Vulnerability details
The vulnerability allows a remote user to escalate privileges to SQL sysadmin privileges.
The vulnerability exists due to execution with unnecessary privileges in Microsoft SQL Server's replication feature when handling operations involving a participating database or replication peer. A remote user can abuse unnecessarily privileged execution through access to a participating database or replication peer to gain SQL sysadmin privileges.
Exploitation requires the vulnerable replication feature and topology to be configured on the SQL Server instance. Access to a participating database or replication peer does not allow this server configuration to be enabled through the vulnerability.
