The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability. According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? An attacker could exploit the vulnerability by tricking an authenticated user (CVSS metric UI:R) into attempting to connect to a malicious SQL server via a connection driver (for example: ODBC and / or OLEDB as applicable).
