A vulnerability was identified in Consul and Consul Enterprise (“Consul”) such that using Headers in L7 traffic intentions could bypass HTTP header based access rules.
The product does not neutralize or incorrectly neutralizes web scripting syntax in HTTP headers that can be used by web browser components that can process raw headers, such as Flash.
The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.
