Summary

CentreStack before 17.2 contains an authentication bypass vulnerability that allows unauthenticated attackers to read, write, or delete arbitrary account settings by exploiting exposed API endpoints that lack authorization checks. Attackers can generate valid encrypted EntAcctId values using the static shared encryption key to forge identifiers for any user GUID, including the system-wide cluster settings account, enabling enumeration of hosted tenant domains and administrator identities.
