Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an SQL injection issue in Microsoft SQL Server where special elements used in an SQL command are not properly neutralized. This flaw allows an authorized attacker to execute malicious SQL commands that can elevate their privileges over a network.
How can this vulnerability impact me? :
The impact of this vulnerability is an elevation of privilege, meaning an attacker who already has some level of access can gain higher privileges. This can lead to full control over the SQL Server, potentially compromising confidentiality, integrity, and availability of the data and services.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
