Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Code.cloudfoundry.org/gorouter, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Cloud Foundry Routing, all versions before 0.0.0-20191101214924-b1b5c44e050f, does not properly validate nonce input. A remote unauthorized malicious user could forge a route service request using an invalid nonce that will cause the Gorouter to crash.
