Frequently Asked Questions
1
What level of access does an attacker need to exploit this issue?
The attacker must be authorized and able to reach the SQL Server instance over the network. The available data does not identify the specific SQL Server permissions or role required.
2
Is user interaction required for exploitation?
No. The vector indicates that exploitation does not require user interaction once an authorized attacker has network access.
3
What is the potential impact of successful exploitation?
Successful exploitation can allow code execution and may result in high impacts to confidentiality, integrity, and availability. The scope is changed, indicating impacts may extend beyond the vulnerable SQL Server security authority.
