SQL injection in the OPC UA interface of Gallagher Security Command Centre allows remote authenticated users to modify its database. Gallagher has not disclosed which OPC UA request or database query fails to neutralize attacker-controlled SQL syntax. An unprivileged Command Centre Operator account is required, and enabled workstation restrictions also require a valid workstation certificate; exploitation permits undetected database modification.
