Privileged protocol downgrade via untrusted configuration input

Security-decision input misuse in Gallagher Diagnostics Service before 1.3.0 allows remote authenticated users to weaken communications. Gallagher has not disclosed which configuration input is trusted incorrectly or how the service applies it when selecting communication protocols. Privileged access is required, and the resulting configuration permits the service to use less secure protocols for diagnostic communications.
