Description

HashiCorp Vault’s Microsoft SQL Database Storage Backend Vulnerable to SQL Injection Via Configuration File

HashiCorp Vault and Vault Enterprise versions 0.8.0 until 1.13.1 are vulnerable to an SQL injection attack when using the Microsoft SQL (MSSQL) Database Storage Backend. When configuring the MSSQL plugin, certain parameters are required to establish a connection (schema, database, and table) are not sanitized when passed to the user-provided MSSQL database. A privileged attacker with the ability to write arbitrary data to Vault's configuration may modify these parameters to execute a malicious SQL command when the Vault configuration is applied. This issue is fixed in versions 1.13.1, 1.12.5, and 1.11.9.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs administrative privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

  • Privileges required: High — administrative rights are needed first.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
