Additional Advisory Data
Solutions
CNA: Users of SALTO ProAccess using the tenancy feature should upgrade to version 6.13. To further enhance security after applying the update: * Operate ProAccess Space on a protected internal network and avoid exposing it directly to the Internet. * Restrict operator-level accounts to the minimum required and apply least-privilege principles. * If feasible, disable the partitioning feature and operate under a single partition. * When strong tenant separation is required, consider running separate Space instances (isolated environments) rather than relying solely on logical partitioning.
