A vulnerability in APIML Spring Cloud Gateway which leverages user privileges by unexpected signing proxied request by Zowes client certificate. This allows access to a user to the endpoints requiring an internal client certificate without any credentials. It could lead to managing components in there and allow an attacker to handle the whole communication including user credentials.
The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses.
