Recommendation: Monitor — no exploitation signal at the moment.

An insufficient validation on the server connection endpoint in Netskope Client allows local users to elevate privileges on the system. The insufficient validation allows Netskope Client to connect to any other server with Public Signed CA TLS certificates and send specially crafted responses to elevate privileges.
