CVE-2018-15795: CredHub Service Broker uses guessable client secret

Pivotal CredHub Service Broker, versions prior to 1.1.0, uses a guessable form of random number generation in creating service broker's UAA client. A remote malicious user may guess the client secret and obtain or modify credentials for users of the CredHub Service.

Glexia's TakeAutomated analysis

Security readout for executives and security teams

CredHub Service Broker could create a UAA client secret with guessable randomness. If an attacker with high privileges and adjacent network access guessed it, they could access or change credentials managed through the CredHub Service. This is a high-severity credential-control issue, but the provided sources do not show active exploitation. Exposure is likely limited to environments running Pivotal Cloud Foundry CredHub Service Broker before version 1.1.0. The CVSS vector indicates adjacent network access and high privileges are required, so internet-wide exposure is not supported by the provided sources. Treat as high priority where CredHub Service Broker is present because successful misuse could expose or alter sensitive credentials. Prioritize inventory and remediation in Cloud Foundry environments, especially those handling production secrets. Mitigation focus: Identify any CredHub Service Broker deployments before version 1.1.0.; Review the Pivotal advisory for fixed release and operational remediation guidance.; Plan upgrade away from affected CredHub Service Broker versions..
