDK, versions prior to 0.24 contain an insecure method of verifying credentials. A remote unauthenticated malicious user may make many requests to the service broker with different credentials, allowing them to infer valid credentials and gain access to perform broker operations.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Broker_api Pivotal_software * 3.0.2 (excluding)
On_demand_services_sdk Pivotal_software * 0.24.0 (excluding)

Potential Mitigations

  • Common protection mechanisms include:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
