Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
The package github.com/hashicorp/vault versions through 1.11.8, 1.12.0-rc1 through 1.12.4 , 1.13.0-rc1 and 1.13.0 are vulnerable to an SQL injection attack when configuring the Microsoft SQL (MSSQL) Database Storage Backend. When configuring the MSSQL plugin through the local, certain parameters are not sanitized when passed to the user-provided MSSQL database. An attacker may modify these parameters to execute a malicious SQL command.
CWE-89 - SQL Injection
Structured Query Language (SQL) injection attacks are one of the most common types of vulnerabilities. They exploit weaknesses in vulnerable applications to gain unauthorized access to backend databases. This often occurs when an attacker enters unexpected SQL syntax in an input field. The resulting SQL statement behaves in the background in an unintended manner, which allows the possibility of unauthorized data retrieval, data modification, execution of database administration operations, and execution of commands on the operating system.
