CVE-2023-23570Network attack vector

Authenticated invalid configuration via client-side enforcement

Published Dec 18, 2023 · Updated Nov 27, 2024

Client-side enforcement in Gallagher Command Centre allows remote authenticated users to create invalid server configurations. The Command Centre Server trusts security restrictions enforced only by its client, allowing modified client requests to bypass checks before configuration data is accepted. Low-privilege network access to the server is required, and Gallagher has not described the resulting undefined behavior more specifically.
